The achievements of plant breeding have had tremendous on economic and national development. Some banana genotypes are rich in provitamin . THE 5 TH INTERNATIONAL PLANT BREEDING CONFERENCE 2022 (IPBC2022) Emerging Trends in Plant Breeding Towards Sustainable Bioeconomy. Mutation breeding has been suggested as an excellent alternative approach for banana improvement (Guzman, 1975). It is also the fourth largest food crops in the world (Perrier et al. Scope of vegetable improvement through biotechnological approaches • Genetic improvement of vegetable crops through biotechnological approach in India is at its embryonic stage. Since cross-pollinated species are naturally hybrid (heterozygous) for many traits and lose vigour as they become purebred (homozygous), a goal of each of these breeding methods . The International Maize and Wheat Improvement Center and partners have developed MLN-tolerant hybrids through conventional breeding. This article highlights advances in breeding trans-genic vegetables and fruits, and issues affecting their use, as illustrated by the case studies of tomato, potato, eggplant, squash, sweet corn, papaya, plum and banana and by the contribution of transgenic vegetables and This overview indicates that much is possible with conventional breeding, although not everything. . . 0 Reviews. Consequently, people may think of the fruits and vegetables commonly available in grocery markets as natural, while attempts to modify these familiar prod-ucts, whether by conventional means or by genetic en-gineering, may be regarded with suspicion. Breeding banana and plantain: from intractability to feasibility "A broad-based, improved Musa germplasm with pest and disease resistance will be a major component to achieve sustainable production of this vegetatively propagated, perennial crop. 1981). These methods are particularly useful with banana, a plant that is difficult to breed through conventional methods. Bananas and plantains are among the most important food and cash crops in the world. Improvement of resistance to Fusarium wilt in susceptible cultivars is being addressed through both conventional and advanced breeding approaches. 5th International Plant Breeding Conference 2022. The conventional breeding approach in banana was slow predominantly because of the limited genetic diversity, infertility and polyploid condition of the species. Fusarium species isolated from common weeds in eggplant fields and symptomless hosts of Fusarium oxysporum f. sp. 2016). 1.2. Our approach to improving bananas is through genetic modification either alone or in combination with conventional breeding. Mutation breeding is offering a unique, alternative approach for the improvement of banana has also been employed to develop new cultivars. Plant breeding is an important field of research for improvement of yield and quality of plant production. The conventional breeding programme at the Banana Research Station, Kannara, India has produced two dessert banana hybrids, 'BRS-1', ['Agniswar' (AAB) × 'Pisang Lilin' (AA)] and 'BRS-2', ['Vannan' (AAB) × 'Pisang Lilin'], which have been developed and released for cultivation in Kerala. through conventional hybridization or tissue-culture techniques. 3. Presence of the integrated endogenous banana streak virus (eBSV) in the B genome of plantain (AAB) is a major challenge for breeding and dissemination of hybrids. Banana streak virus was not considered a severe threat to banana production until early 2,000. S.Backiyarani. Genetic transformation to achieve pest and disease resistance is a promising strategy for smallholder farmers in this region: biotic constraints are severe there and not easily addressed through conventional breeding or control methods. Abstract : The IITA carries out plantain and banana improvement research with three predominant themes: advancement of breeding methodologies to increase the efficiency of hybrid development in plantains and East African Highland bananas, development of superior bananas, and technology transfer and human resource development in sub-Saharan Africa. Celebesensis. Introduction. In 2005, the Centre for Tropical Crops and Biocommodities (now . Acta Hortic. This manuscript also highlights the genetic knowledge accumulated in this crop that will facilitate the use of new approaches in its improvement. They are cheap to produce, grow in a range of environments, and produce fruit year-round. Genetic improvement of bananas is essential if this incredibly valuable food crop is to continue to make major contributions to food security in the future. Thus, banana breeding . Acta Hortic. These are : 1) an increasing awareness of the vulnerability of bananas and plantains to attack by various disease organisms and insect pests, 2) an acknowledgement of the difficulty of breeding these crops using conventional techniques, and 3) the recognition of musacearum (Xcm) is the most economically important bacterial disease affecting banana production, particularly in the African Great Lakes region. 2. Improvement of Cavendish banana cultivars through conventional breeding. Much of the current interest inMusaimprovement can be attributed to three factors. Banana Improvement Preface Banana and plantain ( Musa spp.) Development of molecular markers linked to major traits is expected to speed up the improvement process. Papers should be submitted through online and will be blind reviewed by two reviewers. has considerable experience with both conventional and marker-assisted breeding of several vegetable and fruit crops . J. Phytopathol. The challenge is that nearly all banana cultivars and landraces are triploids, with high levels of male and female infertility. production constraints sustainably requires deployment of improved varieties, but the improvement of EA-AAA banana through conventional breeding is very difficult due to its ploidy and limited genetic diversity. Improvement and management of banana genetic resources in Indian subcontinent. More genetically diverse clones are essential for .

Since banana is a vegetatively propagated crop, its production is affected due to the build-up of several pests and pathogens, particularly where . Mutagenic treatments on banana plants have been reported and in vivo sucker material has proved to be less effective and yielded low 107 mutagenized material for further screening [6,7]. Keywords Musa Breeding strategies Sterility Parthenocarpy Fertility Download chapter PDF Introduction But the process is resource-intensive and takes about four-to-five years. Banana is one of the most economically important fruits in tropics (Picq et al. The genetic improvement of Musa using conventional breeding, and modern tools of molecular and cellular biology Jean Vincent Escalant, Suzanne Sharrock and Emile Frison, with the collaboration of. 136 improvement of banana through conventional breeding is hampered by several reasons such as very low clonal multiplication rates, parthenocarpic fruit development, polyploidy with extremely poor seed production and low levels of female fertility. Protoplast technology is an important adjunct to conventional plant breeding. 986:205-208. During fertilization in an-giosperms, pollen grains must reach the stigma of the host . 2000). Banana is the common name used for the herbaceous plants of the genus Musa which is cultivated in more than 100 countries throughout the tropics and sub-tropics, with an annual world production of around 98 million tonnes, of which around a third is produced in each of the African, Asia-Pacific, and Latin American and Caribbean regions (Frison & Sharrock, 1999). Conventional breeding is just one part of an integrated improvement banana scheme. Genetic variation is the starting point of any breeding program. Bananas and plantains are among the most important food and cash crops in the world. Marker-assisted selection is a molecular breeding technique which is becoming popular because it offers the possibility of significantly reducing the amount of time taken for banana improvement when using conventional cross-breeding, which requires one and a half years for the crop to complete its growth cycle and produce new plantlets (Pillay . Aguilar Morán Abstract In their article Banana breeding: polyploidy, disease resistance and productivity , Stover and Buddenhagen (1986) reported the results of the evaluation of female fertility in Cavendish banana cultivars. No other commercial export type of banana exists at present as an alternative to the 'Cavendish' clones, and breeding advanced diploid male pollinator lines must make all genetic improvements to reduce the expense of chemical control. The basement room is the size of a semitrailer. Furthermore, research is advancing rapidly in the use of molecular markers as a breeding tool, and the molecular characterisation of germplasm. Therefore, to develop an edited 'non-GM' banana, it will probably be necessary to only transiently express, for instance, the guide RNA and the Cas9 protein, perhaps as a ribonucleoprotein and the edited cell will need to be . Banana breeders could increase breeding efficiency by exploiting technologies such as induced mutations, tissue culture, somatic embryogenesis, organogenesis, somaclonal variation, and embryo rescue. 130 million metric tonnes. vegetable and fruit species through conventional breeding. 161:335-340. The genetic improvement of bananas extends excellent prospects for enhancing food security as it supports more people per unit area of production than other staple crops (Tripathi et al., 2019a). In . Banana Xanthomonas wilt (BXW), caused by Xanthomonas campestris pv. melongenae in Turkey. Banana streak virus was first detected in Cote D'Ivoire about 50 years . The institute maintains banana collections in Nigeria, Tanzania and Uganda that contributes through its genetic improvement efforts through conventional breeding and genetic transformation. Traditional breeding is difficult due to its triploid genome and sterility (Dash et al. 2008) evidenced the success of conventional breeding approaches in banana improvement. This research agenda is largely implemented . Due to the low fertility and long generation times of conventional breeding with Musa germplasm, exploitation of resistance genes that have been identified in diploid banana species has been slow. These programs employ colchicine to duplicate chromosomes and aim to develop new cultivars rather than improving available germplasm (Tomepke et al., 2004 ). In 1991, IITA set up the Plantain and Banana Improvement Program in response to the increasing pest and disease pressure on the crop3. Abstract : The IITA carries out plantain and banana improvement research with three predominant themes: advancement of breeding methodologies to increase the efficiency of hybrid development in plantains and East African Highland bananas, development of superior bananas, and technology transfer and human resource development in sub-Saharan Africa.

In the five past years, breeding programmes in sub-Saharan Africa, tropical America and Asia have developed, through conventional cross breeding and induced mutation or somaclonal variation, improved germplasm (desert and cooking banana, and plantains) for local consumption. Grande Naine (Cavendish - AAA) for Fusarium wilt resistance through non-conventional breeding. Mutation breeding in vitro is a powerful tool for the induction and selection of desirable mutants which can be utilized in banana improvement [5]. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. Strengthening of banana breeding through data digitalization Abstract Improvement of edible bananas (a triploid and sterile crop) through conventional breeding is a challenging task owing to its recalcitrant nature for seed set, prolonged crop duration. 2011) - Embrapa, CIRAD, NARITA and FHIA (Dela Cruz et al. Banana breeding through conventional approach is key to overcoming yield losses to bacterial phytopathogens. Mutation induction resulting by the induced mutation through gamma ray irradiation is an alternative technique in developing/generating bananas with improved traits. Though it has known female fertile cultivars, the EA-AAA banana is characterized by high female and male sterility However, engineering of banana endosphere with bacterial endophytes from resistant genotypes like Pisang lilly and YKM5 will induce the immune response against Foc, irrespective of races. Such germplasm can be produced through conventional cross-breeding, enhanced by the utilization of Desirable trait can be fixed in banana in the first generation of hybrid progenies, but their evaluation is a long process owing to non . In addition to the above, CIRAD and CARBAP also have advanced breeding programs that have also developed banana hybrids resistant to P. fijiensis through conventional strategies. Unlike most other major food crops, bananas are difficult to genetically improve. As Tripathi explained in this video interview, newer breeding methods are precise, which avoids incorporating undesirable traits in the improved varieties. There are a number of international conventional breeding programs and many of these are developing new cultivars. Banana Improvement. 1. Springer, Sep 8, 2016 - Science - 346 pages.

Such germplasm can be produced through conventional cross-breeding, enhanced by the utilization of The presence of residual female fertility in most of the parthenocarpic banana accessions, embryo culture technique encourages the banana breeder to develop new hybrids through conventional breeding. . As the eBSV activates into . Conventionally bred banana varieties have struggled with consumer acceptability due to their . Interspecific and . the first step is to generate a breeding population that is highly variable for traits that are agriculturally interesting. Crossref, Google Scholar; Altinok, H. H. 2013. Breeding banana is difficult and expensive, as commercial varieties are sterile triploids (3×) and also a high degree of cross incompatibility can exist among the fertile groups. No other commercial export type of banana exists at present as an alternative to the 'Cavendish' clones. Conventional breeding is widely used, but presents several limitations • Molecular techniques can be applied to assist and optimize conventional breeding • New biotechnological tools allow the engineered introduction of quality traits • Genetic engineering approaches still present public and regulatory concerns Abstract Background Genome-editing can complement conventional breeding by speeding up crop improvement process. The most important methods of breeding cross-pollinated species are (1) mass selection; (2) development of hybrid varieties; and (3) development of synthetic varieties. Edible bananas are mostly sterile polyploids and must be propagated vegetatively. 161:335-340. Building 13, a plain two-story brick structure within the castle walls, houses the world's largest collection of banana varieties. This is not possible with bananas unless the edited banana is to be used in a conventional breeding programme. Currently . Genetic engineering is perhaps the only way to improve this important staple food and . Since several of these crops, such as cassava, banana, plantain and sweet potato are propagated from vegetative parts, in vitro culture techniques in combination with mutagenesis can speed up the improvement of these crops through . crop varieties, without going through extensive hybridization and back crossing used in conventional breeding.

"Genetic engineering…allows the transfer of useful traits from different species or across the same species, bypassing natural bottlenecks of breeding, thus making it applicable for the improvement of banana," they wrote. Hence, given the difficulties in conventional breeding, mutation breeding was attempted to induce variability and obtain improved banana varieties. crop improvement, through breeding, wide hybridization, haploidy, somaclonal variation and micropropagation, are . They are cultivated in more than 135 countries, across the tropics and subtropics, with an . Conversely, these resistant sources can be exploited for improving the commercial cultivars through conventional breeding complemented with marker-assisted selection. Improvement of cv. Consequently, BSV is considered as a major constraint in banana breeding programs, restricting the use of the diploid progenitor M. balbisiana or its derivants carrying a B genome as parents for introgression of desirable agronomic traits6. The conventional breeding programme at the Banana Research Station, Kannara, India has produced two dessert banana hybrids, 'BRS-1', ['Agniswar' (AAB) × 'Pisang Lilin' (AA)] and 'BRS-2', ['Vannan' (AAB) × 'Pisang Lilin'], which have been developed and released for cultivation in Kerala. Conventional breeding achieves it by crossing together plants with relevant characteristics, and selecting the offspring with the desired combination of characteristics, as a result of particular combinations of genes inherited from the two parents. J. Phytopathol. Breeding banana and plantain: from intractability to feasibility "A broad-based, improved Musa germplasm with pest and disease resistance will be a major component to achieve sustainable production of this vegetatively propagated, perennial crop. sub-tropical countries. It also provides details on the approaches used and steps throughout the breeding process: crossing, screening, testing, selecting and identifying promising hybrids for further cultivar releases.
