“…Micropropagation has played a key role in banana and plantain breeding programs worldwide (Rowe and Rosales 1996;Vuylsteke et al 1997). Different explants have been tested for propagation of banana and plantain with shoot tips being the most common explant for in vitro propagation of commercial cultivars (Kulkarni et al 2004(Kulkarni et al , 2006.…”

“…Long generation time, various levels of ploidy, lack of genetic variability, and sterility of most edible cultivars have hampered the development of disease-resistant Musa by conventional breeding (Stover and Buddenhagen 1986;Stover and Simmonds 1987;Swennen and Vuylsteke 1993;Musoke et al 1999;Pillay et al 2004;Tripathi et al 2004). In vitro micropropagation has played a key role in clonal propagation of banana for obtaining large numbers of homogenous plants and breeding of plantains and bananas (Pierik 1987;Rowe and Rosales 1996;Vuylsteke et al 1997;Kalimuthu et al 2007;Al-Amin et al 2009). …”

In vitro propagation has played a key role for obtaining large numbers of virus free, homogenous plants, and for breeding of plantains and bananas (Musa spp.). Explant sources utilized for banana micropropagation include suckers, shoot tips, and floral buds. The present study employed male floral meristems as explant material for micropropagation of hill banana ecotypes (AAB) 'Virupakshi' and 'Sirumalai.' Immature male floral buds were collected from healthy plants from hill banana growing areas. Exposure of explants to ethyl alcohol (70%, v/v) for 30 s, then mercuric chloride (0.1%, w/v) for 30 s, followed by three independent rinses of 5 min each in autoclaved, double-distilled water satisfactorily reduced the contamination. Male floral bud explants were cultured on Murashige and Skoog (MS) basal medium supplemented with different combinations of 6-benzylaminopurine (BAP), coconut water, naphthaleneacetic acid, gibberellic acid, and additional supplements. MS medium supplemented with 5 mg l −1 BAP and coconut water (15%) was the most efficient media for shoot initiation and multiple shoot formation (15 shoots from a single part of a floral bud). The best response for shoot elongation was obtained using the combination of basal MS, 5 mg l −1 BAP, 1 mg l −1 naphthaleneacetic acid and 1.5 mg l −1 gibberellic acid. Regenerated shoots were rooted in basal MS medium within 15-20 d. The rooted plantlets were transferred to a soil mixture and maintained at a temperature of 25±2°C for 10 d and then at room temperature (30-32°C) for 2 wk, before transferring to a greenhouse. The regenerated plantlets showed 100% survival.

, CLÁUDIA FORTES FERREIRA 5 , MIGUEL ANGEL DITA RODRIGUEZ 6 RESUMO-A banana cultivada 107 países, em uma área de 4,1 milhões de hectares e produção de 95 milhões de toneladas, é segunda fruta mais produzida do mundo. A bananeira é atacada por vírus (CMV e BSV), fungos (Sigatoka amarela e negra, mal-do-Panamá), bactéria (Moko), nematoide e insetos (Broca do rizoma). No entanto, por meio do melhoramento genético é possível obter resistência a maioria das pragas e doenças. O centro de origem de grande parte do germoplasma de Musa spp. é o Continente Asiático, onde são encontradas bananeiras diploides, triploides tetraploides, com genomas de Musa acuminta e M. balbisiana. No melhoramento de banana, feito principalmente para resistência às doenças, são usados os seguintes métodos: introdução e seleção de clones; hibridação (cruzamentos de diploides com diploides, triploides com diploides e diploides com tetraploides); duplicação de cromossomos; mutação e transgenia. Os métodos que envolvem hibridação, embora sejam os mais usados, apresentam limitações como a partenocarpia, a esterilidade; o número variável de ploidia e a baixa produção de sementes. Todo material produzido no programa, é depois avaliado nas regiões produtoras de banana. Atualmente novas técnicas de melhoramento, baseadas em informações genéticas de Musa spp. estão sendo incrementadas. Termos para indexação: hibridação, duplicação de cromossomos, mutação e transgenia. GENETIC IMPROVEMENT OF BANANA: STRATEGIES AND AVAILABLE TECHNOLOGIESABSTRACT -Bananas are cultivated in more than 107 countries in an area of 4.1 million hectares with a production of 95 million tons and considered the second most produced fruit worldwide. Bananas are attacked by viruses (CMV and BSV), fungi (Yellow and Black Sigatoka and Fusarium), bacteria (Moko), nematodes and insects (Weevils). However, through genetic breeding, it is possible to achieve resistance to most pests and diseases. The center of origin of most of Musa spp. germplasm is the Asian Continent, where diploid, triploid, Tetraploid with genome Musa acuminata and Musa balbisiana bananas are found. In banana breeding, especially for disease resistance, the following methods are employed: introduction and selection of clones; hybridization (crosses between diploids and diploids, triploids and diploids and diploids with tetraploids); chromosome duplication; mutation and transgenic. Methods involving hybridization, however, the method mostly used, is limited by pathernocarpy, sterility, variable number of ploidy levels and low seed production. All varieties produced by the program are then evaluated in banana producing regions in Brazil. Recently new breeding techniques based on genetic information on Musa ssp. are being incremented.

“…Despite enormous difficulties, Musa breeders have managed to produce successful hybrids (Vuylsteke et al 1993;Rowe 1998;Ortiz and Swennen 2014). One of the key steps in the Musa breeding process is the development of agronomically-improved, disease-resistant diploid parental lines (Tenkouano et al 2003), which can be used for producing synthetic tetraploid hybrids (Rowe and Rosales 1996). However, little is known about the exact ancestral genetic basis of domesticated banana cultivars (De Langhe et al 2010), which hampers the choice of suitable parents for crosses to produce new hybrids with plant and fruit qualities comparable to the currently grown cultivars.…”

Molecular and cytological characterization of the global Musa germplasm collection provides insights into the treasure of banana diversity

Bananas (Musa spp.) are one of the main fruit crops grown worldwide. With the annual production reaching 144 million tons, their production represents an important contribution to the economies of many countries in Asia, Africa, Latin-America and Pacific Islands. Most importantly, bananas are a staple food for millions of people living in the tropics. Unfortunately, sustainable banana production is endangered by various diseases and pests, and the breeding for resistant cultivars relies on a far too small base of genetic variation. Greater diversity needs to be incorporated in breeding, especially of wild species. Such work requires a large and thoroughly characterized germplasm collection, which also is a safe depository of genetic diversity. The largest ex situ Musa germplasm collection is kept at the International Transit Centre (ITC) in Leuven (Belgium) and currently comprises
