“…Molecular markers have been used in assessing the variation and relationships within and among different banana groups. Ortiz and Swennen (2014) indicated that DNA markers can be used as a tool to facilitate taxonomy and assessment of cultivar trueness-to-type. They referred to new microsatellites as being widely used for assessing diversity in bananas, plantains and other related crop wild relatives, some of which derived from expressed sequenced tags (EST) or from genomic sequence surveys (GSS).…”

“…Banana breeding carried out by the International Institute of Tropical Agriculture (IITA) and the National Agricultural Research Organization (NARO) targets constraints related to pests and diseases (Tushemereirwe et al 2015). Banana crossbreeding starts with the hybridization of EAHB with wild or improved diploids which have resistance to banana diseases and pests, to generate banana clones showing host plant resistance to biotic and abiotic stresses, short cycle and height, high yield and quality (Ortiz and Swennen 2014). To facilitate the access and use in Musa breeding, appropriate conservation, characterization and evaluation of genetic variation in the matooke banana cultigen pool is required.…”

Morphological traits are commonly used for characterizing plant genetic resources. Germplasm characterization should be based on distinctly identifiable, stable and heritable traits that are expressed consistently and are easy to distinguish by the human eye. Characterization and documentation of a representative sample of East African highland bananas (Lujugira-Mutika subgroup) was carried out following an internationally accepted standard protocol for bananas. Eleven cultivars were characterized using an existing set of minimum descriptors (31 qualitative and quantitative traits) with the aim of determining stable descriptors and the ability of these descriptors to distinguish among East African highland banana cultivars. There was variation in stability of these descriptors within cultivars and across the 11 cultivars. Only 10 (32%) out of 31 descriptors studied were stable in the 11 cultivars. However, they had similar scores and therefore are not suitable to distinguish between cultivars within this group. Nonetheless, these 10 descriptors may be useful for distinguishing the East African highland bananas as a group from other groups of bananas. A few descriptors were unique to the cultivar 'Tereza' and may be used to distinguish this cultivar from other 'matooke' cultivars. None of the quantitative descriptors were stable.

“…Currently, large plantations manage these threats with massive amounts of agrochemicals, creating economically and ecologically unsustainable growing conditions; while smallholders often use improperly characterized local cultivars and mostly cannot afford large investments into agrochemicals. Breeding new and resistant cultivars is hampered by virtual seed sterility of cultivated clones (Ortiz and Swennen 2014). Most of the modern cultivars are believed to have originated from natural inter-and intraspecific crosses of wild AA and BB diploids (2n = 29 = 22) derived from Musa acuminata Colla (with genome A, D 'Hont et al 2012) and M. balbisiana Colla, respectively (with genome B, Davey et al 2013).…”

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

“…It ranks as the fourth major crop in tropical and subtropical countries and widely grown fruit in the world (Rahman et al, 2013). Most of bananas varieties are polyploids, thus have a complex genetic structure (Ortiz & Swennen, 2014). Bananas are considered as a source of energy and have lots of health benefits.…”
