Genome classification of banana genetic resources of Manipur using morphological characters


Manipur, a northeastern state in India, harbours a rich diversity of both wild and cultivated bananas. The banana cultivars collected from all the districts were carried out for their taxonomic identification and genome group classification. A total of 27 cultivars were collected in the present study. Of all the cultivars, Musa balbisiana clone was represented by 3 cultivars; 8 cultivars were identified under M. acuminata clones. Majority of the cultivars (16) were identified as Musa species, hybrid of M. balbisiana and M. acuminata. Among these cultivars, 3 cultivars were classified under BB genome while 3 cultivars were classified under the AA genome group. The ABB genome group was represented by 13 cultivars. 5 non-seeded cultivars were classified under AAA genome group and the AAB group was also represented by 3 sweet smelling cultivars. The dendrogram constructed based on the 15 morphological characters showed the clustering of cultivars into 3 major groups, at a distance coefficient ranging from 0.60 to 0.50, corresponding to genome groups of the cultivars. The present findings provide the status of existing banana genetic resources from Manipur which could be utilized in improvement and conservation programs.
