Characterization of Six Varieties of Banana (Musa paradisiaca L.) Grown in Sarpang Dzongkhag

AUTHOR: Chinta Mani Dhimal, Tulsi Gurungw Ngawang 

ABSTRACT

Twelve local banana (Musa paradisaica L.) varieties are popularly cultivated in Sarpang Dzongkhag but lack proper information on their characters. Therefore, evaluation on their morphological and compositional characters of six commonly grown varieties was conducted in Hilley and Shompangkhag geog under Sarpang. The purpose of the study was to identify morphological and compositional characters that have relationship and differences among six banana varieties. Using quantitative characters, through cluster analysis, they were grouped into four. Significant difference was observed in pseudo-stem height, pseudo-stem diameter, leaf blade length, leaf blade width, peduncle width, number of fingers per hand, finger length and finger weight. No significant difference was observed in bunch weight among six varieties. Peduncle length was similar among the varieties. Bunch weight was correlated with peduncle width and number of fingers per hand. Qualitative characters related to leaf, growth habit, bunch, rachis, male bud, bracts, male flower and fingers were observed. Dhusrey had generally different characters compared to other varieties. Through cluster analysis on compositional characters, they were grouped into two. Significant difference was observed in pulp pH and dry matter content while no difference was found in TSS, ash and protein content among six varieties. Compositionally Jhaji had comparatively different characters while others were similar.
