The north-eastern region of India including Nagaland is home to many indigenous Musa cultivars and wild/semi wild species. Many of the Musa species are extensively found in different agro-climatic condition and are widely distributed in northeast region of India, which has been primarily considered as the richest sources of natural banana diversity. The experiment was carried out in the Department of Horticulture, School of Agricultural Science and Rural Development, Nagaland University during the year 2019-2021. A total of twenty banana genotypes which include both wild and edible banana were considered for the study and the data was recorded in situ from different banana growing region covering fifteen villages spreading across five revenue districts of Nagaland. The genetic and phenotypic coefficient of variation, heritability and genetic advance were estimated for fourteen characters which included number of suckers, girth size, pseudo stem height, leaf blade length, leaf blade width, petiole length, bunch weight, number of hands/bunch, number of fingers/hand, fruit weight, pulp weight, weight of peel, fruit peel thickness and pulp: peel ratio. The analysis of variance indicated that the mean sum of square due to genotypes were highly significant for all the quantitative characters. Significant means sum of square due to fruit yield attributing characters revealed existence of considerable variability in material studied for improvement of various traits. Highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was observed for bunch weight indicating selection for such characters would be more reliable to be used as selection for crop improvement. High degree of heritability estimates were obtained in case of fruit weight, pulp weight, girth size and weight of peel. High genetic advance were observed for leaf blade length and pulp weight indicating predominance of additive gene effect and possibilities of effective selection for the improvement of these characters.
