Abstract: The experiment was conducted during 2019-2021 at Regional Agricultural Research Station, Akbarpur, Moulvibazar, Bangladesh with twenty-three local mango genotypes to assess the performance and genetic divergence for the identification of suitable parents for the futute breeding program. . Wide variations were observed regarding the number of fruits/plant, fruit weight, percent of edible portion, and TSS of different germplasms. The highest number of fruit per plant (610) was observed in MIAkb001, highest individual fruit weight /plant (759.7g) was obtained from MIAkb015. The higher fruit yield was recorded from MIAkb001 (162.07kg). The percent of the edible portion was higher in MIAkb014 (65.71%) whereas maximum TSS (18%) was obtained from MIAkb007 andMIAkb015 respectively. The genetic divergence was assessed in 23 mango genotypes through multivariate analysis. The genotypes under this study were grouped into five clusters and the diversity was influenced by the morphological characters. The highest number (8) of genotypes were in cluster-I and the lowest (1) number of the genotype was in cluster-III. From the PCA we found, the number of fruits per plant (FNPP), fruits yield per plant (FYPP), and individual fruit weight were positive across the two axes, and these were the main traits for genetic divergence.
