Studies on physical fruit characters based selection indices in mango

An attempt was made to construct the selection indices based on genetic merit of fruit characters for fruit yield/tree in 48 genotypes of mango (Mangifera indica L.). Among tested genotypes, SBM 01–35, SBM 01–26, SBM 01-9, SBM 01–10 and SBM 01–26 in on year while, SBM 01–12, SBM 01–36, SBM 01–26, SBM 01–28 and SBM 01-9 in off year exhibited highest fruit yield jtree. Genotypes SBM 01–10, SBM 01–36, SBM 01–09, SBM 01–30 and SRM 01-6 showed comparatively high estimates of selection indices during on year while, SBM 01–36 followed by SBM 01–12, Totapari, SBM 01–17 and SHM 01–29 exhibited the maximum estimates of selection index for fruit yield tree during off year. Alphonso followed by SBM 01-5, SBM 01–13, Langra and SBM 01–14 during on year and Dashehari, Safeda, SBM 01-3 and SBM 01–39 in off year exhibited the minimum estimates of varietal indices. Genotypes differed considerably in ranking pattern of the genotypes based on selection indeces. Genotypes SBM 01-9, SBM 01–10, SSM 01–30, SBM 01-6 and SBM 01–36 showed maximum varietal indices and phenotypic performance in both the years thus, appeared promising for use in mango breeding programme.
