Genetic Merit Based Genotype Selection for Physical Fruit Traits in Mango
2014
Arun Kumar Barholia | Sangeeta Yadav
Selection indices based on their genetic merit of fruit characters were constructed for fruit yield/tree in 48 genotypes in mango (Mangifera indica L.). 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 recorded highest fruit yield /tree. Genotypes SBM 01-10, SBM 01-36, SBM 01-09, SBM 01-30 and SBM 01-6 exhibited comparatively high estimates of selection indices during on year while, SBM 01-36 followed by SBM 01-12, Totapari, SBM 01-17 and SBM 01-29 showed 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 their ranking pattern based on selection indices. Genotypes SBM 01-9, SBM 01-10, SBM 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 as parent in mango improvement programme.
