Field Environment Genetic Variability and Association Analysis in Madhuca Indica Gmel.

Abstract

Twenty genotypes of Madhuca indica Geml. distributed over different sites/locations of district Allahabad and adjoining areas in Uttar Pradesh, in their natural range were investigated for the pattern of field environment genetic variability and association analysis in Madhuca indica. The results revealed, higher values for phenotype coefficient of variation as compared to genotypic coefficient of variation in corresponding germination and seedling growth characters, indicating that the characters are greatly influenced by the field environment. The heritability and expected genetic gain were also observed to be high to moderate for these characters. There is wide scope for early screening of the genotypes because of the positive and significant correlation at 5% level of significance among germination and seedling growth characters with each other except for few characters times with each other such as internodal length with number of leaves per seedling, number of leaves with dry weight of shoot, fresh weight of root and total biomass of seedling. Respectively as such genotypes S20, S12, S9 and S19 showed good performance as compared to other genotypes and are recommended for further genetic improvement programme in this species.
