Genetic variability and correlation studies for selection of multiple disease resistance lines in two crosses of peanut

The two F3 populations of peanut were evaluated for multiple disease resistant lines. The analysis of variance revealed sufficient variability in the populations. GAM and heritability estimates were high for all the traits signifying better scope for selection. TG-19 population was superior for Aspergillus seed colonization (13%) and rusts (19%) resistance, where as TG49 was better for the late leaf spot resistance (6%). The results suggested need for large population size, or intermating among selected lines, to combine multiple disease resistance and high yield.
