Abstract

One hundred diverse genotypes of groundnut were evaluated for 15characters in order to construct selection indices. The characters, which had desirable correlation as well as moderate to high direct effect on pod yield per plant were considered as selection index criterion. The pod yield per plant (X1) along with its five components viz., days to maturity (X2), number of pods per plant (X3), kernel yield per plant (X4), biological yield per plant (X5) and harvest index (X6) were utilized for the construction of selection indices. The discriminant function had higher genetic gain and relative efficiency over straight selection for pod yield alone. The relative efficiencies of selection indices constructed in combinations of two or more characters were ranged from 105.90 to 536.06%, while genetic advance ranged from 12.75 to 64.58g. There was an increase in genetic gain and relative efficiency with inclusion of an additional trait in the character combination. A selection index consisting of pod yield per plant, days to maturity, number of pods per plant, kernel yield per plant and biological yield per plant and an index involving pod yield per plant, number of pods per plant, kernel yield per plant and biological yield per plant registered higher genetic gain and relative efficiency. These indices could be advantageously exploited in the groundnut breeding programmes for isolating high yielding genotypes.
