Genetic Variability for Yield and Yield Component Traits in Advanced F<sub>3</sub> and F<sub>4</sub> Generations of Pigeonpea (<i>Cajanus cajan</i> L.)

Abstract

The present investigation aimed to study genetic variability generated from the Gulyal white X Maruti cross in F 3 and F 4 generation to make effective selections for improving productivity. The study indicated that the higher magnitude of variability were recorded in F 3 and F 4 generation for 50 per cent flowering, number of secondary branches, number of seeds per pod, number of pod per plant, seeds yield per plant and seed yield (Kg/ha) and moderate variability observed in pod bearing length and test weight (gm). The higher heritability and genetic advance per mean were recorded in F 3 and F 4 generation for 50 per cent flowering, number of secondary branches, number of seeds per pod, number of pod per plant, seeds yield per plant and seed yield (Kg/ha) that implicate additive gene action in inheritance of these traits thus phenotypic selection would be effective in yield improvement .
