Identification of donor for seed yield and its attributing traits in pigeonpea [Cajanus cajan (L.) Millsp.]

Abstract

The experiment was undertaken to study on Identification of donor for seed yield and yield attributing traits in pigeon pea. The experimental material consisted of 12 parents vies 7 lines x 5 testers in randomized block design for 12 characters viz. days to flowering initiation, days to 50% flowering, days to maturity, plant height (cm), number of primary branches per plant, number of pod clusters per plant, number of pods per cluster, number of pods per plant, pod length (cm), number of seeds per pod, 100 seed weight (g), seed yield per plant (g) and others components in pigeon pea improvement breeding has been the basic requirement is general combining ability effect. In the present investigation, a wide range of variability observed for nearly all the traits viz. number of pods per plant, days to maturity, number of pod clusters per plant, days to 50% flowering, plant height and seed yield per plant. The studies general combining ability also provides information about the good combiners for pigeon pea breeding program with yield and vigours plant in the expression of various characters.
