Identification of superior parents and hybrids for improving pigeonpea


Crop Improvement 23(1): 66-70
Identification of superior parents and hybrids for improving pigeonpea
A study involving three male-sterile lines and 11 diverse pollinators of pigeonpea exhibited preponderance of additive genetic effects for plant height, number of primary and secondary branches and pods per plant; non-additive gene effects for days to flowering and maturity, seeds per pod and 100 seed weight; and equal importance of both additive and non-additive gene effects for pod bearing length of the main stem and grain yield per plant. PMS1, a determinate male sterile line was a good combiner for earliness, number of secondary branches, pod bearing length, pods per plant and grain yield. Three top yielding hybrids, PMS 1 times AL 688, ms Prabhat (DT) times AL 101 and ms Prabhat (DT) times AL 259 depicted highest SCA effects for seed yield and out yielded the check hybrid PPH 4 by a margin of 67.9, 34.9 and 17.5 percent respectively.
