Abstract:
The present study was carried out to estimate the nature and magnitude of heterosis for grain yield and its attributing traits through 9 x 9 diallel mating design along with nine inbreds and one standard check, viz., Phule Aadishakti in pearl millet. The experiment was laid out in Randomized Block Design with three replications. The analysis of variance revealed that there were significant differences among the parents and crosses for all the characters studied. The magnitude of heterosis varied from cross to cross for all the characters studied. Maximum positive heterosis for grain yield per plant over better parent and standard check (Phule Aadishakti) was observed to be 69.66 and 32.76 percent, respectively. Considering the heterosis DHLBI-1708 x DHLBI-181138, DHLBI-1708 x DHLBI-18963 and DHLBI-181181 x DHLBI-181138 appeared to be the more promising hybrids for breeding.
