Identification of New Promising F1 Hybrids in Rice with Emphasis on Yield Attributing Traits
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2019, Vol 12, Issue 1
Abstract
Success and sustenance of hybrid rice technology exclusively depends on the exploitation of heterosis in F1 generation. An experiment was carried out to evaluate the performance of newly developed twenty five (25) F1 hybrids based on IR 58025A by comparing with hybrid and Inbred checks with special emphasis on yield attributing traits. Highest yield (Square meter) was observed by Arize 6444 Gold (0.987 Kg), followed by INDAM 200-017 (0.945 Kg), PRH 8005 (0.938 Kg), JKRH 3333 (0.928 Kg) and PRH 8007 (0.927 Kg) respectively. Among the tested F1 Hybrids PRH 8005 and PRH 8007 were identified as promising by emphasis on yield. PRH 8007 was identified as early maturing Hybrid among the tested materials. Analysis of variance reveals that varietal differences are signified and wide variability present among the genotypes with respect to all the characters. The results clearly indicate that the hybrid rice technology can take part a pivotal role to augment the rice productivity.
