Abstract

Nine parents and twenty hybrids of rice (Oryza satival.) were evaluated for heterosis for days to flowering, plant height, number of productive tillers, panicle length, number of grains per panicle, 100 grain weight and grain yield. Hybrids showing negative heterosis for flowering duration recorded positive heterosis for yield components. Significant standard heterosis for other traits was also observed. We can expect to develop hybrids from the parental lines possessing carliness for higher yield components.
