Abstract:

An investigation was taken up to study the magnitude of heterosis for nine characters in rice viz., days to 50 percent flowering, days to maturity, plant height at maturity, productive tillers per plant, tillers per square meter, thousand grain weight, grains per panicle, and yield per plant. The base material for this experiment consisted of 36 F1s involving three cytoplasmic male sterile lines (CMS) and twelve diverse restorers in line x tester mating design along with best varietal check Phule Samruddhi and best hybrid check Sahyadri-4. Hybrids were evaluated in randomized block design (RBD) with three replications. Heterosis over mid parent, better parent and standard checks revealed that experimental hybrids had higher heterotic effect for all the characters under study. Majority of hybrids exhibited negative heterosis for days to 50 per cent flowering, days to maturity. An appreciable amount of heterosis was observed in yield and yield contributing characters. Thus, the hybrids RTN17-A x VDN-1335 for earliness and IR58025-A x VDN-1425, RTN13-A x VDN-1606 and RTN13-A x VDN-1608 showed high per cent of heterosis over check, which can be exploited on commercial basis.
