Abstract

                                Thiry six hybrids were developed utilising three cytoplasmic genetic male sterile lines (V 20 A, IR 58055 A and IR 62829 A) and twelve testers and they were studied for the extent of heterosis on six quantitative characters viz., days to flowering, panicles per plant, grains per panicle, spikelet fertility. 100- grain weight and grain yield per plant. The hybrid IR 62829 A x CO 37 revealed heterotic vigour for panicles per plant and grain yield per plant.

Key words : Hybrid Rice, Heterosis
