摘要

Ten F₁ hybrids of rice (Oryza sativa L.) were synthesized using 14 parents and studied the extent of heterosis for plant height, panicles per plant, panicle length, grains per panicle, 1000-grain weight, panicle exertion, flag leaf area, spikelet fertility, kernel L/B ratio and grain yield per plant. Most of the hybrids expressed hybrid vigour for yield contributing traits. The best performing F₁ hybrid ASD 18 x ADT 36 showed maximum heterosis and heterobeltiosis for yield. The hybrids ASD 16 x ADT 30, ASD 18 x ADT 36 and ADT 39 x ASD 18 showed more than 20% of heterobeltiosis for grain yield. The entry ASD 16 x ADT 30 showed high inbreeding depression for most of the yield traits.
