HETEROSIS IN INTER-VARIETAL HYBRIDS OF RICE (Oryza sativa L.)
Madras Agricultural Journal1989Vol. 76(september), pp. 507–511
Abstract
The extent of heterosis for yield components in a set of fourteen intervarietal rice hybrids involving thirteen parents were studied. Substantial heterosis over mid-parent and better parent was observed for the fourteen characters studied. The hybrid Vaigai/IET 4786 was superior with high heterosis for boot leaf area, ear bearing tillers, grains per panicle, grain yield and strau yield.
