CGMS-restoration system and grain yield of introduced F₁ hybrids and the home-bred ones in Japonica rice were comparatively studied. It was found that CGMS-restoration system was indentical with each other. Maximum standard heterosis for rough rice yield of introduced F₁ hybrids and the home-bred ones compared with Nagdongbyeo (703.8kg/10a) were 18.8% and 21.9%, respectively. The path coefficients of yield components to yield of introduced F, hybrids and the home-bred ones were the highest in the filled grain ratio and in the gains per panicle, respectively.
