The present was carried out on "Genetic analysis of yield component traits in rice. Diallel analysis was carried out based on the method I and model I as suggested by Griffing. Seven economically important yield components traits were evaluated based on per se performance, general and specific combining ability effects, gene action and heterosis. The cross ADT 36 × ADT 37 and ASD 16 × ADT 36 exhibited highly significant sca effects and highly significant heterosis for grain yield and for most of its yield component traits. Hence, these crosses can be exploited for heterosis breeding provided...
