Identification of parents and hybrids for yield and its components using line x tester analysis in rice (Oryza sativa L.)

Abstract

Combining ability analysis for yield and its component traits was carried out in rice through line x tester analysis of 20 
hybrids developed by crossing 5 females with 4 male lines along with parents and checks at Agricultural Rice Research 
Station, Nellore, ANGRAU, AP during kharif 2014. The estimates of gca effects indicated that, among females, BPT 5204 
and among males IR 64, were good general combiners for grain yield per plant. High sca effects were observed in the 
crosses, WGL 48684 x IR 36 and RNR 2465 x IR 36 and they were found to be best combinations for grain yield per plant.
