A diallel analysis of 36 F1 and 36 F2 progenies hybrids along with nine divergent parents were estimated. The general and specific combining ability for selection of potential parents and crosses and to ascertain the nature of gene action operating in inheritance of some important quantitative characters associated with shoot fly resistance. These 36 hybrids were developed by crossing nine diverse parents in rabi 2011-12. The results indicated that, IS 18551, IS 2312, SPV 504, Ringni and AKSV 13R showed desirable gca effect for most of the shoot fly resistance traits in F1 and F2 diallel progenies. Crosses exhibiting highest positive significant sca effects for almost all the shoot fly resistance traits included CSV 18R X IS 18551, Ringni X AKR MS45B and IS 2312 X IS 18551 in F1 and F2 diallel progenies. So these crosses may be forwarded further to develop genotypes with shoot fly resistance.
