Yield and nutrients content of two contrasting (Spring and Winter) crossed ecotypes of wheat

摘要

Two divergent ecotypes of five winter wheat were crossed with ten spring wheat lines in line × tester fashion. EC609406 and EC609396 were identified as good general combiners for grain yield per plant, 1000- grain weight, reduced days to heading and yellow rust resistance. Among the spring wheats, HD3096 was found to be a good general combiner for yield, yellow rust resistance, 1000-grain weight, Fe content and early heading. Cross EC609412/PBW590 had significant and desirable SCA effect for gain yield per plant, early heading and yellow rust resistance whereas cross EC609406/HD2967 had significant SCA effect for Fe content and 1000-grain weight with negative SCA for yellow rust resistance. Cross MvEmese/HI1562 and EC629405/HD2967 showed significant positive SCA effect for Zn content and early heading.
