Genetics of yield and related traits in bread wheat over different planting dates using diallel analysis

-1 , number of grains spike -1 , grain yield plant -1 and 1000-grain weight. The experiment was planted in randomized complete block design in three replicates. F-test declared significantly different means for all traits. Analysis of genetic components revealed significant additive (D) and dominant (H) genetic variations for days to heading, productive tillers plant -1 , number of grains spike -1 , grain yield plant -1
