Abstract:

Eight F_2 populations of winter wheat hybrids and their parents were space-planted inrandomized blocks with two replications.Heritabilities (in the broad sense) of nine characters,namely,date of heading,plant height,ear length,number of fruiting spikelets per ear,earsper plant,seeds per ear,seed wears per ear,seed weight,and yield per plant were calculatedas the percentage of genotypic variance of phenotypic variance.Date of heading gave the highest heritability,72.04%,and ears per plant the lowest,25.57%.E...
