- Abstract
Seven diverse wheat genotypes were selected and crossed in all possible combinations to study the inheritance pattern of dry matter partitioning traits under normal and drought conditions. The F1 hybrids along with their parental accessions were evaluated under field conditions with three replications following completely randomized block design under both water regimes. Data regarding biological yield plant-1, grain yield plant-1 and harvest index were recorded. Significant genotypic differences were observed among genotypes for the traits under study. The scaling test revealed partial adequacy of the data for all the traits under both water regimes except grain yield plant-1 under drought condition where it was found fully adequate. All the traits exhibited additive type of gene action with partial dominance under both regimes. Moderately high estimates of heritability were recorded. Early generation selection through pedigree or modified pedigree method was suggested for the traits controlled by additive gene action.
