Abstract

The present study was carried out with the objective to assess the genetic variability among parent and hybrid association between grain yield and its quantitative and qualitative traits, which is essential to know the effectiveness of selection for simultaneous in these traits. The material consisting of 67 genotypes (19 parent and 48 crosses) of wheat was grown in complete randomized block design with three replication during rabi season. The high PCV and GCV were recorded for grain yield per plant followed by peduncle area, productive tiller per plant, biomass of the plant and grain filling period. High heritability with high genetic advance as per cent of mean was observed for productive tiller per plant, peduncle area, biomass of the plant and grain yield per plant. Grain yield per plant showed significant and positive association with productive tiller per plant, spike area, grain weight per spike, 1000 grain weight and biomass of the plant. Hence, main emphasis should be given on grain yield in breeding programme.
