Abstract:
A field study was conducted at Research cum Instructional Farm, S.G. College of Agriculture and Research Station, Kumhrawand, Jagdalpur, IGKV, Raipur (C.G.), in Rabi -2020, in a Randomized Block Design with 2 replications to evaluate 21 accessions of wheat (Triticum aestivum L.). The observations of 8 qualitative and 13 quantitative characters were recorded at different stages of plant growth from flowering stage to harvest, according to the Guidelines for the test of DUS on wheat by PPV& FRA, Government of India. The genotypes exhibited wide range of variation for all the traits except. Genetic coefficient of variation ranged from 4.39 for days to 50% flowering to 32.81 for seed yield per plot. All the traits exhibited high heritability, however very high values of heritability were observed for seed yield per plot (90.88%), harvest index (88.33%) and flag leaf length (87.09%). The traits grain yield per plot and fodder yield per plot showed high heritability and genetic coefficient of variation along with high genetic advance. Therefore, these traits could be considered as suitable selection criteria to develop high yielding genotypes with high sedimentation value. Thus, these characters may be effective as selection indices during breeding programme for improving grain yield and quality.
