Genetic evaluation of different genotypes of wheat (Triticum aestivum L.) in normal sowing condition in Punjab
Study was carried out with 25 wheat genotypes at Agricultural Research Farm, School of Agriculture, Lovely Professional University, Phagwara, Punjab (India) during Rabi 2017-18 to study genetic variability for 11 traits. The genotypes exhibited broad range of diversity, which means that existence of enough genetic variability in the genotypes under study. High heritability combined with high genetic advance was recorded for harvest index (27.77%) and number of grains per plant (26.31%), which means that this traits were covered by additive gene action and can be effectively used for genetic advancement programme The correlation coefficients estimate exhibit high genotypic and phenotypic correlation for harvest index, number of grains spike-1 and effective tillers plant-1 with grain yield. Outcome of path analysis confirmed that harvest index and grain yield plant-1 should be taken into consideration during wheat improvement programmes. In D2 analysis 25 wheat genotypes were arranged into 6 groups. The genotypes included in group II were recorded minimum days to maturity and days to 50% flowering. Group IV shown high harvest index and grain yield-1 which appeals that the genotypes present in these groups could adequately used for the wheat advancement programmes
