Genetic Variability and Association Studies in Wheat

The field experiment was conducted at Genetics and Plant Breeding Research Farm Narendra Deva University of Agriculture and Technology Faizabad. The experimental material comprised of 140 exotic and indigenous lines of bread wheat along with three checks were evaluated in partially reclaimed salt affected soil under late sown and irrigated conditions during Rabi 2010-11 in Augmented Block Design having 7 blocks of 23 plots each. The characters studied were Flag leaf area days to maturity plant height No. of reproductive tillers per plant spike length peduncle length grains per spike 1000-grain weight biological yield per plant harvest-index grain yield per plant flag leaf angle leaf blight (double digit system). The data on 13 characters was utilized for estimation of mean range and least significant differences correlations path-coefficients and genetic divergence. The genotypes 29th ESWYT-130 42nd IBWSN-1158 27th SAWSN-3107 EC-664236 EC-634300-110 IC-524282 and 19th HRWSN-2026 produced higher grain yield per plant.The field experiment was conducted at Genetics and Plant Breeding Research Farm Narendra Deva University of Agriculture and Technology Faizabad.
