Evaluation of barley (Hordeum vulgare L.) genotypes for yield and yield attributing traits in Vindhyan Region of Uttar Pradesh

Abstract

The present study at Field Experimentation Centre, Department of Genetics, SHUATS, Prayagraj during Rabi season of 2023-24 evaluated 20 Barley genotypes, including one check variety, for genetic variability, heritability, genetic advance and correlation. Twenty-three quantitative traits were analyzed, showing significant variation among genotypes. The highest yielding genotypes per plant in six row barley are IBT-51 (1.86 t), IBT-2 (1.80 t), IBT-31 (1.79 t), IBT-52 (1.73 t), IBT-25 (1.71 t), The highest yielded genotypes in two row barley among 6 genotypes are IBT-47 (1.48 t), IBT-20 (1.31 t), IBT-79 (1.31 t), IBT-72 (1.01 t), IBT-69 (0.99 t). The genotypic coefficient of variation was higher than the phenotypic coefficient of variation, with minimal differences between the two. GCV (%) values ranged between least of 0.70 (days to maturity) to a highest value of 32.74 (Grains per spike). PCV (%) followed a similar pattern had a range of 0.90 (days to maturity) to 32.84 (Grains per spike). The genotypic correlation coefficients for nearly all features surpassed the corresponding phenotypic correlation coefficients.
