Morphological and Agronomical Characterization in Bread Wheat (Triticum aestivum L.) Germplasm and Combined Study of Heritability, Genetic Variance, Genetic Advances and Association of Characters

Abstract

The present experiment was carried out during Rabi 2021-2022 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut-250110 (U.P.). The material used in the present study comprised 103 germplasm accessions of Wheat (Triticum aestivum L.)  having variability for various agronomic and morphological characters were obtained from the available germplasm in the Department of Genetics & Plant Breeding, SVPUA&T, Meerut. The number of genotypes are 103 including four check (DBW-71, DBW-222, DBW-173, HD-3226), the Plot size is10 row 2.5m length spaced at 0.25m and the date of sowing is 20 December, 2021 on Augmented experimental design. Twelve observations were recorded. In each plot, five plants from each genotype were arbitrarily selected and tagged to record the observations studied characteristics except days to 50 % flowering and days to maturity they were recorded on plot basis. The highest value of biological yield per plant was estimated in CSW-18 (45.16g), DBW-621 (51.45%) recorded a high value of harvest index and the maximum grain yield is from CSW-18 (15.94) g. High heritability coupled with high genetic advance observed for gluten content, grain yield per plant, biological yield per plant, harvest index and number of productive tillers per plant.
