Estimation of variability, heritability and genetic advance for yield and quality characters in bread wheat (Triticum aestivum L.)

Abstract

Fifty genotypes of Bread Wheat (Triticum aestivum L.) were evaluated against four check varieties viz., DBW 187, DBW 222, GW 322, and WB 02 for fourteen different yield and quality characters to study the genetic variability, heritability and genetic advance in Augmented Block Design during Rabi 2021-2022 at crop research farm, BAU, Kanke, Ranchi. The results revealed that highest grain yield per plant attained by GW 2021-1022 (9.45g) followed by QLD 125 (8.79g) and PBS 03 (7.91g). As far as quality parameters is concerned, the maximum protein, iron and zinc content was recorded in BNSR 8 (14.52%), INDB 2119 (53.87 ppm) and PBS 01 (53.79 ppm) respectively. High genotypic and phenotypic co-efficient of variation (GCV & PCV) was recorded for Zinc content and sedimentation value. High range of heritability coupled with high genetic advance was observed for the characters viz., number of grains per spike, spike length, biological yield per plant, sedimentation value, iron content and zinc content.
