Genetic Variability, Heritability and Genetic Advance in Durum Wheat (Triticum durum Desf.)

Abstract

The current examination was laid out using 57 durum wheat genotypes at Instructional Farm, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur during Rabi, 2019-2020 in augmented randomized block design with four replication of checks only. Analysis of variance manifested significant difference between genotypes for many character studied, indicating sufficient genetic variability among the genotypes. Phenotypic Coefficient of Variation (PCV) was somewhat higher than the respective Genotypic Coefficient of Variation (GCV) for all the character reflecting that the environment had little effect on the characters. GCV was found higher for the Number of grains per spike, sedimentation value, number of effective tillers per plant and 1000-grain weight while higher values of PCV was recorded for the number of effective tillers per plant, number of grains per spike, sedimentation value and grain yield per plant. High heritability (broad sense) coupled with the high genetic gain was recorded for the traits like sedimentation value (ml), days to 50% heading, number of grains per spike and 1000-grain weight.
