Genotypic Performance of F_4:7 Wheat Lines under Irrigated and Rainfed Conditions

Abstract

Wheat (Triticum aestivum L.) is an important crop also known as the king of cereals and consumed as a staple crop by one-third of the global population. However, wheat production under rainfed conditions is restrained by water scarcity. The experiment was conducted to evaluate wheat breeding lines for yield. Fifteen F 4:7 bread wheat lines along with two check cultivars Tatara and AUP-5008 were tested in RCB design in three replications under irrigated and rainfed conditions. Analysis of variance showed significant (p<0.01) differences among the genotypes for days to heading, plant height, spike length, grains spike -1 , grain weight spike -1 , 1000-grains weight and grain yield while nonsignificant for rest of the traits. Genotype by environment (GE) interaction was significant (P<0.05) for grain yield and non-significant for the remaining traits.1000-grains weight showed positive significant
