Abstract

This study aimed to assess the performance of advanced CIMMYT wheat germplasms for yield and related traits in diverse climatic conditions of Baluchistan. The field trial, conducted during the Rabi season 2022-23 at Agriculture Research Wayaro Farm, Lasbela, employed a randomized complete block design with 14 selected wheat lines. Genotypes G8 and G14 exhibited notable characteristics, such as maximum physiological maturity and spike initiation, respectively. G13 and G5 demonstrated high values for harvest index, grain yield, flag leaf, and grain filling duration, plant height, respectively. Positive correlations were observed among grain yield, spike initiation, harvest index, biological yield, and plant height, while negative correlations were noted between physiological maturity, spike initiation, and grain filling duration. The study suggests integrating high-yielding and long-spiked lines into a recurrent selection program. Further investigations on these genotypes in larger germplasm pools are recommended to evaluate combining ability and stress resistance for potential new variety releases.
