Evaluation of genetic variability for yield and associated traits in Wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted during the 2023-24 cropping season at the Research Farm of J.V. College, Baraut (U.P.), affiliated with Chaudhary Charan Singh University, Meerut, to assess genetic variability for yield and its contributing traits in wheat (Triticum
aestivum L.). The study involved 25 genotypes procured from IIWBR, Karnal, and IARI, New Delhi, evaluated in a randomized block design with three replications under highland agro-ecological conditions. Observations were recorded on eleven agronomic traits,
including phenological, morphological, and yield-related parameters. Analysis of variance revealed significant differences among genotypes for most traits, indicating the presence of substantial genetic variability. Traits such as number of tillers per plant, grains per ear, 1000-grain weight, and harvest index showed strong association with grain yield per plant. The results suggest considerable scope for selection and genetic improvement of wheat genotypes for enhanced productivity under similar agro-climatic conditions.
