Abstract

Wheat (Triticum aestivum L.) is a staple crop that feeds hundreds of millions of people, but global climate change is predicted to reduce wheat yields by 6% for every 1°C increase in temperature. The estimation of genetic parameters that avail to decide breeding strategies may vary with environmental conditions, so it is critical to conduct studies in various environments. An experiment was conducted to evaluate the performance of 48 genotypes of wheat under two environments i.e. timely and late sown conditions, for assessment of mean performance, variability, correlation, and path analysis of 16 morpho-physiological traits at research area of Wheat and Barley Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during Rabi 2019-20. The results showed that estimates of phenotypic variance were higher than their corresponding genotypic variances, indicating the influence of the environment. High heritability associated with high genetic advance was reflected for CTD 1 an
