Effect of terminal heat stress on genetic responses of biochemical and yield contributing parameters in wheat Triticum aestivum L

Abstract

Heat stress is a matter of a great concern for the wheat crop. Breeding of heat-tolerant cultivars requires knowledge of the genetic behaviour of morpho-physiological traits. Genetic analysis through Generation Mean Analysis helps to find out the nature of gene actions involved in a concerned trait by providing an estimate of main gene effects (additive and dominance) along with their digenic interactions (additive × additive, additive × dominance, and dominance × dominance. newline
