Genetic variability, correlation and path analysis studies for grain yield and morpho-physiological traits under moisture-stress conditions in bread wheat (Triticum aestivum L.) under north-western Himalayan

In order to determine best selection criteria for moisture stress tolerance, thirty-one diverse genotypes including 27 bread wheat lines along with two triticale and one each of durum barley were evaluated assess different components variability, correlation path analysis using various morpho-physiological, grain yield contributing traits in moisture-stress conditions under both field controlled conditions. Analysis variance revealed significant genotypic variation all the studied which indicated presence sufficient genetic variability amongst these traits. Grain per plant, tillers plant harvest index exhibited moderate estimates PCV, GCV, heritability advance while seedling dry weight high PCV GCV coupled advance. Based on analysis, grains spike, biological emerged be important Flag leaf area, peduncle length matter accumulation also appeared based their direct or indirect contributions towards yield. Most showed positive correlations among themselves, but none yield, at maturity.
