Abstract
Twenty six hexaploid triticale (X Triticosecale Wittmack) X bread wheat (Triticum aestivum L. em Thell) derivatives, along with 2 bread wheat and 2 triticale checks, were grown in normal and P-stress environments. Spikes/plant and grain yield/plant, followed by peduncle length, Were the most sensitive to phosphorus deficiency, which also caused a delay in heading and maturity. The heritability and genetic advance for grain yield/plant were high in the stress environment, reflecting the effectiveness of direct selection. The 1000-grain weight, grains/spike and plant height were the important traits for phenotypic selections in both the environments.
