Relationship between canopy temperature depression, membrane stability,relative water content and grain yield in bread wheat (Triticum aestivum)under heat-stress environments

A study was conducted during winter (rabi) of 2006–08 at New Delhi using 49 diverse wheat (Triticum aestivum L. emend. Fiori & Paol) genotypes and three sowing dates (15 November, 15 December and 5 January) to assess the relationship of physiological parameters with grain yield under hot environment. From the analysis of normal, late and very late sowing date, it is evident that all the characters are showing sufficient amount of variability in...
