Response of wheat varieties to heat stress under elevated temperature environments

Year: 2017

Type: article

Abstract: A field experiment was conducted during winter (rabi) season of 2014-15 at IARI, New Delhi to evaluate the response of wheat varieties to heat stress. Three wheat varieties (HD 2967, WR 544 and HD 2985) were grown under ambient and elevated temperature (1.9 to 3.4 oC more than ambient during crop season) condition. Results indicated that the variety WR 544 is highly resistant to heat stress as it exhibited stability of leaf area index (LAI), photosynthesis (Pn), grain yield, harvest index (HI) and test weight under elevated temperature. However, HD 2967 recorded more yield but WR 544 performs better in elevated temperature conditions.
