Heat susceptibility index

High temperature is a major environmental stress factor limiting wheat (Triticum aestivum L.) productivity. Improvement of heat tolerance in wheat is an important breeding objective. The present investigation was carried out to evaluate and identify terminal heat tolerant bread wheat genotypes on the basis heat susceptibility index.

The study was under taken to compare genotypic differences in respect of several fatalities due to high temperature in summer seasons compared to winter for selecting superior heat tolerant tomato genotypes suitable for both the seasons.

A study was conducted at Wheat Breeding section, RPCAU, Pusa, Samastipur, Bihar during rabi 2016-17 to evaluate the genotypes of bread wheat (Triticum aestivum L.) for terminal heat tolerance. Observations were recorded on plant height, number of tillers per plant, flag leaf area, days to fifty per cent flowering, canopy temperature, relative water content, spike length, number of grains per spike, spike fertility, chlorophyll content, days to maturity, thousand grain weight, harvest index, yield per plant, thousand grain weight susceptibility index and heat susceptibility index.

In bread wheat (Triticum aestivum L. em. Thell.), development of thermal stress tolerant cultivars and realization of potential at yield in hot climate is enshrined goal of our breeding program. By keeping the above fact in view, the present study was conducted in two environments i.e. normal and late sown condition with 10 diverse genotypes, their 45 F1’s and F2’s to magnify the yield level of wheat in high temperature areas by selecting stress tolerant parents and cross combinations.
