Identification of Heat Tolerant Bread Wheat ( Triticum Aestivum L.) Genotypes Through Heat Susceptibility Index (HSI) and SSR Markers

The present study “Identification of heat tolerant bread wheat (Triticum aestivum L.)” genotypes through heat susceptibility index (HSI) and SSR markers” was undertaken by growing 52 genotypes during rabi 2019–20 and rabi 2020–21 in two different sowing conditions (timely sowing and late sowing). Based on pooled results of two years for heat susceptibility index (HSI) and yield stability ratio (YSR), eight genotypes, viz. AKAW 4901, UAS 375, K 1317, WH 1127, HTW 11, WH 1105, HIKK 09 and DBW 14 were identified as heat tolerant genotypes, as these genotypes had heat susceptibility index less than 0.50 and high yield stability ratio (> 83
