Performance and yield stability of doubled haploid population wheat (Triticum aestivum L.) under high temperature regime. Abstract India, the second most populated country largest producer worldwide, is vulnerable to global warming especially heat stress. In present investigation, derived from PBW343/IC252478 cross was characterized for various phenotypic morpho-physiological traits subjected analysis stress conditions. These lines were planted on a single location i.e., Agricultural farm Rajendra Prasad Central University, India two successive seasons 2017/2018 and, 2018/2019 three different sowing dates (Controlled or timely, late very sown conditions). Here, preferred this study because it represents hotspot production major constraint grower inclining The alpha lattice design used current investigation with replicates. overall objective identify ideal double heat-stressed results revealed that had significant adverse impact all considered contributed losses about 50%. Stability measurements, genotype × environment interaction (GGE), useful tools determine (heat stressed condition) condition (terminal stress). Therefore, in ranking genotypes both mean performance across six environments, DH 71, 150, 64, 138, 98, 84, 62, 104, 74, 3, 107 & 156 ranked closest genotype, these highly adapted, stable, tolerant yielding indicating them as desirable out 167 studied. Hence, physiological SPAD index (Soil plant development) Canopy (CT) can be effectively screen line tolerance. addition, stable identified could future breeding programs.
