摘要： Identification of stable and high yielding varieties under different environmental conditions prior to release as a variety is the major steps for plant breeding. Eight promising wheat genotypes were evaluated against two standard checks across five locations under terminal heat stress condition. The experimental design was an RCBD with three replications in over one year. AMMI analyses exhibited significant (p<0.01) variation in genotype, location and genotype by location interaction with respect to grain yield. The ASV value revealed that GEN4, GEN9, and GEN8 were stable, while GEN5, GEN1, and GEN6 were the most sensitive genotypes. The GGE results also confirmed GEN3, GEN7, GEN8, GEN9 and GEN4 were the most stable cultivars. Five distant mega-environments were identified including Dinajpur and Jamalpur with GEN3, GEN7 and GEN8 as the most favorable, Joydebpur, Rajshahi and Jessore with GEN4 and GEN9 as the most favorable. Genotype GEN7 and GEN8 showed highly resistant to BpLB, GEN3 and GEN4 showed moderately resistance to BpLB, and GEN9 showed moderate susceptible to BpLB. On the other hand, these five genotypes performed resistance to leaf rust. The genotype GEN7 (BAW 1202) was released as BARI Gom 32. Considering all analysis, GEN3 (BAW 1194), GEN7 (BAW 1202) and GEN8 (BAW 1203) demonstrated more stable genotypes with high mean yield, resistant to BpLB and leaf rust. Thus it is indicated that these genotypes can be used as suitable plant material for future breeding programs.
