To evaluate different bread wheat cultivar in the Heat of the end of the season, agricultural experiment in the veys area 10 km East of Ahvaz, split plot in randomized complete design with 4 repeat was conducted. The main factor of this experiment include, good planting date (15 azarmah) and delay the planting (20 deymah) and the sub factor of this test, genotypes (38 pcs) where considered.Delay Planting date was considered the plant will end with the heat of season. In this experiment yield and yield component, the STI tolerance index was also estimated by Fernandez as a criterion for measuring end-season heat stress tolerance in 38 genotypes. Varieties of Chamran, bayat, and also Arvand Rud has the highest STI in among 38 genotypes to studied. Varieties of Chamran, bayat, Arvand Rud, virginia, plateau and-78-11 genotypes bearing the name of thermal stress. Other genotypes where evaluated according to stress tolerance index and previous report result sensitive genotypes were called. Totally in Khuzestan provinceIf the selection of suitable varieties and possibility of optimal agriculture processing are carried out. Can be cultivated with tolerance varieties, while maintaining high performance, it improves the sustainability of production.
