Resumo: Heat is one of the major abiotic stresses that affect wheat yield and quality in many parts of the world. To overcome this problem, the development of heat tolerant cultivars has been shown to be one of the main targets of breeding programs, especially for the conditions of Central Brazil. The present study was developed with objective of identifying promising populations for tolerance to heat stress, in order to obtain lines adapted to the conditions of Central Brazil. The experiment was carried out in the summer of 2011 in Coimbra/MG where 36 segregating populations with different numbers of families per population were evaluated in an augmented block design, determining the cycle, plant height and grain yield. Genetic variability for heat tolerance was observed among the wheat populations. The vegetative development stage of wheat was more sensitive to the effect of heat stress. The most promising segregating populations were IAC364/BRS207, IAC24/Aliança IAC24/Pioneiro that associated high yield with a large number of families selected among the most productive, demonstrating the possibility of selecting heat stress-tolerant lines.
