ABSTRACT -
The development of heat-tolerant varieties is an important goal of wheat breeding programs, requiring
efficient selection methods.
In the present study the use of recurrent selection was evaluated as a strategy to improve heat
stress tolerance in wheat.
Two cycles of recurrent selection were performed in experiments conducted in research areas of the
Universidade Federal de Viçosa, located in Coimbra-MG and Viçosa-MG, in 2004 and 2007, in two growing seasons (summer and winter).
The genetic gain and the existence of variability show the possibility of successful recurrent selection for heat tolerance
in wheat
