培育耐热品种是小麦育种的重要目标，需要有效的选择方法。在本研究中，轮回选择作为一种策略，以提高小麦的耐热性进行了评估。在位于科英布拉-MG和Vicosa-MG的Universidade联邦de Vicosa的研究领域进行的实验中，在2004年和2007年，在两个生长季节（夏季和冬季）进行了两个周期的轮回选择。遗传增益和变异性的存在表明了小麦耐热性轮回选择成功的可能性。
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 Vicosa, located in Coimbra-MG and Vicosa-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.
