Résumé
The present investigation was carried out to study heterosis and combining ability estimates and their interaction with environments (normal and stress irrigation treatments). The breeding materials used herein included eight parents Ib. 4, Ib.2 , L9 , L22 , Sakha 93, M37, M45 and Giza 168. In the first season 2012/2013, the eight parents were grown at various planting dates in order to overcome differences in time of heading. All possible parental combinations without reciprocals were made among the eight parents. In the second season 2013/2014 the eight parents and their twenty eight possible F1 crosses were sown on 25th Nov. 2013, in RCBD with three replications. The normal irrigation traits (E1) and the second experiment was irrigated once after planting irrigation (E2) (stress). Each plot consisted of one ridge ; three meters long with 60 cm between ridges and plants within ridge were 20 cm apart. The dry method of planting was used in this concern, the other cultural practices of growing wheat were properly practiced. Data were recorded on five individual plants randomly sampled from each plot for growth yield and yield components and biological yield/ plant.
