Abstract

The development of triticale (X Triticosecale Wittmack) cultivars which are tolerant to drought and heat stress is an objective in many breeding programmes, but so far success has been limited. This study was conducted to determine the susceptibility index (S) of triticale under stress conditions. Twenty genotypes were grown in replicated trials and evaluated for heat and drought tolerance under natural conditions at Adana, Turkey, from 1992 to 1996. Among the advanced lines of triticale, genetic variation for adaptation to heat and drought conditions—typical features of the Mediterranean environment—was determined. The best yielding lines under stress, hence having a low susceptibility index, were Lynx/Yogui and Zebra 31. The implications of these findings for triticale breeding in stress environments are discussed
