The number of days with freezing temperatures in October, November, December, January, February and March were recorded as 3, 0, 4, 17, 20 and 18, respectively. The lowest temperature in the middle of February in 1997 was 12.1 C. While susceptible mutants were generally killed due to cold damage, the mutants 2200210, 2200286, 2300011, 2400106, 2400107, 3500016, 4200230 and 5200132 were identified as cold tolerant (Table 1). The cold tolerant lines were also resistant to ascochyta blight under field conditions. Besides morphologically different types, tall, erect and lateY maturing types were especially selected, since most of the lines that showed resistance to ascochyta blight had these traits (Singh and Reddy 1991). Similarly, Haq and Singh (1994) designed a mutationYbreeding program and successfully selected a cold tolerant and ascochyta blight resistant line, M 16119, for the first time. This mutant was also very lateYmaturing type. Our results have clearly suggested that mutation techniques can be effectively used in inducing complex traits that inherited quantitatively such as cold tolerance and ascochyta blight in chickpea.
