Abstract
F2 seedlings of monosomics I-XV of A. sativa cv. Manod x A. sativa cv . mostyn (S. 242) and 41-chromosome I-XV of A. sativa cv. Manod x A.sativa cv. Cc 7718 were investigated for segregation of resistance
to race 2 of mildew ( Erysiphe graminis s. sp. Avenae). There was no significant deviation from 3 resistant : 1 susceptible in a number of lines while a few lines showed significant deviation from 3 resistant: 1 susceptible but the deviation was due to higher number of susceptible plants. It seems that the gene controlling resistance to race 2 of mildew is not located atleast on any one of them monosomes so far available.
