摘要
Wheat-barley addition lines 7H, 2H, 3H, 4H, 6H and 5H having barley chromosomes 1, 2, 3, 4, 6 and 7, respectively, were evaluated for resistance to karnal bunt (Neovossia indica) using syringe inoculation of sporidial suspensions of N. indica under glass-house conditions. Addition lines 4H and 7H were rated as highly resistant and resistant, respectively, with zero and 3.22 coefficients of infection compared to 'Chinese Spring' which had a 23.5 coefficient of infection. All the six addition lines were found to be susceptible to specific virulences of Puccinia recondita tritici and P. striiformis.
