Karnal Bunt Resistance in Wheat‐Barley Addition Lines

摘要

AbstractWheat‐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 ofN. indicaunder glasshouse 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 ofPuccinia recondita triticiandP. striif
