Appropriate pathotypes of stem rust and leaf rust for evaluating resistance in durum wheat and bread wheat

摘要

Differential response of durum and bread wheats to selected cultures of leaf rust has been reported from India (Pandey and Rao 1984; Sharma et al. 1996). Hence, a study was conducted to assess the suitability of different leaf rust pathotypes for evaluating resistance in durum and bread wheats, and to find out whether the two wheat species respond differently to various cultures of stem rust also. The present communication reports identification of appropriate pathotypes of leaf rust and stem rust for evaluating resistance in durum and bread wheats, based on the above study involving seedling tests of a number of host genotypes with different rust cultures.
