Determining the impact of stripe rust and leaf rust on grain yield and yield components' losses in Indian wheat cultivars

Abstract

Rust diseases continue to cause economic losses to wheat production worldwide. Host-plant resistance significantly non-racespecific or combining race-specific and non-race-specific resistance is the most efficient, economic and ecofriendly way to control wheat rusts, besides eliminating the use of fungicides. Evidence on the effects of race-specific and non-race-specific resistance categories on stripe rust caused by Puccinia striiformis Westend. f. sp. tritici Eriks. and Henn and leaf rust (Puccinia triticina) development and in defending yield component losses in Indian wheat cultivars is still limited. Experiment was conducted to study the impacts of stripe rust and leaf rust on grain yield and yield components of some Indian wheat cultivars under artificial epiphytotic conditions. Cultivars with highly effective adult plant resistance to stripe rust viz.
