ABSTRACT

Brown and yellow rust development in variety mixtures was represented more precisely by coefficient of disease level (CDL), which incorporated infection type, rust severity and rust incidence into one value. The development of rusts declined in variety mixtures in comparison to their pure susceptible components. Mixtures of HD 2329 + WH 542 + UP 2338; RR 21 + PBW 226 + HUW 234; PBW 154 + Sangam + UP 2338 resulted decrease in brown rust by 51.85, 47.89 and 40.00 per cent; and in yellow rust by 50.00, 15.00 and 37.50 per cent, respectively over mean of their components. Variety mixtures yielded more than the total average yields of their components and exhibited lower yield reduction in absence of fungicide protection.
