Effect of Yellow Rust (Puccinia striiformis West) Causatives on Growth Dynamics, Morfological Features, Grain Quality and Yield of Bread Wheat Cultivars in Azerbaijan

Influence of yellow rust disease on bread whaet cultivars (Tricticum aestivum L.) was studied in Absheron and Tartar Regional Experimental Stations. Leaf surface assimilation area, dry mass and intensity of photosynthesis decreased depending upon the disease severity and the vegetation development phases. Simultaneously, grain quality parameters and yield of studied cultivars declined
