Phytopathological assessment of Azerbaijan origin bread wheat (Triticum aestivum L.) genotypes against yellow rust

Yellow rust (Puccinia striiformis f. sp. tritici) on bread wheat (Triticum aestivum L.) has resulted in significant reductions the yield losses and grain quality. Infection rate to yellow disease evaluation of SPAD value 90 soft genotypes we studied been implemented conditions Absheron Peninsula, territory Experimental Base ANAS ( N. 40°24.001? , E. 49°49.001? H. = 50 m. ) 2017-2020 years. was 0-100 S. An indicator changed from 28.9 83.5 between genotypes. The average this symptom 50.5. sample with highest genotype k9530 belonging Erythrospermum variety, which had an 83.5. 0 showed immune reaction. Different as can be seen appreciation resistance for different infection rates values. As a result evaluation, although there partial conformity, full sameness not observed. Some high values rust. cluster analysis is based Euclidean distance index WARD method PAST statistical software package. have grouped into 6 main clusters according indicated tokens. According euclidean index, farthest were variety k7252 Milturum (54.63). It explained by fact that they belong variety.
