| Abstract: | The presence of genes for resistance to stripe rust ( Puccinia striiformis ) was studied in 39 wheat cultivars from Shaanxi, Gansu and Sichuan provinces based on determining their reactions to 16 alien and 4 Chinese strains with different virulent genes and analysing their pedigrees. Only 8 known genes Yr1,Yr2,Yr3,Yr7,Yr9,Yr10,YrSu and YrSD,either alone or in combination,were postulated in 20 of 39 wheat cultivars tested. Gene Yr9 derived form rye was present in 11 cultivars. The results also showed that 3 cultivars were resistant to all isolates and 2 resistant to most of the isolates tested,which implied the presence of unknown major Yr-gene(s). The remaining cultivars probabley had some addi-tional genes which were effective against only a few races. |
