Abstract
The stripe rust resistance of 48 wheat productive varieties,preserved varieties and lines was studied by field survey and molecular marker for resistance gene under natural infection of stripe rust in fields to know stripe rust performance of wheat varieties and screen disease resistant varieties in Tibet.19varieties(lines),24varieties(lines)and 5varieties(lines)are of resistance to stripe rust,non-resistance to stripe rust and unstable resistance to stripe rust after two-year test respectively.The molecular detection results showed that 8varieties(lines)and 15varieties(lines)are of Yr15 positive sign and Yr26 positive sign separately but Yr10 positive sign is not detected in 48 tested varieties(lines).The results from field identification and molecular detection showed that 3varieties(lines)and 2varieties(lines)may carry Yr15 and Yr26 respectively and the occurrence frequency of Yr15 and Yr26 is 10.42%.In conclusion,introduction,breeding and extension of wheat varieties with good resistance to stripe rust should be further strengthened because the resistance to stripe rust of wheat varieties(lines)is poor and the resistance genes with strong resistance to stripe rust is relatively less in Tibet.
