Abstract: In order to evaluate the genetic diversity and wheat stripe rust resistance for the regional trial wheat cultivars in Henan from 2008 to 2011,the pedigree information of 91 regional cultivars was investigated and the coefficient of parentage (COP) value between the parents and cross combinations was calculated.The cluster analysis was conducted based on the COP value.91 regional cultivars were inoculated with mixed races of Puccinia striiformis. There were 4 095 combinations.The range of COP value was 0.000 0-1.000 0 with the average value of 4.659 0; cluster analysis suggested that 91 cultivars could be divided into 10 groups.61.54% cultivars had stripe rust resistance.The genetic similarity and the stripe rust resistance increased year by year from 2008-2011.Zhoumai 13 and Zhoumai 16 which had the high stripe rust resistance were used widely maybe the main cause.
