配制了普通小麦与阿拉拉特小麦的正、反交组合２０个，杂交结实率为４．９％～３３．６％。不同组合杂种Ｆ１每个ＰＭＣ平均的单价体为１５．２０～１８．５５，二价体为７．０３～９．０２，三价体和四价体分别为０．３６～１．１５和０．０１～０．０２。通过对杂种后代连续２年成株期混合菌种抗性鉴定和苗期分小种分菌系鉴定表明，从普通小麦中国春与阿拉拉特小麦的杂种Ｆ３和Ｆ４代已选择到对白粉病高抗～免疫的单株，它们具有４２条染色体，在ＰＭＣ′ｓＭＩ形成０．００～０．４６个单价体，２０．７７～２１．００个二价体，０．００～０．０６个四价体，在细胞学上已稳定。与已知白粉病抗性基因比较的抗谱分析表明，阿拉拉特小麦携有主效抗病基因Ｐｍ２，在上述的杂交选择过程中，已通过遗传重组将Ｐｍ２基因导入到中国春中。
20 normal and anti-crossing combinations of common wheat and Aralate were prepared, and the seed setting rate was 4.9% -33.6%. The average unit price of PMC for each hybrid F1 was 15.20 ~ 18.55, the value of bivalents was 7.03 ~ 9.02, while that of triad and tetravalence was 0.36 ~ 1.15 and 0 .01 ~ 0.02. Through the identification of the hybrid strains of hybrid progeny for two consecutive years at seedling stage and the identification of the seed germinating strains, the F3 and F4 generations of F1 hybrids from Chinese Spring and Aralal wheat have been selected to powdery mildew Highly resistant to immunized individuals, which have 42 chromosomes, formed 0.00 to 0.46 monovalent, 20.77 to 21.00 bivalents in the PMC’sMI, 0.00 to 0.06 Quadrivalent, cytologically stable. Compared with known powdery mildew resistance genes, the anti-spectrum analysis showed that the Pratt & Whitney disease resistant gene Pm2 was introduced into the wheat and the Pm2 gene was introduced into the Chinese spring through genetic recombination during the above hybridization selection.
