摘要： 65个山东地方普通小麦品种与奥地利黑麦进行杂交，结果表明，高亲和材料在山东麦区普遍存在。其中结实率大于50%的有10个品种，并有长芒透龙白，蚂蚱头火麦、小芒麦和白秃头4个品种的亲和性与中国春小麦相似，经t检验无显着差异，其基因型可能为kr1kr1kr2kr2；结实率在30%~50%间的品种有6个（其基因型可能为kr1kr1Kr2Kr2）；结实率在10%~30%间的品种有6个（其基因型可能为Kr1Kr1kr2kr2）;结实率在5%~10%间的品种有9个（其基因型尚难推测）;结实率小于5%的品种34个（其基因型可能为Kr1Kr1Kr2Kr2）；亲和性地理分布说明，供试材料中高亲和的品种在山东中部和南部有较高的出现频率。

Abstract: 65 land wheat races were crossed with rye to detect the difference of crossability among wheat genotypes of Shandong.The results showed that 31 land races from Shandong were crossable with rye.There were 10 land races with a seed-setting ratio of more than 50%, 4 of which were similar to the Chinese spring, their genotype might be kr1kr1kr2kr2; 6 land races with seed-setting ratio 30-50% (kr1kr1Kr2Kr2); 6 landraces with seed-setting ratio of 10-30% (Kr1Kr1kr2kr2); 34 landraces with a seed-setting of less than 5% (Kr1Kr1Kr2Kr2); and the other 9 landraces with the seed-setting ratio of 5-10%, their genotype was unknown.The genotypic distribution of the crossability showed that there were higher frequencies of high crossable land races in the southern and the middle regions of Shandong province.
