硬粒小麦具有小穗多花、耐旱等优异性状，为了评估将此性状导入普通小麦中的难易程度，对硬粒小麦与3份普通小麦进行正反杂交，统计杂交结实率以及F1发芽率和结实率。结果表明，反交的结实率较高（51.19％）；正交的发芽率较高（86.67％），而反交组合石家庄11号×周麦22发芽率为0。发芽率高低除了与细胞质有关外，也受普通小麦基因型差异的影响。

Durum w heat contains some useful traits such as multi-floret ,etc .In order to evaluate the degree of difficulty for transferring such excellent trait to common wheat ,the reciprocal cro-sses were made between one durum wheat and three common wheat genotypes .The seed setting rate of hybridization and the germination rate and setting rate of hybrids were studied .The result showed that the seed setting rate of hybridization was higher when durum wheat was used as fe-male parent (51 .19% in average) .The seed germination rate of hybrids was higher when durum wheat was used as male parent (86 .67% ) ,while the germination rate of the cross Shijiazhuang 11 × Zhoumai 22 was zero .In addition to the cytoplasm difference between common wheat and du-rum w heat ,the genotype diversity of common w heat played an important role in the germination rate of hybrids .
