[ Objective] The study aimed to research the artificial hybridization between the durum wheat ( Triticum aestivum) with the local cultivated wheat ( T. durum) in Qinghai Province so as to provided the reference basis for improving the cultivated wheat varieties in Qinghai Province by using the hard wheat. [ Method] With the cultivated wheat in Qinghai Province as female parent and the hard wheat as the male parent, they were made for distant artificial hybridization and their seed-setting rate of hybridization and the germination rate and seedling rate of F1 generation were studied. [ Result ] The seed-setting rate of hybridization between the durum wheat and the cultivated wheat was 48.56％,the germination rate of F1 generation was 31.68％ and the seedling rate of F1 generation was 34.65％. [ Conclusion] There was some crossability between the durum wheat and the cultivated wheat and the seed-setting rate, germination rate and seedling rate of different cross eombinations showed a significant difference.%[目的]研究青海当地栽培小麦品种与硬粒小麦的人工杂交,为利用硬粒小麦来改良青海栽培小麦提供参考依据.[方法]以青海省栽培小麦为母本,硬粒小麦为父本进行远缘人工杂交,研究杂交结实率以及F1代的发芽率和成苗率.[结果]栽培小麦与硬粒小麦杂交结实率为48.56%,F1 代发芽率为31.68%,成苗率为34.65%.[结论]普通小麦与硬粒小麦具有一定的可杂交性,不同组合杂交结实率、发芽率和成苗率差异显著.
