Study on Characters of F_1 Hybrids Derived from Distant Cross between Triticum aestivum and T.durum

[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 combinations showed a significant difference.
