Abstract:

Huapei No. 5 was a new wheat variety developed through crossing Yu No.18 with Hua No. 4-3 by Crop New Variety Key Laboratory of He'nan Academy of Agricultural Sciences. It was released by anther culture and certified by national crop variety releasing committee in 2006. The breeding characteristics of Huapei No. 5 were as follows: two parents complement well; its genetic background was rich; the combination presented a high inducing rate that provided a large amount of separate population; the progenies population characters were used as main selection target which enhance the selective accuracy；its yield comparative test was carried out at two different areas, which shortened the breeding period. Through Huanghui regional test, production test and extention and planting practice, Huapei No. 5 is proven to be an excellent winter wheat variety with properties of high and stable yield, good quality, and extensive adaptability. It is suitable to grow as a mid-late seeding variety in mid-high yield and water-fertilizer field in southern Huanghui winter wheat region.
