小麦优良亲本材料1B/1R易位系的研究

Selection of Elite Parent Material Carrying 1B/1R Translocation and Its Application in Wheat

通过近２０年的聚合杂交，将来自高加索（Ｋａｖｋａｚ）和美国的ＷｅｉｑｕｅＲｅｄ－ｍａｃｅ两个１Ｂ／１Ｒ易位的优良基因，以及墨西哥矮秆基因，渗入到我省自育的优良小麦品种中，育成了１Ｂ／１Ｒ易位系“绵阳８１６８—０—１４”。经多年观察、鉴定和配合力测定，该材料表现出产量结构合理、综合抗病力强、亲本的配合力好、杂种Ｆ１代优势明显等突出优点，是实现我省小麦高产育种可资利用的创新材料。

Through twenty years convergent cross, Mianyang 8168-0-14,a translocation line carrying 1B/1R translocation,was developed, which combined the dwarf gene from Mexico and the elite genes of both wheat varieties, Kavkaz from USSR and Weique Redmace from USA containing 1B/1R Translocation. This material had reasonable yield component, highly comprehensive resistance to diseases, high combining ability and obvious hybrid vigor.It was the innovatory material that can be used in the high yield breeding of wheat in Sichuan.
