摘    要:利用八倍体小偃麦与普通小麦杂交、回交,选择异附加系和异代换系小麦新种质,再利用这些新种质与普通小麦杂交,培育出了早熟型小麦新品种-早优504。该品种比对照小偃6号早熟5~7d;培育出优质高产型小麦新品种-小偃503。该品种蛋白质含量165g/kg,沉淀值46.4ml,稳定时间13.0min,比对照陕229增产3.9%;培育出高产,抗逆性强小麦新品种-小偃597。该品种抗旱,后期耐阴雨,成熟黄亮。

Abstract:Some new germplasm resources, alien addition lines and substitution lines, were created by crossing between octoploid Tritielytrigia types and Triticum aestivum. With the germplasm resources and common wheat crossing, various types of wheat varieties were developed. The early maturing type variety Zaoyou 504 is 5 to 7 days earlier than CK Xiaoyan No.6. The high yield and good quality variety Xiaoyan 503 is 3.9% increase over CK Shan229. It contains 165g/kg protein. The precipitation value is 46.4ml, and the stabilization time is 13.0 minutes. The high yield and resistance to adverse circumstance variety Xiaoyan 597 is noted for its resistance to drought and excessive rain in later period.
Keywords:Octoploid Tritielytrigia types   Triticum aestivum   Distant hybrid   Wheat varieties
