提高普通小麦与碱草杂交结实性的研究

A Study on Incrcase in Setting Rate of Distant Cross between Wheat and Aneurolepididum chinens

利用小麦、小黑麦、小偃麦与赖草属碱草（Ａｎｅｕｒｏｌｅｐｉｄｉｄｕｍｃｈｉｎｅｎｓ）远缘杂交，观察当代结实率和杂种Ｆ１结实性。结果表明，利用ｐｈｌｂ、四倍体小麦、八倍体小偃麦与碱草杂交可以提高结实率和Ｆ１成活率。

This paper mainly introduces the results in setting rates of distant crosses between Triticum, Triticale, Trititrigia and Aneurolepididum chinens respectively and the corresponding F1 fecundity. Crosses between ph1b, Tr. turyidum, octoploid Trititrigia and A. chinens respectively have high F0 setting rates and survival rates.
