河北省主要小麦育成种矮源研究

Studies of Dwarf Sources on Major Wheat Varieties Bred in Hebei

利用赤霉酸敏感性测定和系谱追踪方法，对河北省历年来培育的主要冬小麦品种的矮秆基因进行了鉴定分析。结果表明：７０．８％的品种的矮秆基因来自农林１０号；２２．２％的品种的矮源为赤小麦；６．９％的品种的矮源为郑引１号。５２．４％的河北省定名品种的矮秆基因来自赤小麦。部分品种的矮源还不清楚。

Eighty-nine winter wheat varieties bred in Hebei were studied by response to gibberellic acid (GA3) and family analysis. The results showed that dwarfing genes of 70. 8% varieties derived from Norin 10 with Rht 1 and (or) Rht2, that dwarfing genes of 22. 2% varieties derived from Akagomugi with Rht 8 and (or) Rht 9 and that dwarfing genes of 6. 9% varlettes derived from St2422/464 with Rhtls. However, dwarfing genes of 52. 4% registering varlettes derived from Akagomugi. The dwarf sources of some varieties were not clear.
