普通小麦1031做为S^V型细胞质雄性不育系小麦保持系的鉴定

IDENTIFICATION OF A COMMON WHEAT 1031 TO BE THE MAINTAINER LINE OF S^V TYPE MAIE STERILE LINES

以1BS染色体上带有T.Spelta小麦R f3恢复基因的普通小麦1031与SV型细胞质雄性不育系杂交,通过杂交F1代的育性观察,结果表明普通小麦1031能保持SV型细胞质雄性不育系小麦的不育性,同时染色体C—分带显示普通小麦1031是属于非1B/1R型保持系.这是一个新发现,扩大了SV型细胞质雄性不育系小麦保持系极少的资源,为SV型细胞质雄性不育系小麦在北方春麦区利用,提供基础材料.

The common wheat line 1031 carrying Rf3 gene on T.Spelta wheat 1BS chromosome was crossed with the SV type male sterile line.In F1,studying its ferility,the result shows that 1031 can maintain sterile of SV type male sterile line.And studying chromosome C-balling shows that 1031 is a maintainer line of non 1B/1R type.This is a new diversity that increase resources of the less maintainer lines.It provides a basic material that SV type male sterile lines can be utilized for the spring wheat in North.
