The discovery of a new kind of cytoplasmic male sterility accession in Brassica napus L.

摘要：

One male-sterile plant was discovered in rapeseed (BRASSICA NAPUS L.) in 2002. Compared with fertile plants, the male sterile plant was charactered by stamen like halberd, no pollen in anther, the long stamens of some flowers together, and normal pistil. The YZA CMS was gotten by backcrossing with rapeseed (B. NAPUS L.). Compared with Pol CMS and GMS, the YZA CMS stamens are higher, and the proportion of pistil vs. stamen higher too. The testcross offspring and backcross offspring with Pol CMS maintainer and restorer are all sterile. We thought that the YZA may be a new kind of cytoplasmic male sterile accession.
