| Abstract: | Zhan A is a new cytoplasm indica CMS line released by Guangdong Ocean U niversity, which derived from crossing and backcrossing of the Dongguan wild rice (CMS gene donor) with the selected hybrids of "MeiqingB×Ⅱ-32B"( nuclei gene donor). It has been technically tested and appraised by Guangdong Province for its stable sterility-characteristics of 100% of sterile plants, 99.95% of pollen sterility and 95.64% of typical abortive. It also has characteristics of high out put in crossing settting, wide spectrum of restorability, good combining ability, and strong resistance to rice blast, modenrate resistance to bacterial blight. Two of its elite combinations in hybrid rice, Zhanyou1018 (Zhan A/HR1018) and Zhanyou226 (ZhanA/HR226), were registered and appraised by Crop Variety Test Committee of Hainan and Guangdong in 2003 and 2006 respectively. |
