中文摘要：万金A是广东海洋大学农业生物技术研究所以印尼水田谷型不育系优IA为母本,用博B∥金23B澳/洲袋鼠占后代中优良单株为父本杂交,并连续回交转育而成的具有互作型弱感光特性的籼稻不育系。该不育系育性稳定,不育株率100%,花粉不育度99.99%,开花习性好,异交率较高,米质达国标优质稻谷3级标准,配合力强,所配杂交稻组合具有弱感光特性,丰产性好。万金A于2005年9月通过广东省科技厅组织的技术鉴定,配制的高产优质组合万金优133于2006年5月通过了广东省品种审定。

外文摘要：Wanjin A, derived from crossing Indonesian Paddy type CMS line You I A with the selected plants from Bo B∥Jin 23B/Australian Kangaroo Zhan and backcrossing successively, is an indica CMS line with the characteristic of weak sensitivity to photoperiod induced by gene interaction. It shows the characteristics of stable sterility with 100% of sterile plants and 99.97% of pollen sterility, good flowering habits and higher out-crossing rate for easy and high-yielding multiplication and hybrid seed production, high combining ability, good grain quality （meeting the state standards of fine quality rice）. Most of its F1 hybrids have weak sensitivity to photoperiod. It was technically certified in Guangdong Province in September, 2005. Wanjinyou 133 （Wanjin A × HR133） , one of its elite F1 hybrids with high-yielding ability and good grain quality, was registered and released for commercial production in Guangdong Province in May, 2006.
