摘要
９５Ａ是用９５占为父本、珍汕９７Ａ为母本杂交，再连续回交选育成的野败型不育系，不育性稳定，株叶型和粒型好，分蘖力强，有效穗多，穗长粒多，米质好，抗性好，柱头外露率高，异交结实率高，易于繁殖、制种。１９９６年７月通过技术鉴定。
A is a new WA-type CMS line developed through crossing 95 Zhan to Zhenshan 97A and successively backcrossing with 95 Zhan as the recurrent parent. It was technically certified in Guangxi in July, 1996. It shows a complete and stable male sterility. Its grain quality is fine to meet the second class standards of fine quality rice issued by the Chinese Ministry of Agriculture. It has good agronomic characters such as good plant type, strong tillering ability, many productive panicles and large panicle. Its flowering characteristics are also good with early and concentrated anthesis time and high stigma exsertion rate, resulting in a high yield in its multiplication and hybrid seed production. The techniques for its multiplication and hybrid seed production were also discussed in this paper.
