摘要
绵 2A是以绵 2B(香改B Ⅱ 32 8B∥K19B)为父本、珍汕 97A为母本测交和连续回交选育而成的野败型优质不育系。该不育系不育性稳定 ,花粉败育彻底 ,不育株率和花粉不育度均为 10 0 % ,农艺性状优良 ,遗传性状稳定 ,米质优 ,柱头外露率高 ,易于繁殖、制种 ,配合力好 ,杂种一代优势强、米质优。 2 0 0 1年 8月通过四川省技术鉴定。
Mian 2 A is a new WA type CMS line developed through crossing Mian 2B (Xianggai B/Ⅱ 32 8B∥K19B) to Zhenshan 97A and successively backcrossing with Mian 2B as recurrent parent. It was technically certified in Sichuan in August, 2001. It shows a complete and stable male sterility with 100% sterile plants and pollens. It has the characteristics of good plant type, fine grain quality, desirable agronomic characters, high outcrossing rate and good combining ability. Its F 1 hybrids show both high yield potential and good grain quality.
