摘要
灵红A是以珍汕 97A为母本 ,用自选的灵优占为父本杂交并经多代回交转育而成的优质籼型新不育系。灵红A不育性稳定 ,柱头发达、外露率高 (92 % ) ,异交结实率高 ,易于繁殖制种 ,而且抗性较强 ,农艺性状较优良 ,可恢复性好 ,配合力高 ,杂种一代产量高、米质优。该不育系于 2 0 0 0年 7月通过广西区技术鉴定。
Linghong A, developed from the cross of Zhenshan 97A/Lingyouzhan and its backcross with Lingyouzhan as the recurrent parent, is a new indica CMS line with good grain quality in rice. It has the characteristics of complete and stable male sterility with 100% of male sterile plants and sterile pollens, good flowering habits with high stigma exsertion rate (as high as 92%) and high outcrossing rate as a result in easy multiplication and hybrid seed production, medium blast resistance, desirable agronomic characters, good restorability and high combining ability. Its F_1 hybrids show both high yield and good grain quality. It was certified technically in Guangxi in July, 2000.
