摘要
龙丰A是以(珍汕97B/博B)F1为母本,(博B/桂2)F1为父本杂交制保后,再与博A测交并连续回交转育而成的优质软米型不育系。该不育系农艺性状优良,花粉败育彻底,育性稳定,异交习性好,配合力强,米质优,于2013年6月通过广西农作物品种审定委员会田间技术鉴定。
Longfeng A, derived from the cross of Bo A/（Zhenshan 97B/Bo B F1//Bo B/Gui 2 F1）, is a new high-quality indica CMS line with soft-grain characteristics in cooking rice. The CMS line is characterized by good agronomic traits, complete pol en sterility, stale fertility, favorable outcrossing habits, high combining ability and good grain quality. It was technical y identified by Guangxi Crop Variety Appraisal Committee in June, 2013.
