摘  要:
永3A是以高产早熟的早稻品种中98-15为母本与优质早稻品种赛晚早籼1号杂交后,F4选单株再与金优207A测交并回交转育而成的三系不育系。该不育系不育性稳定,开花和异交习性较好,配合力高,可恢性好,直链淀粉含量较低(12.2%),具有早熟显性效应,容易配出早晚兼用的早熟、高产、优质组合。永3A及其所配组合永3优华占均于2016年5月通过江西省农作物品种审定委员会审定。

摘  要:
Yong 3A is a new CMS line in rice developed by successive backcrossing between Jinyou 207 A and the F4 plants selected from the cross of Zhong 98-15( an early-maturing high-yielding early rice variety) and Saiwanzhaoxian 1( a fine-quality early rice variety). It is characteristic of stable complete male sterility,good flowering and outcrossing habits,good restorability and low amylose content( 12. 2%). Besides,it has the dominant effect of early maturity,so such hybrids with early maturity,high yield and fine grain quality to be used for both early cropping rice and late cropping rice could be easily developed from it. In May,2016,Yong 3A and its hybrid Yong3 You Huazhan( Yong 3A/Huazhan) were both registered and released by Jiangxi Provincial Crop Variety Appraisal Committee.
