| 摘 要： | 荣丰A是广东省农科院水稻研究所用优ⅠB/博B的F4代优良株系与优ⅠA测交并连续回交转育而成的早熟抗稻瘟病籼型不育系,2005年10月通过广东省技术鉴定。荣丰A表现株型紧凑,不育性稳定,配合力强,抗稻瘟病,柱头外露率高,异交结实率高,对“九二○”敏感,易于繁制种。利用该不育系初步测配出杂交早稻荣优2号、荣优3号和荣优4号,在区试和试种中均比对照增产。

| Abstract: | Rongfeng A,developed by crossing the selected F_4 lines of You I B/Bo B to You I A with the successive backcrossing method,is an early-maturing indica CMS line.It was technically certified in Guangdong Province in October,2005.It is characteristic of good plant type,stable and complete male sterility,good combining ability,good blast resistance,high stigma exsertion rate,high out-crossing rate,good sensitivity to GA_3 and easiness for hybrid seed production.The early-maturing hybrid combinations Rongyou 2,Rongyou 3,Rongyou 4,derived from Rongfeng A,had a good performance in early maturity,high-yielding ability and disease resistance.In the regional trials and experimental productions,these combinations yielded higher than the check hybrids. |
