摘要
D0 69是用中粳广亲和系 0 2 42 8作母本 ,用籼稻恢复系与多个籼稻中间材料的复交后代为父本 ,经杂交选育而成的广亲和恢复系。该恢复系株型好 ,分蘖力强 ,花粉量足 ,与Ⅱ -3 2A等不育系配组 ,有明显的杂种优势。其中 ,杂交组合Ⅱ优D0 69已分别于 2 0 0 1,2 0 0 2年通过重庆市和四川省农作物品种审定 ;冈优D0 69已于 2 0 0 1年通过四川省农作物品种审定。
D069 is a newly-developed wide compatibility restorer (WCR) line in rice, derived from the multiple cross of the wide compatibility medium japonica rice line 02428 (as maternal parent), indica restorer line (IR26) and other indica breeding materials. It has a good plant type, a strong tillering ability and a heavy pollen load. The F_1 hybrids from D069 and such CMS lines as Ⅱ-32A have an obvious heterosis. The combination Ⅱ You D069 (Ⅱ-32A/D069) was registered in Chongqing Municipality and Sichuan Province in 2001 and 2002, respectively. Another combination (Gangyou) D069 (Gang 46A/D069) was registered in Sichuan Province in 2001.
