摘要
以 IR2 6为主体轮回品种 ,采用聚合回交法育成的丽恢 6 2 16等一批恢复系 ,不仅抗稻瘟病能力强 ,而且配合力强。用新恢复系所选配的 优 6 2 16等组合 ,在各级区试中产量表现突出 ,并且抗稻瘟病。
A serious of rice new restorer lines,such as “Lishui 6216”,were bred out by convergent backcross,their main recurrent parents were IR26 restorer lines Their resistant ability to blast and combining ability were obviously improved according to their performance Some of new hybrid rice combinations,such as “Ⅱ you 6216”,which were crossed and selected by the new restorer lines showed their well yielding performance,resistance to blast and good grain quality in different regional trials
