摘要
笔者应用自己设计的聚合模型,把广亲和基因和野败型不育性恢复基因聚合为一体,从而育成了对三系法和两系法、品种间和亚种间杂种优势利用都可通用的恢复系.粳型通用恢复系适用于籼粳亚种间和粳粳品种间杂种优势的利用;籼型通用恢复系适用于粳籼亚种间和籼籼品种间杂种优势的利用.通用恢复系扩大了对不育系的应用范围,可以积极而又稳妥地实现袁隆平先生关于杂交水稻发展的总思路,即:三系法→两系法→一系法;品种间→亚种间→远缘杂交水稻过渡.
Rice general restorer is very important in the utilization of subspecific heterosis between indica and japonica. A special accumulative model (SAM) designed by ourselves was conducted to develop general restorer in hybrid rice breeding program. In terms of SAM, we have developed the general restorer Possessing restoration and compatibility which can apply to indica/indica or japonica/japonica, indica/japonica or japonica/indica: two-line method or three-line method hybrid rice. Japo-nica general restorer is suitable to indica/japonica or japonica/japonica and indica general restorer applicable to japonica/indica or indica/indica hybrid rice. The range of utilizing male sterile line is expanded with the general restorers. It is verv useful to the improvement of three-line method and the transit of three-line method to two-line method; and also helpful to the promotion of varietal hybridrice and the transit of varietal hybrid rice to subspecific hybrid rice so that actively and reliably realize the developing strategy suggested by professor Yuan Longping from three-line method to two-line method, and then one-line method; from varietal hybrid rice to subspecific hybrid rice, and then distant hybrid rice.
