20年来,我们在利用有性杂交培育高粱新三系的同时,结合育种工作进行了性状、亲缘和育性三者同时组配规律的研究。先后育成忻粱7号、忻粱52号、忻粱80号和忻粱202号恢复系及02A 不育系等新三系,均具有性状优良、杂交优势大、育性好的特点。这些恢复系国内已广泛应用。其杂交种(晋杂6号、晋杂7号、晋杂9号以及原杂10号等)全国已推广900余万亩。现根据试验资料初步分析如下。
In the past 20 years, we used the sexual cross to cultivate the new three lines of sorghum. At the same time, we carried out the research on the simultaneous rules of characters, relatives and fertility combined with the breeding work. Successively bred Xinxin 7, Xin Liang 52, Xin Liang 80 and Xin Liang 202 restorer lines and 02A CMS and other new three lines, all with good traits, hybrid advantages, good fertility. These recovery system has been widely used in China. The hybrids (Jin miscellaneous 6, Jin miscellaneous 7, Jin miscellaneous 9 and the original miscellaneous 10, etc.) the country has promoted more than 900 acres. Preliminary analysis based on experimental data are as follows.
