由广西大学著名水稻育种专家莫永生教授主持的“杂交水稻恢复系测253的选育与应用”通过广西壮族自治区科技厅组织的成果鉴定。20世纪80年代我国育出的优良杂交稻如汕优系列,一般产量比常规稻提高2成左右,但由于遗传基因不够多、系谱不够广等因素,随着种植年限的增加,一些品种的种性出现了退化,抗性、产量下降。由莫永生教授主持的这个研究项目就是要针对这些问题育成一系列不同类型、不同成熟
By the well-known rice breeding experts in Guangxi University Professor Mo Yongsheng chaired “hybrid rice restorement line 253 breeding and application ” through the Guangxi Zhuang Autonomous Region Science and Technology Department organized the results of appraisal. In the 1980s, excellent hybrid rice such as Shanyou series raised by our country showed a general increase of about 2% compared with that of conventional rice. However, due to insufficient genetic factors and insufficient pedigree, with the increase of planting years, some varieties Sexual degradation, resistance, decreased production. The research project led by Professor Mo Yongsheng is to cultivate a series of different types and different mature
