摘要
回顾了广西杂交水稻区试历程,通过对2006、2007年广西杂交稻区试结果进行具体分析,肯定成绩,发现问题,并提出对今后发展方向的建议。2年来的区试结果表明,广西杂交水稻区试的参试组合类型配套齐全丰富,在选育组合数量,产量水平及稻米品质方面取得较大进步。但是存在着一些影响育种突破的重要问题。首先,参试组合很难在抗病虫上有所突破。其次,参试组合的综合性状有待进一步提高。今后,杂交水稻育种应扩大遗传基础,加大籼粳稻种质的遗传利用,加强野生稻优异种质的利用,把抗性育种放到主要议事日程,进一步促进杂交水稻综合性状的改良与协调,向超高产稻方向发展。
The process of Guangxi hybrid rice trail conducted in 2006 and 2007 had been reviewed and through the analyzed data,some suggestions for further improvement of Guangxi hybrid rice trail were pointed out by the authors. The two years data of the trail shown that abundance of hybrid combinations were tested and more progresses on quantity, yield and quality of hybrid rice were obtained, but there are still some problems such as resistance to insect and disease , and the integrated traits, which affecting the breakthrough of hybrid rice breeding. So the authors suggested that the genetic bases of new hybrids should be expanded, through strengthening genetic utilization between indica rice and japonica rice, utilization of elite wild rice germplasm and to put resistance breeding of hybrid rice into important position of daily work. And make further improvement on integrated traits and their coordination forward to breeding super high yielding rice hybrids in the future.
