中国研究人员在《自然?遗传学》杂志上发表报告说,他们找到了一个可同时提高水稻产量和品质的基因,未来可将其应用到超级杂交水稻新品种培育中。中国水稻育种的主要目的是保证产量提升,而高产水稻品质有时较差,如何解决“高产不优质,优质不高产”问题一直是水稻育种面临的难题。中国科学院遗传与发育生物学研究所傅向东研究 Chinese researchers report in the journal Nature Genetics that they have found a gene that can increase both rice yield and quality, which could be applied to the cultivation of new hybrid rice varieties in the future. The main purpose of rice breeding in China is to ensure the yield increase, while the quality of high yielding rice is sometimes poor. How to solve the problem that “high yield is not good, high quality is not high yield” has always been a challenge for rice breeding.
