A university research team from central China has successfully identified an important genetic code for enhancing rice grain yield by 7 to 15 percent.
The team, from Huazhong Agricultural University, has proven that a genetic marker in rice GY3 may boost grain yield by more than 20 percent if manipulated by the two-step pathway, and the introgression of CG3 can increase grain yield per plot by 7.4 percent to 16.3 percent in all investigated rice.
Their findings were published by Nature Genetics on Thursday.
Figure demonstration of the research.
Chinese people, who consumes the most amount of rice on earth, have been striving to find ways to increase rice production. The cultivation of high-yield and high-quality rice varieties is not only an important topic in the field of scientific research, but also related to food security.
China primarily grows the slender and long indica rice and the rounder ones, japonica rice. They've displayed differences in appearance characteristics and genetic formation after long-term breeding selection.
After 12 years of research and analysis, the team found that most indica rice breeds do not carry locus GY3 and the improved species with GY3 reintroduced have demonstrated 9.1 to 16.3 percent increase in yield.
"This also shows that GY3 has not been utilized for breeding," said Xing Yongzhong, the writer of the article.
