A series of studies is proposed jointly between the University of Georgia and the Guangdong Rice Research Institute on determining how photosynthesis has been increased in a new hybrid rice developed in China. On-going experiments in China indicate that the utilization of photosynthetic heterosis in a hybrid rice, from a US high-light adapted ecotype crossed with a South China low-light adapted ecotype, is a promising approach to increasing photosynthesis, broadening environmental adaptability, and increasing productivity. In this project, coordinated studies will be conducted to compare a hybrid rice (Le/Qi) and its parents to determine how photosynthesis has been modified. Portions of the work will be conducted at three sites -- Georgia, Arkansas, and China.

佐治亚大学和广东水稻研究所联合提出了一系列研究，以确定中国开发的一种新型杂交水稻的光合作用是如何增加的。中国正在进行的试验表明，利用美国强光适应生态型与华南弱光适应生态型杂交水稻的光合优势，是增加光合作用、扩大环境适应性和提高生产力的一条有希望的途径。在这个项目中，将进行协调研究，比较杂交水稻（乐/齐）和它的亲本，以确定光合作用是如何被改变的。部分工作将在三个地点进行——佐治亚州、阿肯色州和中国。
