对５个自交系及其组配的４个杂交种光合性能的分析表明，杂交种较其亲本在光合面积上表现出三种关系类型，即居中、偏高亲、超高亲；而在光合时间上表现为负优势；在光合速率上表现为正优势，幅度在３．１％～２３．４％，超高亲２．４％～９．３％。光合速率杂种优势与叶绿素含量有关。杂交种的叶绿素ａ／ｂ和类胡萝卜素／叶绿素较亲本有降低的趋势。结合产量及有关性状分析表明，杂交种较自交系不仅在源上而且在库系统上均有明显改善
The analysis of photosynthetic properties of 4 inbred lines and their 4 hybrids showed that the hybrids showed three types of relationships in their photosynthetic area, Photosynthetic time showed negative advantages; photosynthetic rate showed a positive edge, the range of 3.1% ~ 23.4%, super-parents of 2.4% to 9.3%. Photosynthetic rate heterosis and chlorophyll content. The hybrid chlorophyll a / b and carotenoid / chlorophyll than the parent trend. The analysis of yield and related traits showed that hybrids had significantly improved both in source and in library systems as compared with inbred lines
