以6个籼型杂交稻三系不育系和5个恢复系按不完全双列杂交设计配制的30个杂交稻组合及其亲本品种为材料,对其光合性状进行了测定和分析,结果表明:(1)杂交稻组合的光合特性存在显著或极显著的组合间遗传差异,光合特性的遗传变异主要来自基因的非加性效应;(2)胞间CO_2浓度、蒸腾速率、叶绿素a、叶绿素b和类胡萝卜素含量受不育系的影响大于恢复系,而气孔导度、叶绿素a + b含量受恢复系的影响大于不育系;(3)杂交稻光合性状的广义遗传力均大于狭义遗传力,各性状主要受基因互作及环境的影响。狭义遗传力的大小依次为叶绿素b、叶绿素a + b、叶绿素a、气孔导度、胞间CO_2浓度、类胡萝卜素和蒸腾速率,这些...

To verify the combining ability of photosynthetic characteristics of function leaves,thirty hybrid combinations were obtained from incomplete diallel cross between six sterile lines and five restorer lines of indica hybrid rice cultivars. The photosynthetic characteristics in hybrid combinations and their parents were measured and statistically analyzed. The results showed that there were significant genetic differences among hybrid rice combinations in photosynthetic characteristics. The genetic variations of photosynthetic characteristics mai...
