摘要:
光合速率的提高对大豆产量改良具有重要作用。本研究利用波高和南农94-156杂交所构建的RIL群体对4个光合性状QTL进行了初步定位。结果表明，大豆籽粒与光合速率间存在微弱的正相关，而4个光合性状间除光合速率与胞间CO2浓度外均为极显著的正相关。分别检测到1、2、1和2个QTL位点与光合速率（O连锁群）、气孔导度（A1和D1b+W连锁群）、胞间CO2浓度（G连锁群）和蒸腾速率（H和M连锁群）有关，相互间均不共位，前3个QTL解释的表型变异略低于10%，而后3个QTL可解释表型变异的10% 以上。
Abstract:
The increase of photosynthesis rate is important to improve yield in crop plants such as soybean. In the present investigation， a set of RIL population derived from the cross of Bogao and Nannong 94-156 was used to identify QTLs associated with photosynthetic traits including photosynthetic rate， stomatal conductance， intercellular CO2 concentration and transpiration rate， and correlation among seed yield and photosynthetic traits were also conducted. The primary results indicated that one， two， one and two QTLs were detected to be associated with photosynthetic traits including photosynthetic rate， stomatal conductance， intercellular CO2 concentration and transpiration rate and mapped to LG-O， A1 and D1b+W， G， H and M， respectively. Each QTL explained 8.0%~21.5% of phenotypic variation. No QTLs co-located each other. Correlation analysis showed there was lower relationship between seed yield and photosynthetic rate， significant and positive correlations were observed among four photosynthetic traits except that of between photosynthetic rate and intercellular CO2 concentration.
