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.
