Genetic correlation and path analysis of main photosynthetic characters and grain yield in corn



Genetic correlation and path analysis of main photosynthetic characters and grain yield in corn



Journal of Shandong Agricultural University 23(2): 149-153



In a field test during 1986, 9 characters related to photosynthesis and also grain yield were studied in 15 hybrids from a diallel cross involving 6 inbred lines of maize. Genetic correlation analysis revealed significant positive correlations between leaf area/plant, area of the three leaves near the ear and leaf area of seedlings at the grain filling stage. Leaf orientation value was significantly and negatively correlated with all leaf area characters and effective grain filling period.
