Genetic Variations and Correlation analysis on the Main Quantitative Characters of the Peanut Germplasm Resources in Fujian

The genetic variation coefficients,broad heritabilities.genetic advances,correlation coefficients,correlative heritabilities and path coefficients of main quantitative characters of the selective peanut germplasm resources in Fujian were studied.The results showed that genetic variation coefficients were larger in most characters and different among the characters.The heritabilities were also different with various characters and the genetic advances of most characters were large,indicating that significative effect should be obtained to select on these characters with a larger gentle advance.There were positive correlations among characters studied with the pod yield per plant and the pod yield per plot.Path analysis indicated that direct path coerricient was more signifocant in the 100-pod weight to the pod yield per plant positively.Direct path coerricient was also signigicant in the mature pod per plant to the pod yield per plant and showed positive value.However,direct effect was minor in the number of fruit branches to the pod yield per plant.The performence of peanut single plants in phenotype under Fujian ecological conditions also be discussed.
