The correlation and path analysis on the quantitary characters of Chinese pine

Data of parental phenotype characters were obtained from 12 natural populations of Chinese pine (Pinus tobulaeformis Carr.) of four regions in Shaanxi province. The relationships of the phenotype characters of Chinese pine were studied with correlation and full-path analysis in parental and offspring phenotype characters. In the mean time, the relationships of environment, enzymes parameter and phenotype characters were studied through corrcation analysis.
