Provenance trails including 21 provenances,introduced from Guangxi,Yunnan,Guangdong,Hunan,Jiangxi and Guizhou provinces,was used to study geographic variation pattern of seed character and seedling growth.Seed and seedling characters including seed length,seed width,100-grain weight et al were analyzed.The variance analysis result showed that differences between seed and seedling characters from 21 provenances all reached the significant or extremely significant level.The genetic variation coefficients of seed length,seed width,100-grain weight,seedling height were 22.43%,23.32%,75.33%,33.85% and the broad-sense heritability were 0.986,0.984,0.999 and 0.949.Seed and seedling characters had high heredity ability.Correlation analysis of result suggested that negative correlation was highly significant between One-hundred-grain Weight with rainfall.Between the quantity of leaves and annual average temperature,between the quantity of leaves and sunshine duration both showed significant negative correlation.Clustering analysis result showed that 8 provenances including Liping in Guizhou province,Zhaoping in Guangxi province,et al,were super,their average phenotype gains and genetic gains of seedling height were 37.41% and 35.50%.The volume output of the super prevenances was significant.
