Variation Law of Seed Oil Content and Yield of Xanthoceras sorbifolia Populations in Different Areas

AO Yan (Forestry Institute,Chinese Academy of Forestry Sciences,Beijing 100091)  
[Objective] The study aimed to compare and analyze the variation law of seed oil content and yield of Xanthoceras sorbifolia Bunge.in different distribution areas.[Method] With 6 populations of X.sorbifolia in main distribution areas as tested materials,the oil contents in seed,seed kernel and seed coat were measured by the nuclear magnetic resonance technology and the variation condition of seed oil content and yield between the population and within the population were analyzed.[Result] 4 traits were all significant different among 6 populations and there was no significant difference between the single plants within population.Differentiation on the oil content and yield between populations were higher than that within populations.The highest oil content of seed and seed kernel were in the population from Yuxian county(36.72%,67.20%) and that of seed coat was in the population from Chengde(12.50%).The highest yield was in the population from Shanxian County(1 166 g).The correlation of oil content and yield of X.sorbifolia to geography climate factors was not significant.According to cluster analysis,6 populations could be divided into 3 classes with low yield and high oil content,medium yield and medium oil content and high yield and low oil content,on base of which,the populations were could be selected according the beading need.[Conclusion] Genetic improvement of X.sorbifolia could be done by population selection.
