摘要: Although Jatropha curcas L. is known as a source of oil-rich seeds economically viable substitute diesel, little currently about the genetic resource J. in China. In this study, RAPD and ISSR data were utilized to determine relationships among clones from Panzhihua, Five twelve primers generated reproducible amplification banding pattern 43 polymorphic bands out 126 scored accounting, for 34% polymorphism across clones. The UPGMA cluster analysis indicated two broad groups, one comprising all except YuanMou, which formed smaller second group. Congruously, samples belonging same origin grouped into their distinct lineages. overall grouping clustering was irrelevant oil content these This study provides valid guidelines collection, conservation characterization resources Panzhihua also further breeding program towards biodiesel production.
