中文摘要	Jatropha curcas (jatropha) is a potential biodiesel crop. A major limitation in production is that jatropha remains wild with low genetic variation. Related species/genera in the Euphorbiaceae can potentially be used for its genetic improvement. In this study, we employed inter-simple sequence repeats (ISSRs) to assess genetic variation among 30 accessions of jatropha, two accessions of bellyache bush (Jatropha gossypifolia), two accessions of spicy jatropha (Jatropha integerrima), two accessions of bottleplant shrub (Jatropha podagrica), and three accessions of castor bean hybrids. Genetic relationships were evaluated using 27 of 86 ISSR markers, yielding 307 polymorphic bands with polymorphism contents ranging from 0.76 to 0.95 for IMPN 1 and UBC 807 markers, respectively. Dice's genetic similarity coefficient ranged from 0.39 to 0.99, which clearly separated the plant samples into seven groups at the coefficient of 0.48. The first group comprised J. curcas from Mexico, the second group comprised J. curcas from China and Vietnam, the third group comprised J. curcas from Thailand, the fourth group was J. integerrima, the fifth group was J. gossypifolia, the sixth group was J. podagrica, and the last and most distinct group was Ricinus communis. Analysis of molecular variance revealed that 63% of the variability was attributable to variation among groups, while 37% was due to variation within groups. Based on Nei's genetic distance, the population from G2 (J. curcas from China) and G4 (J. curcas from Vietnam) had the least ISSR variability (0.0668), whereas G8 (R. communis) and Jatropha spp. displayed the highest distance (0.6005-0.7211).
