摘要

摘要Desmanthus属具有广泛的生态地理分布和复杂的分类学特征。伯南布坎努斯（Desmanthus pernambucanus（L.）Thellung，在巴西俗称Juremiha，是一种原产于巴西东北部地区的豆科物种，以其高蛋白质含量、耐旱性和对动物无毒性而闻名。这项工作的目的是通过种质交换富集巴西东南部Nossa Senhora das Dores的Embrapa Tabuleiros Costeiros的Desmanthus基因库，评估来自英联邦科学与工业研究组织（CSIRO；澳大利亚）的15个后代的遗传多样性。使用了15个ISSR标记，从中选出8个。被鉴定为242、245、246、255和268的后代是遗传距离最远的，也是最推荐引入基因库的。

Exchange of germoplasm and genetic diversity to enrichment the Desmanthus genebank

ABSTRACT The genus Desmanthus presents wide ecogeographical distribution and complex taxonomy. Desmanthus pernambucanus (L.) Thellung, popularly known in Brazil as Jureminha, is a leguminous species native to the Northeast region of Brazil, which stands out by its high protein content, resistance to droughts, and by presenting no toxicity to animals. The objective of this work was to evaluate the genetic diversity of 15 progenies from the Commonwealth Scientific and Industrial Research Organization (CSIRO; Australia), through germplasm exchange for enrichment of the Desmanthus genebank of Embrapa Tabuleiros Costeiros, in Nossa Senhora das Dores, SE, Brazil. Fifteen ISSR markers were used, from which 8 were selected. The progenies identified as 242, 245, 246, 255, and 268 were the most genetically distant, and the most recommended to be introduced to the genebank.
