Abstract —The seed bank of the Vavilov All-Russia Institute of Plant Genetic Resources (VIR) contains a wide range of landraces that were collected almost 100 years ago, in which natural selection might leave signatures through crop diversification. In this study, we analyzed 407 landraces sampled at centers of the origin of the chickpea and at sites of secondary diversity. We hypothesize that a fraction of single nucleotide polymorphisms might have exhibited strong selection to a range of environmental conditions that chickpea experienced during domestication and subsequent geographic distribution. Using the BayPass package we identified 13 polymorphisms; these assort by environmental conditions and are strong candidates for local adaptation.

鹰嘴豆地方品种基因组的生态适应特征

摘要——瓦维洛夫全俄植物遗传资源研究所 (VIR) 的种子库包含近 100 年前收集的各种地方品种，其中自然选择可能会通过作物多样化留下特征。在这项研究中，我们分析了在鹰嘴豆起源中心和次生多样性地点采样的 407 种地方品种。我们假设，一部分单核苷酸多态性可能对鹰嘴豆在驯化和随后的地理分布过程中经历的一系列环境条件表现出强烈的选择。使用 BayPass 包，我们确定了 13 个多态性；这些按环境条件分类，是当地适应的有力候选者。
