  abstract = {{P}remise of the study: {C}rop wild relatives represent important genetic resources for crop improvement and the preservation of native biodiversity. {E}ggplant ({S}olanum melongena), known as brinjal in {I}ndia, ranks high among crops whose wild gene pools are underrepresented in ex situ collections and warrant urgent conservation. {K}nowledge of outcrossing rates and patterns of genetic variation among wild populations can aid in designing strategies for both in situ and ex situ preservation. {M}ethods: {W}e used 14 microsatellite (simple sequence repeat) markers to examine genetic diversity, population structure, and outcrossing in 10 natural populations of wild/weedy eggplant ({S}. insanum = {S}. melongena var. insanum) and three cultivated populations in southern {I}ndia. {K}ey results: {M}ultilocus {F}-{ST} analyses revealed strong differentiation among populations and significant isolation by distance. {B}ayesian model-based clustering, principal coordinate analysis, and hierarchical cluster analysis grouped the wild/weedy populations into three major clusters, largely according to their geographic origin. {T}he three crop populations were similar to each other and grouped with two wild/weedy populations that occurred nearby. {O}utcrossing rates among the wild/weedy populations ranged from 5-33%, indicating a variable mixed-mating system. {C}onclusion: {G}eographic isolation has played a significant role in shaping the contemporary patterns of genetic differentiation among these populations, many of which represent excellent candidates for in situ conservation. {I}n two cases, close genetic affinity between cultivars and nearby wild/weedy populations suggests that gene flow has occurred between them. {T}o our knowledge, this is the first study investigating population-level patterns of genetic diversity in wild relatives of eggplant.},
