The olive is a fruit tree species with a century-old history of cultivation in theMediterranean basin. In Apulia (Southern Italy), the olive is of main social, cultural and economicimportance, and represents a hallmark of the rural landscape. However, olive cultivation in thisregion is threatened by the recent spread of the olive quick decline syndrome (OQDS) disease, thusthere is an urgent need to explore biodiversity and search for genetic sources of resistance. Herein,a genetic variation in Apulian olive germplasm was explored, as a first step to identify genotypeswith enhanced bio-agronomic traits, including resistance to OQDS. A preselected set of nuclearmicrosatellite markers allowed the acquisition of genotypic profiles, and to define geneticrelationships between Apulian germplasm and widespread cultivars. The analysis highlighted thebroad genetic variation in Apulian accessions and the presence of different unique genetic profiles.The results of this study lay a foundation for the organization of new breeding programs for olivegenetic improvement.
橄榄是一种果树品种，在地中海盆地有着百年的种植历史。在普利亚（意大利南部），橄榄具有重要的社会、文化和经济意义，是乡村景观的一个标志。然而，该地区的橄榄种植受到最近橄榄快速衰退综合征（OQDS）疾病传播的威胁，因此迫切需要探索生物多样性并寻找抗性基因源。在此，作为鉴定具有增强生物农艺性状（包括对OQDS的抗性）的基因型的第一步，对普利亚橄榄种质的遗传变异进行了探索。一组预先选定的核微卫星标记能够获取基因型图谱，并确定普利亚种质与广泛种植品种之间的遗传关系。分析突出了普利亚种质中广泛的遗传变异以及不同独特基因型的存在。本研究结果为组织新的橄榄遗传改良育种计划奠定了基础。
