This research focused on canopy reflectance for cultivar recognition in an olive grove. The ability in cultivar recognition of 14 vegetation indices (VIs) calculated from reflectance patterns (green520\u2013600, red630\u2013690 and near-infrared760\u2013900 bands) and an image segmentation process was evaluated on an open-field olive grove with 10 different scion\/rootstock combinations (two scions by five rootstocks). Univariate (ANOVA) and multivariate (principal components analysis\u2014PCA and linear discriminant analysis\u2014LDA) statistical approaches were applied. The efficacy of VIs in scion recognition emerged clearly from all the approaches applied, whereas discrimination between rootstocks appeared unclear. The results of LDA ascertained the efficacy of VI application to discriminate between scions with an accuracy of 90.9%, whereas recognition of rootstocks failed in more than 68.2% of cases.<\/jats:p>","DOI":"10.3390\/rs11101242","type":"journal-article","created":{"date-parts":[[2019,5,24]],"date-time":"2019-05-24T11:20:46Z","timestamp":1558696846000},"page":"1242","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["Remotely Sensed Vegetation Indices to Discriminate Field-Grown Olive Cultivars"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8353-1784","authenticated-orcid":false,"given":"Giovanni","family":"Avola","sequence":"first","affiliation":[{"name":"Trees and Timber Institute (IVALSA), National Research Council (CNR), Via P.
