Conversely, excessive demand for high quality is causing \u201cseed loss and waste\u201d due to slight shortfalls in eligibility rates. In this study, we applied near-infrared imaging spectrometry combined with machine learning techniques to evaluate germinability and paternal haplotype in crop seeds from 6 species and 8 cultivars. Candidate discriminants for quality evaluation were derived by linear sparse modeling using the seed reflectance spectra as explanatory variables. To systematically proceed with model selection, we defined the sorting condition where the recovery rate of seeds matches the initial eligibility rate (\n                    <jats:italic>iP<\/jats:italic>\n                    ) as \u201cstandard condition\u201d. How much the eligibility rate after sorting (\n                    <jats:italic>P<\/jats:italic>\n                    ) increases from\n                    <jats:italic>iP<\/jats:italic>\n                    under this condition offers a reasonable criterion for ranking candidate models. Moreover, the model performance under conditions with adjusted discrimination strength was verified using a metric \u201crelative precision\u201d (\n                    <jats:italic>rP<\/jats:italic>\n                    ) defined as (\n                    <jats:italic>P\u2013iP<\/jats:italic>\n                    )\/(1\n                    <jats:italic>\u2013iP<\/jats:italic>\n                    ). Because\n                    <jats:italic>rP<\/jats:italic>\n                    , compared to precision (=\n                    <jats:italic>P<\/jats:italic>\n                    ), is less dependent on\n                    <jats:italic>iP<\/jats:italic>\n                    in relation to recall (\n                    <jats:italic>R<\/jats:italic>\n                    ), i.e., recovery rate of eligible seeds, the\n                    <jats:italic>rP-R<\/jats:italic>\n                    curve and area under the curve also offer useful criteria for spotting better discriminant models. We confirmed that the batches of seeds given higher discriminant scores by the models selected with reference to these criteria were more enriched with eligible seeds. The method presented can be readily implemented in developing a sorting device that enables \u201clast-percent improvement\u201d in eligibility rates of crop seeds.\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0291105","type":"journal-article","created":{"date-parts":[[2023,9,20]],"date-time":"2023-09-20T13:22:46Z","timestamp":1695216166000},"page":"e0291105","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["Last-percent improvement in eligibility rates of crop seeds based on quality evaluation using near-infrared imaging spectrometry"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-6905-6686","authenticated-orcid":true,"given":"Osamu","family":"Matsuda","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshinori","family":"Ohara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,9,20]]},"reference":[{"key":"pone.0291105.ref001","unstructured":"United Nations.
