Although\n                    <jats:italic>Saccharum spontaneum<\/jats:italic>\n                    harbors valuable genetic diversity, its systematic utilization in breeding remains limited by a lack of multi-environment evaluations. Therefore, 100 Asian\n                    <jats:italic>S. spontaneum<\/jats:italic>\n                    clones were assessed across six environments (two locations \u00d7 three crop cycles) during 2022\u20132025 using an integrated framework that combined BLUP breeding values, AMMI-based stability indices (ASV, GSI, HMRPGV, WAASB), and the multi-trait selection index MGIDI. Heritability, repeatability, and genetic correlations were estimated to support selection decisions. Moderate heritability was observed for stalk diameter and stalk height, while juice Brix and stalk weight showed low heritability. The clones were classified into four heterotic groups; only three clones (C059, C086, and C089) met both high-performance and high-stability thresholds, forming Group A (elite + stable). Group B (high performance, low stability) included 22 clones, Group C (low performance, high stability) included 22 clones, and Group D (moderate) comprised the remaining 53 clones. Repeatability from first to second ratoon was remarkably high (\u22650.90) for most morphological traits, except stalk weight (0.07). Genetic correlations revealed a trade-off between juice Brix and internode length, and a positive association between tillering rate and fresh biomass. Crossing strategies should prioritize Group A \u00d7 Group B and crosses between geographically distant origins (e.g., Yunnan \u00d7 Hainan) to maximize heterosis. The three elite clones are recommended as immediate parents for climate-adaptive breeding programs.\n                  <\/jats:p>","DOI":"10.3389\/fpls.2026.1923174","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T13:08:52Z","timestamp":1790600932000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Breeding values, stability, and heterotic grouping of Asian Saccharum spontaneum collection for parental selection in sugarcane program"],"prefix":"10.3389","volume":"17","author":[{"given":"Chao-Hua","family":"Xu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Tropical Crop Breeding, Sugarcane Research Institute, Yunnan Academy of Agricultural Sciences, Yunnan Key Laboratory of Sugarcane Genetic Improvement","place":["Kaiyuan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farrag F.
