Online published on 3 May, 2025. Abstract Different exotic mandarin cultivars imported from Israel and budded on various root stocks were evaluated from 2017 to 2019. Kinnow scion grafted over Rough Lemon plant reached its maximum height (3.50 m). Fairchild budded on Volkamer lemon (3.19 m) was found to be promising in terms of average plant spread. Fairchild and Michal budded over Volkamer Lemon and X 639 produced the largest plant volume (13.30 m3). Similarly, Michal grafted on Volkamer lemon achieved the scion girth (26.8 m) and root stock girth (33.7 m). Pearl Tangelo grafted on Rough lemon produced earliest bloom initiation while there was a lot of heterogeneity among the best cultivar and root stock combinations. Daisy x Rough lemon combination proved to be the best in terms of earliest maturity with the shortest number of days from fruit set to maturity (222.3 d). Volkamer lemon and X-639 outperformed the other stionic combinations in most of the criteria, indicating that they have the potential to replace the current leader Rough lemon. Thus, it can be said that these combinations can best replace the existing Kinnow budded over Rough lemon monoculture with nearly identical features.
