Wild biotypes of fruit tree species represent important genetic resources for improving adaptability and yield under low-input conditions. In Constanta and Arges counties, several cherry plum biotypes were identified and characterized in terms of plant habit, vigor, health status, and fruit quality. Most fruit samples exhibited high dry matter content, exceeding 15° Brix, and were classified as sweet or very sweet. The most promising rootstock selections will be grafted and included in the National Collections, serving as a gene reservoir for future breeding programs.Englishbiotypesmyrobalan plumevaluationfruitArticle2069-8275
