First note of QTL mapping of low vigor traits using the updated F2 'Koroneiki' linkage map of olive.

ABSTRACT: The olive tree (Olea europaea L.), which characterizes the agriculture of the Mediterranean basin, faces challenges adapting to high-density orchards and mechanized cultivation. This study addresses a key issue: controlling tree size to enhance efficiency and manageability in olive cultivation. Utilizing genetic mapping methods, we have identified significant Quantitative Trait Loci (QTL) and candidate genes associated with low-vigor traits in olive trees. Our research on the 'Koroneiki' F2 progeny, which exhibits low vigor traits but remains underutilized in breeding programs, has pinpointed a QTL linked to trunk basal diameter-a trait correlated with plant height based on morphological measurements. Results underscore a strong genetic control of these traits, with a consistent cor
