High Variation in Yield among Wild Blueberry Genotypes: Can Yield Be Predicted by Leaf and Stem Functional Traits?

Wild lowbush blueberry fields are characterized by high genetic diversity, with a large number of genotypes coexisting in every field. Yield also varies among genotypes, which could be related to the variation physiological and structural traits, but this has not been rigorously tested. In study, we aimed quantify inter-genotype yield, as well leaf stem functional establish relationship between traits yield-related wild blueberries. To do so, carried out study during 2019 harvest season measuring including number, length, diameter, chlorophyll concentration, mass area, area per stem, branches temperature, soil water content yield data berry size (weight 100 berries), berries length cluster from two farms. We found variations structural, functional, fields. negative associations unit midday temperature whereas concentration was positively associated yield. Additionally, quadratic berries, cluster) optimum for at 25 cm. Our results suggest that several traits; thereby, those can used predict yields. findings help growers breeders select better-yielding based on traits.
