Fruit quality characterization of wild and cultivated blackberries

Abstract

Ojetive: To characterize wild and cultivated blacberries for fruit quality to identify those with outstanding traits for genetic improvement. Design/methodology/approach: External and internal variables associated with fruit quality were evaluated in ripe blackberries. The varables evaluated were: fruit lenght, fruit width, fruit weight, fruit shape, seed area, pH, titratable acidity, and total soluble solids. Statical analysis was performed for each variable. Cluster and multivariate analysis were assessed to determine variability and relationship between the germoplasm. Results: The Rubus glaucus Benth, accession showed values similar to cultivated varieties in lenght, width, and fruit weight, number of drupelets per fruit, pH, and total soluble solids, while the Rubus philyrophyllus Rybd. acc ession exhibited values similar to cultivated varieties in seed area, pH, titratable acidity, and total soluble solids. One classic variety and three contemporary varieties stood out with large, heavy fruits and more drupeoles, and one commercial variety and the highest total soluble solids. Fruit quality characterization of wild and cultivated blacberries in an initial an essential step to identify germoplasm with outstanding traits. Integrate this species into breeding programs will contribute to broading the genetic base and incorporate their favorable alleles, actions that contribute to their utilization by humans and their conservation. The characterization allowed to identify the R. glaucus Benth and R. philyrophyllius Rydb. wild species with outstanding traits, which facilitates their appreciation and integration unto breeding programs.
