Table 1. Summary of sequenced blackberries from the University of Arkansas System Division of Agriculture (UA) and the USDA-ARS Horticultural Crops Research Unit (HCRU) breeding programs. Mean historical soluble solids content (SSC), circular consensus sequences (CCS) generated during sequencing are presented, and groupings determined via K-means clustering using markers identified from the Hillquist V1 (HV1) and R. occidentalis V3 (RoV3) genome assemblies.
