The advanced selections, NCS 10-038 and NCS 10-156, from the North Carolina breeding program were compared to the traditionally used cultivars, Camarosa and Chandler, for storage life and fruit composition in 2014 and 2015. Postharvest quality of NCS 10-038 was similar to that of ‘Camarosa’ and ‘Chandler’ after 8 days storage at 4 °C. NCS 10-156 was significantly worse in overall appearance and had more fruit shrivel, calyx browning, and mold than the other genotypes. However, NCS 10-156 was highest in soluble solids content and was similar in total anthocyanin content and total phenolic content to ‘Camarosa’ and ‘Chandler’. Further analysis of flavonoids by high performance liquid chromatography showed that NCS 10-156 was much lower in total flavonols than the other genotypes and comparable in anthocyanin pigments to ‘Chandler’. NCS 10-038, while similar in pigment profile to ‘Camarosa’, had less total anthocyanin than the other genotypes. NCS 10-038 had a lighter red color than the other genotypes and was similar in postharvest quality to ‘Chandler’ and ‘Camarosa’ and may be suitable for long-distance markets. NCS 10-156 is slightly softer than the other genotypes and more prone to mold while the higher soluble solids content may make it suitable for direct market sales. Both selections show postharvest promise for strawberry production in the humid mid-South region.
