Fruit from genotypes of southern highbush blueberries ( Vacciniumspp.), and 'Sierra' were compared for postharvest quality. Commercially important rabbiteye (cv. Climax) and northern highbush (cv. Bluecrop) were included as standards. 'Gulfcoast,' 'Cooper' and 'Cape Fear' fruit retained 10-20% of pedicels after harvest ('stemming') while very few pedicels were retained on other cultivars. Fruit from the selection G616 were greatest in weight (2.8g) and 'Cooper' the smallest (1.7g). A109 fruit had the smallest stem scar and MS108 the largest. 'Sierra' and 'Climax' fruit had the least decay among all clones. G616 fruit were the least firm of all clones after storage. Soluble solid concentration/titratable acidity ratios were between 10 and 19 for all clones. Anthocyanin content was highest in 'Cape Fear' and lowest in MS108. Of the new southern highbush clones, 'O'Neal,' G616 and A109 cultivars were equal to or better than 'Bluecrop' or 'Climax' in postharvest quality and shelf life.
