Cultivation

Origin: at Watsonville, Calif., by RS. Bringhurst and Victor Voth, Agr. Expt. Sta., Univ. of Calif., Davis. Introd. in 1979. Plant patent 4487, 20 Nov. 1979; assigned to Regents, Univ. of California, Davis. 64.57-108 (Tioga × Sequoia) × Tufts. Tree: larger than Tioga; leaflets exceptionally large, less green than those of Tioga; highly productive; as susceptible to verticillium wilt as Tioga, Tufts, and Aiko; highly susceptible to red stele (Phytophthora fragariae). Recommended for commercial production in southern California as an early, high-quality, winter-planting variety and as an improved summer-cropping variety for the central coast. Named for the late Malcom B. Douglas, manager of California Strawberry Advisory Board. Fruit: larger than that of Tioga; flesh quality and flavor equal or superior to those of Aiko, Tioga, and Tufts; skin resembles that of Tufts, but redder.
