Cultivation

Origin: in Fort Valley, Ga., by John H. Weinberger, U.S. Dept. of Agriculture Hort. Field Sta. Introd. in 1954. Newday × Southland; cross made in 1946; tested as USDAFV 177-17. Tree: vigorous; unproductive in some areas; susceptible to late spring frost; less bacterial spot than Southland and Elberta; flower small, self-fruitful, blooms about the same time as Newday and Southland in the Fort Valley area; leaf glands globose; chilling requirement 750 h. Fruit: about the same size as its parents; round; skin with a light attractive blush over bright golden ground cover, pubescence light; flesh yellow, firm, smooth textured, flavor good; pit very nearly free, resembling Newday and slightly less free than Southland; ripens with Early Hiley, slightly ahead of Triogem, or 3 to 3 1/2 weeks ahead of Elberta.
