The first cultivar(培育植物) of 'ōhelo berry, a popular native Hawaiian fruit, has been released by U.S. Department of Agriculture (USDA) scientists and their university and industry cooperators. 'Ōhelo (Vaccinium reticulatum Smith) is a small, native Hawaiian shrub1(灌木) in the cranberry2(蔓越橘) family, commonly found at high elevations3 on the islands of Maui and Hawaii. As people scour4(擦,冲刷) the landscape to harvest this delectable5 berry for use in jam, jelly and pie filling, they unfortunately disrupt the fragile habitats where this plant grows.

In an effort to reduce damage to the environment and meet consumer demands, horticulturist Francis T.P. Zee, with the USDA Agricultural Research Service (ARS) Pacific Basin Agricultural Research Center (PBARC) in Hilo, Hawaii, is evaluating 'ōhelo for small farm production and ornamental6 use. Zee collaborated7 with fellow ARS scientists and cooperators at the University of Hawaii at Manoa, Big Island Candies and the Big Island Association of Nurserymen. ARS is the principal intramural(内部的) scientific research agency of USDA.

Zee and his team selected the offspring of seed-grown plants to create the new cultivar "Kilauea" for berry production. They found 'ōhelo's tiny seeds readily germinated8 under 20-30 percent shade in well-watered and well-drained potting mixture. Plant hardiness9 and vigor10 improved with age, and some seedlings11 flowered just 10 months after germination12, much sooner than the 5 years reported in previous studies. The 16-month-old plants Zee successfully transplanted from the greenhouse to the field produced berries a year later.

Zee also used cuttings and tissue culture to propagate selected 'ōhelo of high ornamental(装饰的) potential. With proper care, young, growing shoots of 'ōhelo can be groomed13 into vibrant14, colorful ornamental potted plants. Since the plant is not seasonal15, its readiness for market can be scheduled by trimming and fertilizing16. Older potted 'ōhelo plants can be trained into a bonsai17(盆栽) and can readily adapt to the office environment.

Zee and PBARC scientists are currently examining the disease and insect problems associated with growing potted 'ōhelo. Full descriptions of Zee's 'ōhelo studies can be found on the University of Hawaii's College of Tropical Agriculture and Human Resources' (CTAHR) website.
