McHaley, too, believes the two short cherry crops in a row have slowed down interest in more cherries. At Dave Wilson Nursery, a couple of cherry variety favorites of growers have been Royal Lynn and Royal Tioga, both low-chill varieties. Royal Lynn is a new, very early cherry, ripening in early to mid-May in the Fresno region. Fruit are medi- um-large in size, mahogany red colored, and firm with long stems. Royal Lynn is not prone to cracks, spurs, or doubles, according to McHaley, and requires 500 chilling hours. Royal Tioga has been popular because of its good size, early harvest, sweet flavor, and self fertility, he said. Stone fruit trends Planting trends in stone fruit have been yellow and white fleshed for peaches and nectarines, with slightly higher sales of yellow-fleshed nectarines, McHaley said. Growers are especially interested in red-fleshed plu- ots, like Festival Red, Crimson Rose, Ebony Rose, and Honey Punch, he said. Late-season apricots that pick into the middle of August have also been popular. The trend of planting low-acid nectarine varieties has been growing. Zaiger Genetics, the breeder of vari- eties sold by Dave Wilson Nursery, has released nine yellow-fleshed, low-acid nectarine varieties under the Honey name, like Honey Haven, Honey Kist, and Honey May. Some are freestone varieties, some clingstone. In looking toward the short-term future, McHaley believes the next five years will be strong for stone fruit growers. "With almond taking up what was tree fruit ground, marketing for a grower profit will be easier," he said. "Labor issues are always a concern, but with better prices, labor should be manageable." • WHAT A Gem! G em, a new fire blight- resistant pear vari- ety from the U.S. Department of Agricul- ture's breeding program, was officially released this spring. The pear is medium sized with light green skin that turns to yellow when ripe. The skin can have up to 35 percent red blush. It does not russet under dry growing conditions, and only occasionally in humid conditions. Gem originated from a cross of Sheldon and US62563-004 made in 1970. It was selected in 1981 from the USDA's seedling orchard at Beltsville, Mary- land, by Dr. Richard Bell. He tested it extensively at the Appalachian Fruit Research Station in West Virginia, where he is pear breeder. In West Virginia, Gem blooms about a day before Bartlett and harvest begins about a week after Bartlett. It can be harvested over an extended period. The flavor is sweet to subacid and mildly aromatic. The variety is precocious, bearing fruit three years after planting, and produces high yields, accord- ing to the USDA. It has been tested at Oregon State University, Washington State University, Clemson University, and Michigan State University. Trees of Gem are not available yet, and budwood is limited. For more information, contact Bell at richard. Budwood with virus-free and phytoplasm-free certi- fication will be available from the Clean Plant Center of the Northwest at Washington State University, Prosser. Genetic material of Gem will be deposited in the National Plant Germplasm System, where it will be available for research purposes, including development of new cultivars. —G. Warner Gem is a new fire blight resistant pear that tends not to russet.
