Selected Multistate Research Projects

  • NE 009, Conservation and Utilization of Plant Genetic Resources. Impacts: 1) Preservation of important genetic resources provides ease-of-access to the plant germplasm, for example collected apple germplasm in Turkey, and made seed crop catalogs available on the Internet. 2) Completed core germplasm collections for all major seed crops.

  • NE-103, Postharvest Physiology of Fruits, and NE-183, Multidisciplinary Evaluation of New Apple Cultivars. Impact: NE-103 has enabled growers and storage facility operators to make decisions on optimum harvest times and storage conditions to best maintain fruit quality and thus increased their profitability, saved potentially millions of dollars annually by avoiding chemicals used in fruit storages, and reduced food safety risk for storage workers and consumers through reduced use of chemicals. NE-183 has given consumers a wider selection and assured high quality apples as a result of tests being done for apple varieties originating form North America, Europe, New Zealand, Australia, and Japan. NE-183 has provided information to apple producers where geographically a particular cultivar or strain is best suited, thus preventing an enormous investment of money, time, and effort by each of the apple districts throughout the United States and Canada. NE-183 has enabled the U.S. apple industry to remain competitive with foreign producers, keeping apple prices low for the benefit of consumers without sacrificing quality and profitability.

  • NE-140, Biological improvement of chestnut and management of chestnut pathogens and pests has resulted in breeding genetically resistant progeny to this formidable disease, American Chestnut Blight. NE-140 has developed a new application of the emerging biotechnologies to control a plant pathogen, without resorting to the use of pesticides.

  • W-1185, Biological Control in Pest Management Systems of Plants. Impact: Breakthroughs on the biology of Encarsia, an important group of whitefly parasitoids, suggest that symbionts (Wolbachia) and ovicidal behavior on the part of adult females can influence parasitism rates. New marking technologies and wind-tunnel studies reveal detailed information on the dispersal of whitefly parasitoids important to understanding the potential for augmentative biological control.
