The Plant Genetic Resources Unit (PGRU) was the site of a public open house on Saturday, September 18, 2004 in honor of the 50th Anniversary of the USDA's   Agricultural Research Service.  The Unit is one of the 33 components of the National Plant Germplasm System, a nationwide cooperative effort by federal, state and private organizations to preserve the genetic diversity of plants, and as such, houses approximately 12,000 D. Sharman giving vegetable crops tourvegetable varieties and 5,000 grape, apple and tart cherry varieties.  Most of PGRU's 38 employees were there to lend a hand or answer questions, with help also coming from Josh Tennies and  Anna Dellefave (leaf printing), Jan Forsline (Apple Videos) and Mary Jean Welser (liquid nitrogen demonstration).  Tours of the orchards, vineyards, rootstock nurseries, apple core collection (a sample of 200 very diverse apples), and the vegetable plantings were experienced by approximately 350 people.  In a separate tent, a demonstration of small-scale seed production was on-going throughout the day from the Public Seed Initiative.  The only "live" attraction was also under this tent with the famous honey bee observation hive.  Children and adults alike are mesmerized by the workings of the honey bee and an unobstructed view of the inside of a hive. 


Tomato seed cleaningUnder the larger tent, there were also: 1) demonstrations of how apple buds are stored in liquid nitrogen as well as the process for propagating trees from these buds by grafting; 2) demonstrations of various ways to propagate and graft  apple trees; 3) displays of fruit and vegetable diversity; 4) videos describing PGRU's work on apple; 5) hands-on DNA extraction; 6) microscopes for looking at grapes with downy-mildew and botrytis fungus; and 7) state-of-the-art research posters in vegetable diversity and fruit breeding and genomics.   Connie Rodriguez and Dan Fessenden (Executive Director) of the Ag-TechPark also joined us with their display and answered many questions regarding the upcoming park. 


There were four tours that were on-going on an hourly basis: 1) the clonal crops tour given by Phil Forsline show-P. Forsline Clonal Crop Tourcased the apple, grape and tart cherry material maintained  by the PGRU with emphasis on the wild apple trees with origin in Kazakhstan that are now fruiting; 2) the vegetable crops tour with Dave Sharman, Paul Kisly and Dr. Larry Robertson show-cased the cabbage, onions and tomatoes regenerated this year; 3) the rootstock breeding tour given by Todd Holleran explained the apple rootstock breeding program of Dr. Gennaro Fazio; and 4) Bill Srmack gave the apple core collection tour with the "blue apple" question coming up the most! (This relates to the many people in attendance that had read "The Botany of Desire" by M. Pollan where the blue apple, which is actually has reddish-purple flesh, is mentioned). 


Many thanks go to the Communications Department for their help and many ideas to organize and promote the event; design the artwork, create the database for web registrations and record the day by photographing various events.  Thanks also to Buildings and Properties in setting up tents and barricades, putting up signs, running water and electric, providing security, and making sure the grounds looked as good as they always do.  Thanks to everyone else that helped in any way, big or small.
