The overall goal of this study was to evaluate the genetic diversity of reproductive characteristics of the accessions in the KSU USDA-NCGR orchards. Our hypotheses were that 1) larger trees will have greater fruit set than smaller trees; 2) trees that are higher in the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order. For longer periods of time will have more extended harvest times; 3) trees that are higher in the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of the lower order of

Plant Material Six populations of trees from different regions of the United States were selected in the KSU Germplasm Repository Orchard for evaluation of vegetative and reproductive characteristics. These populations included 10 trees from Washington Co., Ind. [(IN-1), row 2, trees 42-58]; 23 trees from Tompkins Co., N.Y. (row 5, trees 23-45), 13 trees from Tyler Co., W.V., 14 trees from Talbot Co., Md. (row 6, trees 100-120), 21 trees from Fayette Co., Ky. (row 7, trees 55-76), and 8 trees from Decatur Co., Ind. [(IN-2), row 8, trees 88-97]. Climatology data for these sites can be found in Table 5.1. Seed was collected from native stands in these six geographic regions and sown in KSU greenhouses in Spring 1994; these one-year-old seedlings were planted in the KSU orchards in Spring 1995.

2002 study Trunk diameters were measured on March 30, 2002, before spring plant growth began, with a d-tape wrapped around the trunk 30 cm from the ground, and trunk cross sectional areas (TCSA) were calculated. The number of maroon flowers on trees was counted on Mondays, Wednesdays, and Fridays from April 10, 2002 until May
