1 University of Wisconsin Urban and Regional Food Systems 2015 Vegetable Variety Screening Trials WINTER SQUASH and PUMPKIN Trial Notes: All varieties planted June 3, Planted in mounds and mulched with chopped alfalfa hay. High incidence of Angular Leaf Spot in early season. No significant varietal difference in disease resistance. Four plants per mound and 12 ft between mounds.

5 Variables factor map (PCA) Dim 2 (16.10%) bitterness acidity saltiness color texture sweetness Dim 1 (77.03%) Representation of quality characteristics, based on crew evaluation, resulting from a principal component analysis of all crew quality evaluation data. The length of the arrow for each characteristic is proportional to its contribution to the variation among varieties, and the direction of the arrow is in the direction of increasing scores for that characteristic. This shows how related the characteristics are to each other, and is also used to read the following graph of varieties. The individual (variety) factor map on the next page plots where each variety lands relative to these quality components 36

6 Individuals factor map (PCA) E30R.079 Tiana Dim 2 (16.10%) E30R Nutterbutter Potimarron Havana Butterscotch Doran E30R Orange Summer Dim 1 (77.03%) Representation of varieties, based on crew evaluation, resulting from a principal component analysis of all crew quality evaluation data. The position of each variety shows how it was evaluated for the di erent quality characteristics on the previous page. For example, a variety that near or beyond the end of the color arrow would show particularly intense color and a variety on the opposite side of the graph than the direction in which the color arrow points would have poor color. This can be done for each of the quality characteristics. This graph also shows how varieties are related to each other for the complete set of quality characteristics, and characteristics that contributed more to the variation among varieties have greater weight in determining where varieties are positioned on the graph. This can be helpful in making selections based on multiple characteristics at once. This graph helps us select which varieties we send to the group of chefs we are working with for further quality evaluation 37
