Characterization And Inheritance Assessment Of Fruit And Leaf Shape In Unique Vitis Seedlings, Paul J. Sandefur, John R. Clark, Douglas Karcher
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
From August to October of 2009, two separate studies were conducted to assess fruit shape of Vitis section Euvitis hybrid bunch grapes using digital photography (Study 1) and evaluate inheritance of leaf shape in unique populations of V. rotundifolia hybrids (Vitis section Muscadinia) (Study 2). All vines studied were located at the University of Arkansas Fruit Research Station, Clarksville. Study 1 used SigmaScan® digital photography analysis software to calculate shape factor, major:minor axis ratio, and compactness of highly variable, unique-shaped fruit from a population of 182 Euvitis seedlings. SigmaScan® accurately characterized fruit shape elongation as had been recorded in previous …
