Katie, a Vesta practicum student working with John Avery (MSU) and Jeff Wheeler (Rend Lake), took a cluster sample of the Traminette today at approximately 1200 Growing Degree Days in order to estimate the crop in the block. Several grape cultivars have proven to reach 1/2 of their ultimate size at 1200 GDD. The 50 cluster sample weighed 8.25 pounds. She will be working at the experiment station through October so she will see how close her estimate came to the actual harvest this year.
