![]() The program will then analyze that data to determine which traits are more or less important in predicting overall quality, partly by prioritizing traits that are easier to judge objectively, such as size or color. ![]() Using the software, breeders can select traits and ask multiple people to perform the same evaluation. RateRvaR is freely available, open source, easy to use and applicable to breeders of any vegetable, tree or flower with subjective features. Now a Cornell group – doctoral student Zachary Stansell Thomas Björkman, professor of horticulture at Cornell AgriTech and Deniz Akdemir of the Cornell Statistical Consulting Unit – has released RateRvaR, a new software based on this method. A head of broccoli that might appeal to one person – perhaps because of its deep green color – may leave another cold, due to an asymmetrical shape or too-large buds.Ĭornell researchers participating in the Eastern Broccoli Project, which aims to produce broccoli varieties suited to grow on the East Coast, have devised a statistical method to standardize evaluations of broccoli, in order to make plant breeding decisions more consistent and efficient.
