http://www.hort.cornell.edu/reisch/grapegenetics/breeding/crossing1.html WebConsistent classifications were produced for the precocity for budbreak, flowering, veraison and maturity. However, some results do not seem to fit with field observations. A more sophisticated agro-climatic model is necessary to improve the accuracy of this classification of precocity of grapevine varieties. References BAGGIOLINI M., 1952.
