Interpretive Summary: Poor cross pollination causes major economic losses in many pecan orchards. This loss is due to there being insufficient information as to which varieties do a good job pollinating certain other varieties. The traditional two-type flowering classification system, the Type I and Type II system, fails to provide enough resolution in flowering overlap patterns to be of much practical value. A new 30-class flowering classification system was developed that provides orchard managers or home owners with knowledge necessary to insure good pollination. Information is also presented comparing vegetative and reproductive characteristics of major U.S. pecan varieties. These cultivar comparisons, plus the '30-class flowering system', can be used to substantially increase pecan production and quality.
