The Royal Helen cherry is a strain obtained by the Zaiger’s Inc Genetics research station located in Modesto, California. The patent application for Royal Helen was filed in the United States on 1 July 2008. The variety is the result of a seed obtained from crossing Bing with Royal Dawn.
Curiosities: Being a variety of new cherry, its behavior in Spain has not been studied in depth. Viveros Ebro and Viveros Mariano Soria have multiplication permits on this variety. The varietal registration in the European Union will be valid until December 31, 2045.
Characteristics of the Royal Helen variety
Flowering: The variety of Royal Helen cherry is a variety self-fertile. It has alleles S1 and S4′. On the other hand, it is a variety of early flowering (last week of March).

Vigor and bearing of the tree: Royal Helen has a medium vigor. With a upright (virosado) bearing.
Chill hours: The breeder’s research station has calculated that it has needs of less than 750 chill hours (below 7ºC).
Morphological characteristics of Royal Helen cherry

The characteristics of a variety of cherry can undergo major changes. Type of soil, treatments, climate, altitude, date of collection, rootstock, tree load, pruning performed, subscribers, viruses, bacteria, fungi or other pathologies, framework planting, etc.
It is essential to study the different existing varieties and their behavior in the conditions present in our cultivation area. Taking advantage of the advice of engineers, farmers, technicians and professionals in the sector is essential to carry out a cherry plantation.
A significant part of the information, has been disclosed by Spanish research organizations. Therefore, the behavior of cherry tree varieties may be different depending on the growing place.
