Phenology
[drafting underway]
Suitability for cultivation and agronomic production
Autumn Royal is rather vigorous and has an erect bearing. It is not very fertile but produces large bunches. It is not very sensitive to millerandage. This variety has a moderate production that can vary from one year to the next. This variety is usually pruned long. The harvest must be performed several times as the maturity and the coloration of berries is heterogeneous and the grapes do not keep well on the vine trunks.
Susceptibility to diseases and pests
Autumn Royal is a little sensitive to peduncular rot. It is also very sensitive to downy mildew and rather susceptible to vine leafhoppers.
Technological potentiality
Autumn Royal’s bunches are large and moderately compact. The berries are seedless, very large, simple-flavored, with a moderately thick skin and a crunchy, sapid pulp. This variety does not recquire an acid gibberellic treatment and has interesting gustatory qualities. The berries are rather sugary for a table grape variety, and if the seeds are present, they are soft and not very noticeable. The bunches have a good cold storage aptitude and resist well to manipulations.
