- shoots are characterized by good ripening and fruiting in 50-70%;
- the average number of clusters per shoot is 1.3-1.6;
- indicators of average productivity reach 130-150 kg / ha;
- frost resistance and immunity to diseases standard for European grapes;
- the prevalence of mildew and oidium is medium;
- susceptibility to gray rot is low;
- average transportability;
- the marketability of the crop is high;
- pleasant taste and aroma with a muscat shade;
- possibility of use for arched formations.
Excellent taste indices allow this variety to occupy the first places at tastings, due to which we can safely attribute the "Radiant mushrooms" to the best selection achievements in the category of seedless varieties.
Grapes "Radiant raisins": growing
