This new variety of blackberry when grown under normal horticulture practices in a greenhouse possesses the distinctive combination of traits:
- High yield up to 75 t/ha
- Huge fruit up to 17-18 g
- Very sweet taste with a limited amount of acids
Harvest season starts at the end of May and continues until the end of August when grown in closed high tunnels, so in open ground crop is expected from the beginning or middle of June.
Fruit have oblong or long-conical shape (up to 40 to 45 mm or longer, diameter up to 30 mm) and a large number of drupelets. Fruit stem is covered with a lot of small hairs. Fruit weight is 12 g, but some berries can grow up to 17-18 g. The fruits of Jandrie blackberry have small hairs, taste of is very sweet.
Fruiting laterals start producing fruit more quickly from the top to the bottom of the plant, hence a high production capacity is quickly obtained after the beginning of the fruit ripening. The fruit production continues for a longer period thus resulting in the high yield. Yield is extremely high, up to 65-75 tons/ha under optimal conditions in closed high tunnels (typical was 55 tons/ha).
Storability is excellent, Jandrie can be stored 7 to 8 days in a cold storage room. Can also be stored relatively long on the shelf, with the fruit remaining glossy and red drupelet reversion.
Jandrie can be propagated by stem and root cuttings, tissue culture. Jandrie show high resistance to downy mildew.
