Apple tree named ‘UEBI 406/1’

Abstract

A new and distinct Malus domestica (Borkh.) variety that exhibits a slightly upright to spreading tree habit, medium-high vigor, medium dense pyramidal tree form, bears a V.sub.f-resistance gene against scab, and has high and regular yields without the need of fruit thinning. The new variety provides late maturing, medium-sized, cylindrical globose-shaped, and homogenous bright red fruits that are russet free. The fruit flesh is firm, crisp, and juicy, with a finely sour and slightly aromatic flavor. The fruits of the new variety exhibit good eating and keeping qualities.

Claims

1. A new and distinct variety of Malus domestica (Borkh.) apple tree plant substantially as is herein described and illustrated.
