Apple tree named ‘R203’

Abstract

‘R203’ is a new variety of apple tree selected for its distinctive and flavorful red and yellow-white fleshed fruit, which is well-suited for the fresh market.

Description

Latin name: Malus domestica.

Variety denomination: ‘R203’.

BACKGROUND OF THE VARIETY

‘R203’ is a new and distinct variety of apple tree (Malus domestica) obtained from a controlled cross of ‘HY52’ (female parent, not patented) x ‘Scifresh’ (male parent, U.S. Plant Pat. No. 13,888) carried out at Seiches sur le Loir, France in 2003. Seeds obtained from the cross were planted at Seiches sur le Loir, and ‘R203’ was selected from the resulting seedlings for propagation and further observation. ‘R203’ was first asexually propagated by grafting at Seiches sur le Loir in 2004, and has since been observed to remain true to type through successive asexually propagated generations.

BRIEF DESCRIPTION OF THE VARIETY

The ‘R203’ apple tree is distinguished by its sweet red and yellow-white fleshed fruit. Comparisons of ‘R203’ to its parents and to similar variety ‘R201’ (U.S. Plant Pat. No. 28,218) are shown in Tables 1, 2 and 3 below.
