Apple tree named ‘Jugala’

Abstract

‘Jugala’ is a Gala-type apple characterized by its early harvest date as compared to other known Gala varieties.

Description

Latin name: Malus domestica Borkh.

Variety denomination: ‘Jugala’.

BACKGROUND OF THE VARIETY

‘Jugala’ is a new and distinct variety of apple tree Malus domestica Borkh. This new variety is a naturally occurring whole tree mutation of ‘Mitchgla’ Gala (not patented). ‘Jugala’ was first observed in an orchard located at Saint Paul D'Espis, near Montauban in the Tarn et Garonne region of southwest France, and was selected because of its advanced coloring as compared to the surrounding ‘Mitchgla’ trees. ‘Jugala’ was asexually reproduced by budding and fruited through two successive generations in two different locations in France (Seiches sur Le Loir and VillersCotterets) and has been observed to remain true to type over successive asexually propagated generations.

BRIEF DESCRIPTION OF THE VARIETY

‘Jugala’ was first noted and selected for its early fruit maturity. ‘Jugala’ matures about five days earlier than most other known Gala varieties, ‘Mitchgla’ in particular. The early maturity is well characterized by a higher starch regression at harvest time, as well as a higher level of sugar and a reduction of firmness. These distinctive characteristics are shown in following tables. The comparisons were made on trees of the same age, planted in the same orchard, located in the same row side by side. All trees were planted on ‘Lancep’ M9 rootstock (U.S. Plant Pat. No. 7,714). Starch regression was determined using the “CTIFL Starch Conversion Chart for Apples” (G. Planton, France).
