Apple tree - Rubinstar variety

Abstract

A new and distinct variety of apple tree is provided which forms quality fruit having an attractive substantially uniform red coloration. The new variety originated in the Federal Republic of Germany as a mutation of the Jonagold variety. The fruit of the new variety can be distinguished from that of its mother variety by the exhibition of a more intense red coloration which covers a greater portion of the fruit surface in the substantial absence of striping. Also, the new variety forms fruit which colors approximately one week earlier than its parent. Such improved fruit coloring propensity is deemed to be of substantial commercial importance.

I claim: 
     
       1. A new and distinct variety of apple tree which is a mutation of the Jonagold variety, substantially as illustrated and described, having the propensity to form fruit exhibiting a more intense red coloration which covers a greater portion of the fruit surface than its mother Jonagold variety, forms fruit which colors approximately one week earlier than its mother Jonagold variety, forms fruit having greater coloration than the earlier reported mutation of U.S. Plant Pat. No. 5,937 in the substantial absence of striping, forms fruit which is significantly darker in coloration than the earlier reported mutations of U.S. Plant Pat. Nos. 6,148 and 7,146, and exhibits a more compact growth habit than the mother Jonagold variety and its other previously reported mutations.
