Apple tree named ‘Dalirail’

Abstract

A new and distinct Gala-type apple cultivar is disclosed. The new cultivar ‘Dalirail’ arose as a whole tree mutation of ‘Imperial Gala.’ ‘Dalirail’ is notable for its intense coloration and early maturity as compared to its parent and to other known Gala cultivars.

Description

Latin name of the genus and species of the plant claimed: Malus pumila Mill.

Variety denomination: ‘Dalirail’.

BRIEF DESCRIPTION OF THE VARIETY

‘Dalirail’ originated as a whole tree mutation of ‘Pinova’ (U.S. Plant Pat. No. 11,601). The original tree mutation was discovered during the 1998 harvest in a commercial block of ‘Pinova’ trees near Lezigne, France, planted on M9 rootstock (not patented) in 1997. The new variety was first asexually propagated by grafting in February 1999 for testing purposes at Doue La Fontaine, France under breeder's reference number MN R36 A6.

The asexually propagated progeny of ‘Dalirail’ have been found to be homogeneous and stable, retaining the unique characteristics of the original ‘Dalirail’ tree, and remaining true to type through successive generations of asexual propagation.

‘Dalirail’ is similar to its parent ‘Pinova’ in some respects, such as its ability to withstand winter and spring frosts; desirable flavor as a dessert quality fruit; very little or no russeting; no alternate bearing; and good storageability. However, ‘Dalirail’ is distinguishable from its parent by a number of features. The tree of ‘Dalirail’ has been observed to be more vigorous than ‘Pinova’ in side by side growing trials. Branches of ‘Dalirail’ are longer than those of ‘Pinova.’ The fruit of ‘Dalirail’ further distinguishes the new variety from its parent. A comparison of the fruit of ‘Dalirail’ and ‘Pinova’ is set forth in Table 1 below.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following is a detailed botanical description of ‘Dalirail,’ a new and distinct cultivar of Malus pumila Mill., based on observations made on the original tree from 2001 to 2004, and during the 2001 through 2005 growing seasons on specimens of the second generation planted at Angers, France in 2001. All colors are described according to The Royal Horticultural Society Color Chart. It should be understood that the botanical and analytical characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from 2 year old trees of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average.
