Abstract

The present invention relates to a new and improved variety of apricot tr The fruit of the new variety is characterised by attractive bright orange color with a pink-red blush, medium size, and firm flesh with an excellent sweet flavor. The tree is characterised by moderately vigorous healthy growth and spreading to upright tree habit. The new variety has been named `Alex`.

Description

ORIGIN OF THE VARIETY
The new and distinct variety of apricot tree (Prunus armeniaca) was selected from a population of approximately 2000 seedlings originated by Dr. Ron Beatson in 1986. The seedlings were grown on a site near Clyde, Central Otago, New Zealand's major apricot growing area. The seedlings began to fruit in 1990, and were evaluated for tree health and fruit flavor, and to a lessor extent skin finish, size and color. In 1993, 49 elite seedlings were selected by Dr. Dominique Noiton from this population and grafted onto rootstocks for further evaluation. One of the seedlings, an open-pollinated seedling of `CluthaGold` (a New Zealand variety that has been granted Plant Variety Rights in New Zealand on Jun. 16, 1988 under Grant No. 411, and in France on Jan. 2, 1997 under Grant No. 09961) showed desirable commercial characteristics after initial evaluation and was propagated for further trials. Furthermore the new and distinct variety has been named `Alex`.
The present new apricot tree was first asexually propagated at Clyde, Central Otago, by budding onto Golden Queen peach rootstocks, the standard apricot rootstock in New Zealand. Seedling rootstocks are routinely used in New Zealand for ease of propagation. "Golden Queen" is a peach (Prunus persica) variety that is commonly used because it is readily available and easily propagated from stones. It is a relatively vigorous stock that imparts vigor to the scion variety similar to that of trees on their own roots. It also imparts some tolerance to bacterial diseases such as Pseudomonas syringae. The resulting trees have propagated true-to-type showing that the distinctive characteristics are established and transmitted successfully through succeeding generations.
DESCRIPTION OF THE VARIETY
The new and distinct variety of apricot tree is of medium size, moderately vigorous spreading-upright growth, and is a regular and productive bearer of medium sized, firm, juicy fruit with sweet flavor and excellent eating quality. The fruit is further characterised by late season ripening. `Alex` is similar in appearance to the apricot `CluthaGold`, however, `Alex` has a higher amount of red blush, is more flavorsome, and furthermore, ripens 2-3 weeks after `CluthaGold`.
BRIEF DESCRIPTION OF THE ILLUSTRATION
The accompanying photograph shows typical specimens of fruit and foliage of the new variety shortly after picking at commercial harvest maturity. The fruit is shown in side view with the suture facing up (top right), view of the apex end (bottom right), side view (top left), view of the stem end (bottom left), a view of the fruit split along the suture line (top middle), and a view of the stone.
