Peach variety named "Southern star"

Abstract

A new and distinct variety of peach tree (Prunus persica), named ‘Southern Star’, is described. The new variety is a selection derived from the open pollinated seed of ‘Yumyeong’ (not patented) and is distinguishable from the parent variety by ripening 1 week earlier than ‘Yumyeong’ and having sweeter, more aromatic fruit. Its novelty consists of a unique combination of features that include late flowering, heavy and regular cropping, large, very firm, white flesh, crisp-textured, clingstone fruit with a red overcolour. Fruit have a sweet, sub-acid flavour.

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims benefit of New Zealand PVR Application SFM 104, filed Jun. 11, 2001.

BACKGROUND OF THE INVENTION

[0002] The present new and distinct variety originated from an open pollinated population of seedlings derived from the variety ‘Yumyeong’ (not patented) planted in 1990 at the HortResearch experimental orchard in Goddard Lane, Havelock North, New Zealand. A large group of open-pollinated seedlings on their own roots were placed under careful observation. One seedling representing the present variety was selected and asexually propagated for further evaluation. The selection was further propagated by asexual reproduction for the first time in 1995.

[0003] The new variety was budded onto ‘Golden Queen’ peach seedling rootstock and shows the unique combination of characteristics and distinctive colour are true to the original seedling tree and are transmitted through succeeding asexual generations.

[0004] The variety is characterised by late flowering, vigorous spreading growth; regular and heavy cropping of large, very firm,white-fleshed crisp-textured fruit which are clingstone with mild and sweet sub-acid flavor and fruit aroma. The fruit is further characterised by pink over-colour and very good handling qualities, and ripening 1 week before the parent ‘Yumyeong’.

SUMMARY OF THE INVENTION

[0005] The described variety of peach tree is of a medium to large size, vigorous, with a spreading growth habit. Trees of the variety bear regular and productive crops of medium to large white flesh, clingstone fruit with a sweet sub-acid taste and very firm crisp flesh. Fruit has very good flavour and eating quality. The firm flesh exhibits good storage qualities and the skin has red colour over a cream background. The fruit ripens mid season approximately 1 week before the ‘Yumyeong’ parent variety.

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] FIG. 2 shows external and internal views of the fruit. The photograph was taken after 2 weeks air storage of fruit harvested at eating maturity.

DETAILED DESCRIPTION OF THE NEW VARIETY

[0008] The following is a detailed description of the new variety with colour terminology in accordance with The Royal Horticultural Society Colour Chart (RHSCC) 2000 edition. The specimens described were grown in Havelock North and Clyde, Central Otago, New Zealand. The observations were made in the 2001 season on trees that were four years old at the time.

[0009] The present new variety of peach tree, the flowers, foliage and fruit herein described may vary slightly in detail due to climate, soil conditions and cultural practices under which the variety may be grown. Unless otherwise stated the present description is that of the variety grown under the environmental conditions prevailing near Havelock North, Hawke's Bay New Zealand.
