Abstract
A new and distinct kiwi plant of the species Actinidia chinensis is described. The cultivar results from a controlled pollination using a male A. chinensis selection ‘RY,’ and a female A. chinensis selection ‘A124.’ Both named parents (‘RY’ and ‘A124’) are unpatented cultivars. The new cultivar is distinguished by its medium fruit size, obovoid fruit shape, greenish-yellow fruit coloring, and its medium to early harvest date in early April.
Description
Genus and species of plant claimed: Actinidia chinensis.
The present application claims priority from New Zealand Plant Variety Rights Application No. KIW026, entitled ‘SKELTON A19’ filed Dec. 22, 2006, with the Commissioner of Plant Variety Rights in New Zealand, which is herein incorporated by reference.
Kiwi plants in cultivation are mainly varieties of A. deliciosa, particularly ‘Hayward’ although some A. chinensis and A. arguta varieties are grown. A. deliciosa and A. chinensis are closely related and varieties of both types have large fruit (about 100 g) with hair on the skin. The main varieties in New Zealand are ‘Hayward’ (A. deliciosa) and ‘HORT16A’ (A. chinensis). Fruit are usually cut and eaten with a spoon.
All Actinidia species are dioecious, so female varieties have to be interplanted with male pollinizers to ensure fruit production.
A. chinensis vines are deciduous and tend to grow vigorously in spring and summer when rapidly-growing shoots can intertwine and tangle if not managed. Vines do best in a mild warm-temperate climate without late spring or early autumn frosts. They produce consistently heavy crops when grown in well-drained fertile soils and given regular irrigation in dry spells.
A. chinensis flowers in late September to late October in New Zealand. Harvest of A. chinensis fruit occurs from late February to late June in New Zealand depending on the selection and location of plantings.
The present invention is a new and distinctive kiwifruit variety having a medium sized obovoid fruit shape, a fruit flowering date of early October, with a fruit harvest date of early April. This new variety is designated ‘Skelton A19’ and is derived from a controlled pollination using a female A. chinensis selection ‘A124’ and a male A. chinensis selection RY of unknown parentage.
Neither of the parents are registered with the Plant Variety Rights Office in New Zealand or patented. The parent plants are part of an ongoing breeding program established in New Zealand in 1975.
This new variety was created during the course of a planned plant-breeding program, which was initiated in Waiuku, New Zealand in 1994 and approximately 300 seedlings were raised at Rangiriri, New Zealand. ‘Skelton A19’ first flowered in October 1998 and fruit were assessed in April 1999. Following fruit assessment, ‘Skelton A19’ was grafted onto ten Actinidia deliciosa seedling rootstocks and onto ten Actinidia chinensis seedling rootstocks. The unique characteristics of ‘Skelton A19’ continued and the asexually reproduced plants were true to type.
The new variety can be asexually reproduced as cuttings or by grafting or budding on to seedling or cutting-grown rootstocks of A. deliciosa or A. chinensis, or by striking cuttings, or by tissue culture. Trial plantings of grafted plants established in Rangiriri, New Zealand in 1999 have shown that the unique combination of characteristics come true to form, are established, and transmitted through succeeding asexual propagations.
The distinctive characteristics of ‘Skelton A19’ were first observed with the first fruit maturing in April 1999. The distinctive characteristics of this new Kiwi variety, described in detail below and shown in the accompanying photographs, were observed in April 2006 at Rangiriri, New Zealand. The age of the plants was approximately seven years from grafting onto seedling rootstocks.
Comparison with the similar variety ‘HORT16A’ (U.S. Plant Pat. No. 11,066) shows that ‘Skelton A19’ may be distinguished as follows in Table 1:

The most striking difference between ‘Skelton A19’ and ‘HORT16A’ is that of fruit shape, flowering and harvest times. ‘Skelton A19’ obovoid fruit have slightly blunt protruding stylar end, whereas ‘HORT16A’ are ovoid with a strongly protruding blunt stylar end. In addition the flowering and harvest dates of ‘Skelton A19’ are approximately two weeks prior to that of ‘HORT16A’ in early October and early April, respectively.
