VARIETIES RECENTLY IMPORTED BY BLUEBERRIES NEW ZEALAND

BOUNTY

Type: Northern Highbush

Season: Mid Season

General Description: A mid-season, low chill (600-700 hours) northern highbush breed in North Carolina State University by Ballington, Mainland, Duke, Draper and Galletta. Berries are very large and have good flavour with the colour, stem scar, and firmness all being above average.

Needs intensive management to perform at its best, but returns are said to justify the effort for growers aiming at a hand-picked, premium berry market. With good practice the bush is consistently productive, displays field tolerance to cane canker and stem blight but is susceptible to anthracnose. Berries hang well on the plant and have good shelf life.

District Suitability: Not fully tested in New Zealand but will probably perform best at northern sites. Should flower in time with late flowering southerns and main crop northerns.

Limitations: This variety is only available for Blueberries New Zealand Members.

JUBILEE

Type: Southern Highbush

Season: Late Season

General Description: A late season, low chill (500 hours) southern highbush breed in Mississippi by Gupton, Spiers and Draper. Berries are medium, have a small scar with good colour, flavour and firmness. Flowers later that the earliest rabbiteyes but ripens two weeks earlier where it is grown in the USA. Requires good cross pollination to perform. The bush is upright, vigourous and productive.

District Suitability: Not Fully tested in New Zealand but being a southern highbush will perform best in northern sites with milder winters. Should flower and fruit with Magnolia, Brigitta and Lateblue.

Limitations: This variety is only available for Blueberries New Zealand Members.

MAGNOLIA

Type: Southern Highbush

Season: Late Season

General Description: Low chill (500 hours), late flowering southern high bush breed by Paul Lyrene out of the University of Florida. Flowers and ripens with Jubilee. Berries are medium, with a small scar and good colour, flavour and firmness. The bush has a spreading habit, is vigorous, productive and is of medium height. The plant needs good cross pollination to perform at its best.

District Suitability: Like Jubilee, would suit areas with milder winters. Should flower and fruit with Jubilee, Brigitta and Lateblue.

Limitations: This variety is only available for Blueberries New Zealand Members.

SIERRA

Type: Northern Highbush with Rabbiteye ancestry

Season: Mid-season

General Description: High chill (1000+ hours) pentaploid breed by Draper and Jelenkovic from the University of North Carolina. Treated as a northern highbush but it has rabbiteye in its ancestry. Its genetics means it is largely infertile and will produce almost entirely seedless berries (<1 seed per berry). Medium to large berries with good firmness, scar and colour. Can make a very high quality berry and the firmness suits machine harvesting. The bush is vigourous, productive and upright.

District Suitability: Sierra will suit areas that have over 1000 hours chill, preferably 1200+. Should flower and fruit with Nui and other main crop highbush.

Limitations: This variety is only available for Blueberries New Zealand Members.

LEGACY

Type: Southern Highbush

Season: Late season

General Description: Higher chill (600-700 hours) southern highbush breed by Draper out of North Carolina State University. Medium sized berries with good firmness, excellent scar and superior flavour. The bush is vigorous, upright and can have a high yield. Has been a consistent performer in the US and it is considered one of the best commercial southern highbush cultivars. Pickers are known to refer to it as the ‘Gold Bush’ due to its heavy production. Can be machine harvested.

District Suitability: Not fully tested in New Zealand but should suit the central North Island southwards. Adapts well to most soils and cold to moderate climates. Should flower with Brigitta.

Limitations: This variety is only available for Blueberries New Zealand Members.

OLYMPIA

Type: Northern Highbush

Season: Mid-season

General Description: Mid-chill (700-800 hours) northern highbush breed by a grower, Joseph Eberhardt and originally released in 1933. The berries are medium to large, have average colour and scar with resistance to dropping and cracking. Consistently rated by growers and customers as the best tasting blueberry.

The bush is spreading, vigorous and a moderate producer. Doesn’t perform well in frost prone sites and hard pruning is needed to force upright growth. If trained appropriately it is suited for machine harvesting and frozen packs (high brix, uniform size) as well as fresh market.

District Suitability: Not fully tested in New Zealand but should perform in all but the most northern blueberry growing areas. Should flower with Nui and other maincrop highbush.

Limitations: This variety is only available for Blueberries New Zealand Members.

SPARTAN

Type: Northern Highbush

Season: Early-mid season

General Description: High chill (1000+ hours) northern highbush breed by Darrow and Elliot out of Maryland. Berries are large, attractive with firm flesh and very good flavour. One of the most attractive, easy to pick blueberry plants. The bush is upright, has moderate vigour, is hardy and its structure suits mechanical harvesting. The plant blooms late but fruits early, and is frost resistant. Requires a light, well-drained soil but once established at a favourable site it will perform very well.

District Suitability: Will need 1000+ hours chill and appropriate soil to perform, but should do well in southern sites that require a hardier plant. Should flower and fruit with Duke.

Limitations: This variety is only available for Blueberries New Zealand Members.
