ABSTRACT:
SUMMARY OF THE INVENTION
‘Braeburn’ is an unpatented variety of apple commonly grown commercially in New Zealand, and increasingly in other part of the world. The fruit of ‘Braeburn’ is typically striped, with coverage of between 40% to 50% orange-red stripes. A number of sports or mutations have arisen on trees of ‘Braeburn’ which are similar in habit and yield to ‘Braeburn,’ but which have different skin coloration. One such sport is the variety ‘Hidala’ (U.S. Plant Pat. No. 7,526), which has skin color of orange-red stripes over about 50% to 70% of the fruit surface; another is ‘Mariri Red’ (U.S. Plant Pat. No. 11,604), which has approximately 100% coverage of red blush. Such sports with increased red coloration are seen to have some commercial advantage over ‘Braeburn’.
A limb mutation on a apple tree of variety Braeburn (an unpatented New Zealand cultivar) exhibited highly colored red striped and blushed fruit compared to its parental variety. The new variety has been asexually reproduced and named Joburn.
The mutation was noticed because 2 apples on a spur had higher red coloration than the rest of the crop on the tree.
The spur was left to grow for 2 seasons, and in August 1987 graftwood was taken and used to top-graft an existing tree on the owners property in Thompson Rd, Hastings. In Spring 1988 budwood was taken from the top-grafted tree to produce 200 second generation trees on M793 rootstock. These trees were planted in winter 1990.
Asexual propagation by budding and grafting in Hawkes Bay, New Zealand, has shown that the unique combination of plant characteristics and distinctive coloration characteristics come true to form and are established and faithfully transmitted through succeeding generations.
