ABSTRACT:
LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED
Rubus hybrid
VARIETY DENOMINATION
‘Sleeping Beauty’
1. BACKGROUND OF THE INVENTION
This invention relates to a new cultivar of blackberry called ‘Sleeping Beauty’. The new cultivar was developed from hybridization of the unpatented female cultivar ‘Brazos’ with the unpatented male cultivar ‘Hull Thornless’. The parents were crossed in Spring 1991 whereafter fruit and seed were collected to produce seedlings for field planting in Watsonville, Calif. in 1992. The new cultivar was selected in 1994 for its early fruiting period and large fruit size. The cultivar has been asexually propagated, and reproduced true to type plants by in vitro shoot tip culture.
2. SUMMARY OF THE INVENTION
The present invention provides a new and distinct blackberry cultivar named ‘Sleeping Beauty’. The variety is botanically identified as Rubus L. subgenus Rubus. The variety is described as a complex Rubus hybrid. It can be characterized as an erect tetraploid with considerable
R. allegheniensis
background with other species such as
R. trivalis, R. argutus, R. ulmifolius,
and
R. procerus
also appearing in its background. The new cultivar produces a floricane crop which begins in mid-May and continues until mid-August. The new blackberry variety is distinguished from other varieties by a number of characteristics as set forth in Table 1. In particular, the new cultivar is distinguished by its large fruit, low chill requirement and long fruiting period. Yield of the new cultivar is moderate to high when compared to many other varieties. There have been no observed plant or fruit diseases and no observed pest resistance or susceptibility. The variety has been developed for fresh market shipping use, and has performed well in coast-to-coast shipping tests and held up well after cold storage at 34 degrees Fahrenheit for periods of up to ten days.
3. COMPARISON TO SIMILAR VARIETIES
The variety that we believe to be similar to ‘Sleeping Beauty’ from those known to us is ‘Brazos’, an unpatented variety. ‘Sleeping Beauty’ is particularly different from ‘Brazos’ by having firmer, less acidic fruit and by being slightly smaller in size.
