ABSTRACT:

Latin name of the genus and species of the plant claimed: The variety is botanically identified as Rubus L. Subgenus Rubus.
1. BACKGROUND OF THE INVENTION
This invention relates to a new cultivar of blackberry called ‘Driscoll Carmel’. The new cultivar was developed from hybridization of the unpatented female cultivar ‘BY45.1’ with the unpatented male selection ‘BY63.2’. The parents were crossed in 1996, where after fruit and seed were collected to produce seedlings for field planting in Watsonville, Calif. in 1997. The new cultivar was selected in 1998 for its good flavor, fruit firmness and season of ripening. The cultivar has been asexually propagated in Watsonville, Calif., 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 ‘Driscoll Carmel’. The variety is botanically identified as Rubus L. subgenus Rubus. The variety is a complex Rubus hybrid, which can be characterized as an erect tetraploid with considerable
R. allegheniensis
background with other species such as
R. trivialis, R. argutus R. procerus,
and
R. ulmifolious
also appearing in its background. The new cultivar produces a floricane crop which begins in late 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 low chill requirement, and its improved quality and shipping characteristics. Yield of the new cultivar is high when compared to many other varieties.
3. COMPARISON TO SIMILAR VARIETIES
The variety that we believe to be similar to ‘Driscoll Carmel’ from those known to us is ‘Olallie’, an unpatented variety. ‘Driscoll Carmel’ is particularly different from ‘Olallie’ by being later ripening, having less postharvest color reversion, having less acidic flavor, and having better fruit firmness. Further detailed comparison of ‘Driscoll Carmel’ to ‘Olallie’ and ‘Chester’ is presented in Table 1.
