ABSTRACT:

1. BACKGROUND OF THE INVENTION
This invention relates to a new cultivar of blackberry called ‘Driscoll Cowles’. The new cultivar was developed from hybridization of the female cultivar ‘Sonoma’ (U.S. patent application Ser. No. 09/772,330) with the unpatented male variety ‘Loch Ness’. The parents were crossed in 1993 where after fruit and seed were collected to produce seedlings for field planting in Watsonville, Calif. in 1994. The new cultivar was selected in 1995 for its good flavor, large fruit size, fruit firmness and thornless canes. The cultivar has been asexually propagated in Watsonville, Calif. and reproduced true to type plants by in vitro shoot tip culture.
1.1 Latin name of the genus and species of the plant claimed: The variety is botanically identified as
Rubus L.
subgenus
Rubus.
2. SUMMARY OF THE INVENTION
The present invention provides a new and distinct blackberry cultivar named ‘Driscoll Cowles’. 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 mid-July and continues until late September. 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 mid-late season of fruit ripening, its large fruit size and its improved flavor.
3. COMPARISON TO SIMILAR VARIETIES
The variety that we believe to be similar to ‘Driscoll Cowles’ from those known to us is ‘Chester’, an unpatented variety. ‘Driscoll Cowles’ is particularly different from ‘Olallie’ by being slightly earlier ripening, having larger fruit size and having less acidic flavor. Further detailed comparison of ‘Driscoll Cowles’ to ‘Olallie’ and ‘Chester’ is presented in Table1.
