Evaluation of blackberry varieties and raspberry-blackberry hybrids in conditions of the Bryansk region

Abstract

The results of studying of 10 blackberry varieties and 5 raspberry-blackberry hybrids on the main economic and biological indices in the conditions of the Bryansk region were presented. Low winter hardiness of stems of studied genotypes (from 0.5 to 2.3 points) and quite good regeneration ability of some varieties (Black Satin, Gazda, Thornfree, Orcan, Marion, Smootstem, Loganberry Thornless) have been set up. Analysis of components of productivity has been made. The largest fruits (with average weight of berries 4.0-6.2 g) form the varieties Thornfree, Loch Ness, Marion, Smootstem, Black Satin, Loch Tay. The blackberry varieties Thornfree, Black Satin and Smootstem have been distinguished as the best according to the complex economic and biological characteristics. They can be grown as in amateur gardening and on an industrial basis. The variety Loch Tay and raspberry-blackberry hybrids Mario, that differ by large-sized and high taste fruit have been recommended for subsistence farming.
