Productivity of Rubus idaeus L. x Rubus subg. Eubatus Focke

Rubus idaeus L. x Rubus subg. Eubatus Focke

The productivity of raspberry-blackberry hybrids is determined by a complex of morphological indicators, including berry weight, the number of laterals per stem, and the number of ovaries, and strongly depends on stem survival during the winter period.

In the reference 3 varieties crop Rubus idaeus L. x Rubus subg. Eubatus Focke, where this is mentioned in the description.

To evaluate the productivity of Rubus idaeus L. x Rubus subg. Eubatus Focke hybrids, yield indicators in kg per bush or t/ha are used, as well as an analysis of components: average berry weight, number of flowers and ovaries per shoot, number of fruiting laterals, and the number of berries on each of them.

In the central fruit-growing zone, the productivity indicators of the hybrids vary significantly, amounting, for example, to about 0.6 kg per bush for the Tayberry cultivar. The yield potential is closely related to the stem development biology inherited from the blackberry; therefore, shoot thinning and winter covering in regions with cold climates are critical for its realization.

In breeding programs, the productivity of hybrid forms is evaluated relative to control cultivars, while the correlations between lateral length and the number of berries on them are considered key predictors of the final yield.
