CONCLUSIONS
With regard to the variability of the
characteristic length of shoots, the Ribes
nigrum varieties Abanos and Elita 124 had the
maximum length of 84.5 cm or 82.00 cm.
Ribes rubrum varieties Elite and Detwar had
increases of up to 59.00 cm and 41.80 cm. Both
species had a high variability of the length of
shoots, which reflects the importance of the
environment conditions on this phenotypic
characteristic as well as for the biological
diversity of the varieties taken into study.
The highest weight of the bunches was
determined for the Ribes nigrum varieties Deea
and Roxia, with 15.87 g and 13.14 g/bunch
respectively, and for the Ribes rubrum species,
emphasizing Rolan and Jonkheer van Tets
varieties.
The S% variability coefficient for the weight of
bunches showed values between 47.4 and
52.87, for Ribes nigrum, and for Ribes rubrum
even higher, up to 70.3.
The calculated production per varieties showed
that the highly productive variety of
blackcurrant is Deea, with a production of
1614.16 t bunches/ha, followed by the
redcurrant variety Rolan, with a production of
940 t bunches/ha.
