Abstract:
The distinct trait comprised in the nowadays and future programes
concerning the genetic improving the grapes with the view to getting more
productive and qualitative varieties, ith higher resistance to the main
diseases and pests. They also take into consideration the genetic changed
varieties, having qualities able to respond to the more efficient intervention
of mechanization or to the new and simple culture technologies.
Because the Romanian viticulture comprises just a few varieties
destinated to the raisins production, it is desirable to extend in culture new
varieties of this group, where from, as many clones as possible will be then
selected.
In the experimental fields from INCDBH Ştefăneşti there was
conducted a comparative three years study on the main seedless varieties.
The attention of reserchers was especially got by the Canner variety, a
seedless one with medium ripeness.
In order to make a presentation of the main qualities of this variety, it
was compared to the Perlette one, which is more extended in the Romanian
vineyards.
The study was conducted on a period of three years and consisted in
ampelographical, agrobiological and technological determination of this
variety compared to Perlette.
