Abstract:
The clonal selection presents a very important mission for the
production and grape quality. It represents another more advanced step of
selection works, because it contributes to a radical improvement of existing
varieties. It comprises in choosing and multiplying the best vegetative
grapevine issue, from the most valuable grapevines. (Neagu M.I.).Many
varieties spread in culture are devoid of economic value, while others
degenerate along with growth in heterogeneous populations, making the
value of vineyard, established without taking measures to apply the selection
to decrease gradually.Increasing the biological potential of vinifera varieties
in culture and expansion of valuable grepevines can be made through clonal
selection. Through the work of clonal selection of the vinegrapes at INCDBH
Ştefăneşti it has been obtained a new selection of the Muscat d'Adda variety,
thus contributing to the improvement of grape varieties for mass
consumption. The clonal elite Mt. d'Adda Şt 22. was approved in 2009, being
qualitatively higher to the selected variety.In the work of clonal selection that
started at Ştefăneşti in 1996 it was used a new scheme that included 3 major
parts: mass positive selection and choosing of clonal elites from the mother
plantation followed by their rapid growth; Comparative study of elites in
terms of potential productivity, the quality of grapes, testing plant breeding
clones performing their ISTIS entry.
