ABSTRACT

This paper aims to highlight the superior agrobiologic potential and technologically of 21 hybrid elites, obtained by the hybridization of the varieties Muscat Iantarnîi x Canner (codified HI), Victoria x Black Pearl (codified BP) and Victoria x Victoria (codified A) and compared with the genitors.
Since the hybrid elites selected from the experimental fields, have been highlighted by several descriptors, have been established correlations between all studied agro biological and technological elements: viability of the buds, total and fertile shoots, coefficient of absolute and relative fertility, The indices of absolute and relative productivity, the weight of the bunch and berry, content of the must in sugars and acidity.[1] The graphical representation of relations between quantitative and qualitative characteristics of hybrid descendants appealing to function regression and the correlation coefficient has highlighted the connections and meaning of the variables.
This paper aims to highlight the superior agrobiologic potential and technologically of 21 hybrid elites, obtained by the hybridization of the varieties Muscat Iantarnîi x Canner (codified HI), Victoria x Black Pearl (codified BP) and Victoria x Victoria (codified A) and compared with the genitors. Because the selected hybrid elites in experimental fields, descendants of three types of hybridization, were highlighted by several descriptors, have been established the correlations between all studied agro biological and technological elements.

Keywords: agrobiological and technological descriptors, hybrid elites, regression coefficients
