The study regarding the agrobiological and technological characteristics of some hybrid elites for table grapes obtained at N.R.D.I.B.H. Stefanesti
Journal Title: Romanian Journal of Horticulture - Year 2021, Vol 2, Issue 2
Abstract
This paper aims to highlight the superior agrobiological and technological potential of hybrid genotypes, obtained by intraspecific hybridization of cultivars 'Victoria' x 'Black Pearl', 'Muscat de Poloskei' x 'Victoria', 'Coarnă neagră' x 'Victoria', 'Victoria' x 'Victoria'. Several genotypes resulted from the hybridization of the mentioned cultivars, which stood out through at least two characters, similar or superior to the parental cultivar were selected in the comparative field. The evaluation of agro-biological characteristics of elites was based on the following indices: percentage of fertile shoots, fertility, and productivity coefficients. Technological descriptors related to the weight of the bunches, the weight of 100 berries, the skin's weight, the seeds, the content of the wort in sugars, the content of the wort in acidity were used in the study. The Victoria cultivar was taken as a witness, being considered a reference both nationally and internationally. The selected genotypes were distinguished by large grapes, very large grains, pleasant colors, high tolerance to biotic and abiotic factors. The new perspective elites show a high percentage of buds, high fertility, medium to high, the accumulation of sugars and total acidity in the must in a favorable way for mass consumption. To present more conclusively the multitude of data obtained, through statistical-mathematical processing, the general conclusions related to the mode of manifestation of hybrid elites in interaction with biotic and abiotic factors have been formulated considering the natural variability of all processes and phenomena involved.
