AbstractGenetic improvement by crossbreeding of table grape varieties was realized at the Istituto Sperimentale per la Viticoltura for the achievement of the following main targets: early species, seedless species, species with high content of fructose in grapes and, at the same time, a research concerning the hereditary transmission of these features.
The results are the followings:
- Registration in the National Catalogue of the varieties of 4 new table grape varieties that are interesting for their ripening (IC. 199, LC. 218, IC. 120, IC. 213).
- Information concerning the heritability of earliness, average weight of grape and bunch for the varieties examined.
- Achievement of varieties that have a ratio between the two monosaccharides considerably tending towards fructose. This feature remains constant throughout the years.
