Abstract
During the three-year tested period (2016-2018), the most important ampelographic and productive properties of the newly bred table grape cultivar ‘Kristina’, which originated from the cross combination ‘Muscat Hamburg’ × ‘Seedling 108’, were studied.
The cultivar was created at the Faculty of Agriculture, University of Belgrade.
It was compared with the standard cultivar ‘Muscat Hamburg’ in terms of the studied properties.
Regarding the ampelographic properties, the ‘Kristina’ cultivar represents a unique genotype and has a fully open tip of the young shoot, five lobes in the mature leaf, a hermaphrodite flower type, a lax bunch, a narrow ellipsoid berry shape, a blue-black color of the berry skin and a muscat flavor.
Statistically significant differences in production traits between the ‘Kristina’ cultivar and the standard cultivar were found for ripening time, yield, bunch length, bunch width and TSS (total soluble solids). On average, the ‘Kristina’ cultivar had a later ripening time (September 26) than the standard cultivar (September 18). The ‘Kristina’ cultivar had a yield of 2.19 kg m-2, a bunch weight of 328.0 g and a berry weight of 3.08 g, while the ‘Muscat Hamburg’ cultivar had a yield of 1.78 kg m-2, a bunch weight of 312.5 g and a berry weight of 3.61 g.
The TSS and TA (Total Acids) in the must of the ‘Kristina’ cultivar was 22.82%, i.e. 7.1 g L-1 respectively, while that of the ‘Muscat Hamburg’ cultivar was 17.2%, i.e. 6.3 g L-1 respectively.
The ‘Kristina’ cultivar showed a very high resistance to the most important fungal diseases (Plasmopara viticola, Uncinula necator, Botrytis cinerea). Due to a number of positive properties, especially the beautiful and attractive appearance of bunches and berries, as well as disease resistance, ‘Kristina’ cultivar is expected to spread in production vineyards in Serbia.
