The exploitation of Croatian grapevine genetic resources for the breeding of new resistant cultivars 

Abstract

Croatian viticulture is mainly based on native grapevine varieties susceptible to various diseases and pests, which leads to unsustainable use of large amounts of pesticides. The sustainable development of viticulture in the future will only be possible by increasing the resistance of the grapevine through the development of new resistant varieties. Breeding programs have been launched in the leading wine-growing countries to develop resistant varieties possessing high-quality levels. Native cultivars from Croatia are not included in the breeding programs of other countries. In 2015 a breeding program was started at the University of Zagreb Faculty of Agriculture. The long-term goal is to develop new varieties suitable for Croatian growing conditions, with stable and durable resistance using native germplasm and other sources of resistance.  

 

Native varieties Grk and  Dišeća ranina were selected as a starting point for the breeding program because they pose female flower type, aiming to develop breeding lines with female flowers. The source of resistance in the program’s first stage is the Panonia variety. After applying molecular markers in the population of seedlings expressing the high level of phenotypic resistance to downy and powdery mildew, several plants were detected that inherited all three resistant gene loci (Rpv3, Rpv12 – downy mildew resistance, Ren3 – powdery mildew resistance) from Panonia and female flower from chosen native varieties. They were included as mother plants in the program’s next step and were crossed to obtain breeding lines with additional resistant gene loci.

Integrative study of Vitis biodiversity for next-generation breeding of grapevine rootstocks 

Drought is one of the main challenges for viticulture in the context of global change. The choice of rootstock could be leveraged for vineyard adaptation to drought as we can improve plant performance without modifying the scion variety. However, most of the existing rootstocks, selected over a century ago, have a narrow genetic background which could compromise their adaptive potential.

Optimization of the acquisition of NIR spectrum in grape must and wine 

The characterization of chemical compounds related with quality of grape must and wine is relevant for the viticulture and enology fields. Analytical methods used for these analyses require expensive instrumentation as well as a long sample preparation processes and the use of chemical solvents. On the other hand, near-infrared (NIR) spectroscopy technique is a simple, fast and non-destructive method for the detection of chemical composition showing a fingerprint of the sample. It has been reported the potential of NIR spectroscopy to measure some enological parameters such as alcohol content, pH, organic acids, glycerol, reducing sugars and phenolic compounds.

How are canned wine drinkers perceived? An investigation involving Swiss nationals and different scenarios of outdoor leisure activities

This study examines how people who consume wine in cans are perceived in terms of their basic personality characteristics, helps understand the role of cultural background on people’s perception, and verify the role played by the consumption context on the perception. Our hypothesis is that prejudice and negative attitudes towards wine in cans might exert a negative effect on the evaluation of people who consume canned wine. To evaluate this hypothesis, the consumption of wine in cans was evoked in four different contexts of use during outdoor leisure activity (beach resort, ski resort, desert safari, and party). In order to examine the effect of culture on subject’s response we use participants from Switzerland, a country where three different cultures, associated with three different languages, cohabit.

Combined use of leaf removal and natural shading to delay grape ripening in Manto negro (Vitis vinifera L.) under deficit irrigation 

The increasingly frequent heat waves during grape ripening pose challenges for premium wine grape production. This makes the development of irrigation and canopy management techniques of great importance to maximize yield and grape quality. A field experiment was carried out during 2021 and 2022 using Manto negro wine grapes to study the effect of two irrigation strategies and different light exposure levels on grape quality.

Reduction of the height of the canopy in fruit set and in pea size: vegetative, productive and maturation effects, in cv. Verdejo

Global warming is accelerating the technological ripening of the grape, with a loss of acidity, which requires that vineyard management can delay ripening to avoid it. The source-sink relation is essential for grape ripening, since it affects the distribution of photosynthates and substances derived from plant metabolism. A work is proposed to know the response of the vineyard to the drastic reduction of the foliar surface by trim down the shoots in cv.
