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.

Metabolomic profiling of heat-stressed grape berries 

The projected rise in mean air temperatures together with the frequency, intensity, and length of heat waves in many wine-growing regions worldwide will deeply impact grape berry development and quality. Several studies have been conducted and a large set of molecular data was produced to better understand the impact of high temperatures on grape berry development and metabolism[1]. According to these data, it is highly likely that the metabolomic dynamics could be strongly modulated by heat stress (HS).

High-throughput sequencing analysis based on nematode indices revealed healthier soils of organic vineyards 

Proper soil health assessments are crucial for sustainable cropland. Among the widely employed approaches, evaluating nematode community structure is particularly suitable. Traditionally, the taxonomic characterization of soil nematodes has relied on time-consuming morphology-based methods requiring experienced experts. However, molecular tools like high-throughput sequencing have emerged as efficient alternatives. In this study, we performed a metataxonomic analysis of soil samples collected from 57 vineyards in the DOCa Rioja region of Northern Spain, focusing on the impact of organic viticulture and cover cropping compared to integrated pest management (IPM) and tilling practices.

Volatile composition of Cabernet Sauvignon wines from Argentina, Portugal and Spain

Cabernet Sauvignon is one of the most cultivated grape varieties worldwide being grown in different environmental conditions due to its excellent adaptability. Volatile compounds deeply contribute to the sensory properties of wines therefore to wine quality. The aim of this work was to compare the aroma profile of Cabernet Sauvignon wines from different geographical areas and climatic conditions, namely from Argentina, Portugal and Spain, from the vintage 2022. In addition, the volatile composition of the Cabernet Sauvignon Portuguese wines from three vintages was evaluated.

Defoliation combined with exogenous ABA application results in slower ripening and improved anthocyanin profile

Reducing sugar accumulation in grape (Vitis vinifera L.) berries may be a way to mitigate the effect of climate change. Managing canopy and crop load is an effective way to do so, however, reducing canopy size has been demonstrated to induce undesirable effects on anthocyanins. The aim of this study was to test if an application of exogenous ABA on the grape berries of defoliated vines (⅔ of the leaves removed) can result in slower sugar accumulation while maintaining grape and wine quality. An experiment with defoliation and exogenous ABA application on directly on clusters (factorial design 2×2) was performed with ‘Tempranillo’ fruit-bearing cuttings.
