Due to the pro-health properties of highbush blueberry fruit, the interest in cultivation of this species has been growing significantly, which is evidenced by the current increase in world fruit production. Therefore, the aim of our review study is to present the impact of soil and climatic conditions and cultivation methods of Vaccinium corymbosum L. on fruit yield and quality in Central and Eastern Europe. In this region, one of the most important abiotic factors determining the yield level is the minimum temperature of the winter period and short-term increases in temperature, which are conducive to the damage to flower buds. Another factor determining the success of cultivation is soil. In addition, highbush blueberry has specific soil requirements, which result from its characteristic root structure. The adverse impact of soil factors can be mitigated to a certain extent by the use of mycorrhizal fungi. In this chapter, besides the cultivation conditions of V. corymbosum, the pro-health properties of fruits resulting from the presence of bioactive compounds such as polyphenolic compounds, flavonoids, especially anthocyanins, will be presented. Besides, factors, such as environmental conditions, degree of ripeness and variety, affect the content of bioactive substances.

Among the berries, strawberries are the most commercially produced and consumed and their production and consumption are increasing in the world due to their enthusiastic aroma, taste, and biochemical properties. Strawberry is belonging to the genus Fragaria, from the family Rosaceae. It is indicated that the homeland of the strawberry is South America (Chile). It is well-known that people living in Asia, Europe, and America commonly use the wild F. vesca. In other regions such as Japan, North China and Manchuria, Europe-Siberia, and America there are different ecogeographic zones where alternative species are clustered. Despite its origins in the Pacific Northwest region of North America, F. ananassa is now grown all over the world. Strawberry is one of the most widespread berry species grown in almost every country including high altitudes of tropical regions, and subtropical and temperate areas. In this chapter, we aimed to offer new perspectives on the future of strawberry cultivation techniques by analyzing recent academic studies on strawberry production.

The cultivated strawberry (Fragaria x ananassa) is derived from Fragaria chiloensis and Fragaria virginiana species a few centuries ago, and it is one of the most preferred and consumed berries all over the world because of its a good source in terms of many nutritional elements. Strawberry has high genetic variability and adaptation to different environmental conditions due to its highly heterozygous nature. In the last decades, many farmers, breeders, researchers even consumers have started to focus on berry quality traits such as large fruit, uniform shape, high fruit firmness, high fruit sensorial quality (aroma contents), color, gloss, and resistance to pathogens. Thus, the development of novel strawberry cultivars or genotypes with high nutritionally quality traits has become one of the main aims in strawberry breeding programs. Biotechnological tools such as the identification of quantitative trait loci (QTL) and marker-assisted selection (MAS) are the most widely used technologies in fruit breeding programs for shortening the breeding period. Identification of QTLs in agnomical important traits are very valuable tools for early selection in strawberry breeding programs. This chapter is focused on QTL and marker assisted breeding studies in strawberry to date and provides new perspectives on molecular breeding in strawberry breeding.

Global climate change and possible drought scenarios have forced researchers, breeders and producers to create new plant patterns that will adapt to changing climate and soil conditions for production of horticultural plants in the future. Here, the most important topic is the shortening of the physiological growth period of plants due to abiotic stress. In other words, reductions experienced in both cooling needs and maturation periods cause negative impacts on flowering times and amounts, and this causes significant loss of yield. In recent years, the production of berry fruits that will adapt to drought conditions has attracted the attention of breeders and producers. The aim of this study is to discuss in detail the possibilities of producing berry fruits that are resistant to drought and negative climate conditions and to present research results and recommendations about this topic. In this study, the production opportunities in arid and negative climate conditions for the berry fruits of strawberry (Fragaria vesca L.), mulberry (Morus spp.), fig (Ficus carica L.), blackberry (Rubus fruticosus L.), chokeberry (Aronia melanocarpa L.), rosehip (Rosa canina L.), raspberry (Rubus idaeus L.) and blueberry (Vaccinium corymbosum L.) were researched and recommendations are made about production methods for some varieties and types resistant to drought in berry fruit cultivation.
