Prunus avium species of the Rosaceae family exhibit gametophytic self-incompatibility. Determination of the self-incompatibility genotype of individuals is essential for genetic studies and the development of informed management strategies. The PCR-based detection of S-allele helps to promote and speed up traditional breeding activity and hence molecular analysis of the perspective genotypes has become more intensive in all cherry growing countries. The alleles S3, S4 and S9 from 34 accessions of Czech collections were determined using the polymerase chain reaction (PCR)...
Seed genotypes for harvesting seeds in the production of generative rootstocks for peach cultivarsOriginal Paper

Six novel peach genotypes, designated BN-1, BN-3, BN-4, BN-7, BN-8 and BN-45, were assessed for usefulness as sources of seeds for production of generative rootstocks for peach cultivars. The genotypes BN-8 and BN-1 were the most intensely flowering, while the most abundantly and regularly fruiting genotype was BN-8, which also produced the smallest stones. The smallest fruits and the highest seed yields were produced by the genotypes BN-8 and BN-7. All of the genotypes under assessment produced seeds with higher germination capacities compared with the two control cultivars, Mand¿urska and Siberian C, with the seeds of the genotypes BN-8, BN-4 and...
New strawberry genotypes tested for organic production on a Verticillium-infested siteOriginal Paper

Nineteen new strawberry breeding clones, bred at the Institute for Breeding Research on Fruit Crops in Dresden-Pillnitz, Germany, were evaluated for their suitability for organic production at a Verticillium-infested site in Vienna, Austria. Soil cover, plant vitality, resistance to leaf spot diseases as well as flower damages by the strawberry blossom weevil (Anthonomus rubi) and by spring frost were recorded. In two consecutive years, marketable yield and fruits infested by Botrytis cinerea were assessed. Three breeding clones, P-7189, P-8043 and P-8071, were considered as suitable for organic strawberry production. P-7189...
Fingerprinting of Vaccinium corymbosum cultivars using DNA of fruitsOriginal Paper

In recent years the production and consumption Vaccinium corymbosum has increased. Highbush blueberry cultivars are divided into three types, northern, intermediate and southern. The traditional methods for classification of highbush blueberry cultivars using morphological and flavour traits are largely unsuccessful, due to environmental influences. The genetic similarity of ten highbush blueberry cultivars was evaluated using random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) markers from fruits and leaves. The DNA concentrations obtained in fruits and leaves were very similar and the band profiles observed in...
Alternate partial root-zone drying irrigation improves fruit quality in tomatoesOriginal Paper

Alternate partial root-zone drying (PRD) irrigation and deficit irrigation (DI) are water-saving irrigation strategies. Here, comparative effects of PRD and DI on fruit quality of tomato (Solanum lycopersicum L.) were investigated. The results showed that the irrigation treatments had no effect on tomato yield but significantly affected several organic and mineral quality attributes of the fruits. Compared to DI, PRD significantly increased the fruit concentrations of Ca and Mg, and fruit juice concentrations of total soluble solid, glucose, fructose, citric and malic acid, P, K and Mg. It is concluded that PRD is better than DI in terms of...
Evaluation of some pepper genotypes as rootstocks in water stress conditionsOriginal Paper

Water stress is a major environmental factor that limits crop production and it is important to develop crop varieties with higher yield under water scarcity. Increased pepper tolerance to water stress through grafting onto robust rootstocks could be an optimal alternative in the context of environmentally friendly agriculture. Our work evaluated the behaviour of 18 pepper genotypes during vegetative and reproductive stages under water stress in order to select tolerant genotypes to be used as rootstocks for pepper cultivation. The pepper tolerance screening was based on photosynthetic parameters. The genotypes Atlante, C-40, Serrano, PI-152225, ECU-973,...
