The random amplified polymorphic DNA (RAPD) technique and microsatellites were used to study the genetic diversity and to identify cultivars within a collection of 95 cultivars of Prunus armeniaca L. A dendrogram based on 13 RAPD primers and a dendrogram based on 9 microsatellite primers were prepared using the unweighted pair group method with average (UPGMA) group analysis. In both dendrograms, the cultivars were classified into five groups, according to their geographic origin: hybrids originated by hybridization among cultivars of European and Asian origin, European cultivars, American cultivars, Asian cultivars and interspecific hybrids....

Quince (Cydonia oblonga Mill.) is a minor fruit crop, which is primarily used for marmalade, jam, sauce and as rootstocks for pears. Different cultivated and local quince genotypes are grown in almost all parts of Turkey for fruit usage. In this study, randomly amplified polymorphic DNA (RAPD) technology was used to study the genetic relationships among 13 quince accessions selected from different parts of Turkey. Thirty decamer primers were used and 14 of them did not produce any polymorphism. The remaining 16 primers ranged in their amplification fragments between one (P-402, P-437, OPA 10, OPA 16, OPA 18 and OPA-19) and five (OPA-06 and...

The aim of the study was to find effects of tomato grafting on another cultivar. The tomato cultivars used as scions were Yeni Talya, Swanson and Beril. Cultivars used as rootstocks were Beaufort and Arnold. Cleft grafting methods were applied. The following characteristics of grafted and nongrafted plants were recorded: fruit index, number of fruits/truss, fruit weight, fruit yield, dry matter, pH, concentration of soluble solids, titratable acidity, total sugar and lycopene and vitamin C. The results showed that fruit yield and fruit index, number of fruits/truss and fruit weights were improved by grafting. Fruit quality, measured in terms of dry...
Biotechnological methods utilized in Cucumis research - A review

Hort. Sci. (Prague), 2011, 38(4):150-158 | DOI: 10.17221/143/2010-HORTSCI
Our biotechnological research on selected Cucumis species has encompassed interspecific hybridization via embryo-rescue, in vitro pollination, somatic hybridization and cytogenetics of protoplasts. Embryo-rescue and in vitro pollination are suitable in vitro techniques for production of hybrid embryos. These methods were tested and optimized for cucurbits. Protoplast culture is another valuable tool for biotechnological applications, such as somatic hybridization and genetic transformation. We study protoplast dedifferentiation not only as a biotechnological application in breeding systems, but mainly to describe...
Micropropagation of cranberry (Vaccinium macrocarpon) through shoot tip cultures: Short communication
J. Sedlák, F. Paprštein
Hort. Sci. (Prague), 2011, 38(4):159-162 | DOI: 10.17221/115/2010-HORTSCI
The goal of this study was to determine an efficient micropropagation system for cranberry (Vaccinium macrocarpon Ait.). Cranberry cultivar Howes was successfully established in vitro using mercuric chloride in a concentration of 0.15% as a sterilization solution. Anderson's rhododendron medium (AN), half-strength Murashige and Skoog medium (half-MS) and McCown woody plant medium (WPM) containing the cytokinin zeatin in concentrations 0.5, 1 or 2 mg/l were tested. Generally, the highest multiplication rate (2.7) was obtained for cv. Howes on AN medium with the concentration 1 mg/l of zeatin. The effects of indole-3-butyric acid (IBA),...
