DNA based molecular markers allow precise, objective and rapid cultivar identification. In this study, five ISSR and two sets of fluorescence-labeled TP-M13-SSR markers were applied for discrimination of eight closely related wheat cultivars. Five ISSR primers revealed a total of 43 distinct reproducible bands, 29 (67.44%) of the 43 bands were polymorphic. The number of polymorphic bands detect...

Argentinean Vitis vinifera cultivars although originated from Europe, have clear ampelographic and genotypic differences as compared with the European cultivars currently used in wine making. In vitro evaluation of salt tolerance has been used in many species. Our hypothesis was that Argentinean cultivars are more tolerant to salinity than European ones. Three European cultivars, Malbec, Cabern...

The accurate identification of orchardgrass (Dactylis glomerata L.) cultivars is necessary to ensure purity for consumers, the effective utilization of cultivars, and to protect the intellectual property for breeders. Therefore, this study aimed to use SSR to construct DNA fingerprinting of orchardgrass cultivars. The genetic diversity of 32 orchardgrass cultivars originated from 21 countries, ...

Several abiotic and biotic stresses can affect soybean in a growing season. Heterodera glycines, soybean cyst nematode, reduces yield of soybean more than any other pathogen in the United States. Field and greenhouse studies were conducted to determine whether preemergence and postemergence herbicides modified the reproduction of H. glycines, and to determine the effects of possible interactive...

Panax ginseng has been cultivated for centuries, and nine commercial cultivars have been registered in Korea. However, these nine elite cultivars are grown in less than 10% of ginseng fields, and there is no clear authentication system for each cultivar even though their values are higher than those of local landraces. Here, we have developed 19 microsatellite markers using expressed gene seque...

There is renewed interest in ethanol production, and sugarcane promises to be a sustainable ethanol source. Few studies have been done on the effect of season on biomass production, and no studies have quantified yields of a range of cultivars in terms of intercepted radiation. The objective of this study was therefore to assess how season affects the biomass yields of a number of commercial cu...

Guo D.-L., Zhang Q., Zhang G.-H. (2013): Characterization of grape cultivars from China using microsatellite markers. Czech J. Genet. Plant Breed., 49: 164–170. A total of 32 different grape cultivars including representatives of local Chinese cultivars, some important and widely grown Chinese cultivars and international reference cultivars were genotyped at nine microsatellite loci in order to...

Codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae) is a major fruit feeding pest of apples. Understanding susceptibility differences of various apple cultivars to CM oviposition is an important step in developing resistant varieties as well as monitoring and management strategies for this pest in apple orchards planted with mixed-cultivars. In this context, oviposition preferenc...

Three field trials were conducted to determine response of Meloidogyne javanica to tomato cultivars containing the Mi gene for resistance in sequential tests. Trials were conducted in spring and fall 1997 and spring 1998 on the same site. Tomatoes were grown on polyethylene mulch at a site initially treated with methyl bromide and then infested with M. javanica via drip tubing. Cultivars with t...

Studies were conducted at the horticulture unit of Sokoine University of Agriculture, Morogoro, Tanzania, to assess the incidence and effect of mango weevil, Cryptorhynchus mangiferae (F.) (Coleoptera: Curculionidae), infestation on mango, Mangifera indica L., seed viability. Three polyembryo mango cultivars ('Sindano nyeusi', 'Sindano nyeupe', and 'Dodo') as well as three monoembryo mango cult...
