The genus Allium (Family: Alliaceae) is the most important among the bulbous vegetable crops. characterization of Alliums based on phenotypic traits is influenced by the environment and leads to biased diversity estimates. Recognizing the potential of DNA markers in plant breeding, researchers have adopted the molecular markers for marker-assisted selection (MAS), quantitative trait loci (QTL) mapping and characterization of different quality traits in Alliums. This review presents details about the use of DNA markers in Alliums for cultivar identification, diversity studies, SSR development, colour improvement,...

Intra-varietal polymorphism of gliadins and glutenins within wheat varieties grown in the Czech Republic and its impact on grain qualityOriginal Paper

Václav DVOŘÁČEK, Jana BRADOVÁ, Ivana CAPOUCHOVÁ, Anna PROHASKOVÁ, Ludmila PAPOUŠKOVÁ

Czech J. Genet. Plant Breed., 2013, 49(4):140-148 | DOI: 10.17221/240/2012-CJGPB  

Using vertical electrophoresis, a set of 22 biotypes heterogeneous according to their gliadin alleles as well as their low-molecular-weight (LMW) and high-molecular-weight (HMW) glutenin subunits were identified in 10 winter wheat varieties registered in the Czech Republic. The effects of individual biotypes and their specific allelic compositions on 16 grain quality parameters were investigated. Inter-varietal differences in particular quality parameters (Zeleny sedimentation, farinograph water absorption, several values of the solvent retention capacity test) were significantly greater than the differences detected among biotypes of each variety....

Czech J. Genet. Plant Breed., 2013, 49(4):149-156 | DOI: 10.17221/117/2013-CJGPB  

Response of 35 spring wheat varieties and lines (of four Triticum species) to spray inoculation with Fusarium culmorum was evaluated in field experiments over three years (2010-2012). Data on mycotoxin deoxynivalenol (DON) content were complemented by symptom scores and determination of the percentage of Fusarium damaged kernels and percent reduction of thousand grain weight and of grain weight per spike due to infection. Resistance to Fusarium head blight (FHB) determined on the basis of the five mentioned traits was variable in all the examined genotype groups and very high only in the non-adapted check variety Sumai 3. The common...

The most important Brassica species, B. rapa, is naturally self-incompatible. Self-compatible mutants would be useful for dissecting the molecular mechanism of self-incompatibility (SI), a process that promotes outcrossing by recognizing and refusing self-pollens. The S haplotype in a new self-compatible B. rapa cultivar, Dahuangyoucai, was characterized for the first time in this study. Sequence analysis of the S-locus genes, SLG (S-locus glycoprotein), SRK (S-locus receptor kinase) and SCR (S-locus cysteine-rich protein) revealed that Dahuangyoucai...

Czech J. Genet. Plant Breed., 2013, 49(4):164-170 | DOI: 10.17221/32/2013-CJGPB  

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 characterize their genetic diversities. The numbers of alleles detected per locus ranged from 9 to 18 with a total of 105 alleles and an average of 11.7 alleles per locus, while the number of microsatellite genotypes varied between 10 and 23, indicating that there are abundant allele diversities in Chinese grape cultivars. The expected heterozygosity varied between 0.740 and 0.915 and the polymorphism information content...

In the present research, we aimed to detect and evaluate the level of long terminal repeat (LTR) retrotransposons (WIS2, Wilma, Daniela, and Wham) intraspecific variability and intron polymorphism for β-amylase (BAMY) genes in 37 winter and 25 spring triticale cultivars coming from European countries and the USA and 5 Finnish rye cultivars. The triticale and rye genotypes differ significantly with respect to the patterns of the four explored LTR retrotransposons. A neighbour-joining dendrogram has separated all triticale and rye cultivars into three principal clusters: all winter triticale, all spring triticale and all rye cultivars. We have proved...

Czech J. Genet. Plant Breed., 2013, 49(4):175-177 | DOI: 10.17221/11/2013-CJGPB  

Fabian is a medium-late two-row feedin barley of winter habit developed at Agrotest Fyto, Ltd., Kroměříž, Czech Republic (breeders' rights holder) and registered in the Czech Republic in 2011. In the Official Variety Trials it showed high grain yields under intensive growing conditions (104.5%) and medium yields under low input conditions (101.1%). Fabian has the highest cold hardiness of the registered two-row winter barleys and regenerates very well in the spring. Its resistance to powdery mildew is very high (score 8.2 on a 1-9 scale). It has medium plant height, moderate resistance to lodging and large yellow kernel. The spike is long and of medium...
