One of the main wheat breeder's goals is determining specific genomic regions which control important agronomical traits. Association analysis is a new strategy with high resolution in plant molecular breeding that could be used to improve the efficiency of marker assisted selection (MAS) for finding important QTLs (quantitative trait loci) or genes. A set of 96 diverse wheat genotypes was phenotypically measured during three growing seasons (2006/07, 2007/08, 2008/09). Microsatellite markers located near important QTLs were carefully chosen in accordance with existing literature data to validate marker trait associations (MTA). Genomic DNA was extracted...

We studied differences in salt stress response between two parental maize genotypes and their hybrid of the first filial (F1) generation. We determined their membrane stability index in addition to the content of photosynthetic pigments, superoxide radical, Na+, proline and sugars and the activities of ascorbate peroxidase, catalase and glutathione reductase. The F1 hybrid, known as Pusa Early Hybrid Makka 3 (PEHM 3), showed a higher membrane stability index and chlorophyll content and lower superoxide radical and Na+ content than its parents, the sensitive CM 142 line and the tolerant CM 213 line. This heterosis...
Cytological investigation of anther development in DGMS line Shaan-GMS in Brassica napus L.Original Paper

The cytological mechanism of male sterility of Shaan-GMS, a natural mutant dominant genic male sterile (DGMS) line in Brassica napus L., is not well studied. Cytological observation was made on different-size buds of DGMS line 0A30A derived from Shaan-GMS line. The pollen mother cells (PMCs) of DGMS line 0A30A were degenerating at the beginning of meiosis and could not pass the anaphase I stage, with no dyads or tetrads formed, suggesting that the DNA damage checkpoint and spindle assembly checkpoint were activated in sterile anthers. During the meiosis process of sterile anthers in the sterile plants, several kinds of abnormal meiotic cells...

White clover (Trifolium repens L.) is an essential element of sustainable livestock systems in temperate climates because of its adaptability to a range of management and soil fertility conditions. The performance of 15 accessions of white clover collected in northern Spain, and of two cultivars, the medium-leaved Huia and the large-leaved California, grown as spaced plants in Galicia, and in sward plots in Asturias was compared over a period of two years. The data obtained were reduced to two principal components that cumulatively explained 92.4% of the total variance. Cluster analysis identified three groups of accessions that described...
Comparing the efficiency of sampling strategies to establish a representative in the phenotypic-based genetic diversity core collection of orchardgrass (Dactylis glomerata L.)Original Paper

Establishing a core collection that represents the genetic diversity of the entire collection with a minimum loss of its original diversity and minimal redundancies is an important problem for gene bank curators and crop breeders. In this paper, we assess the representativeness of the original genetic diversity in core collections consisting of one-tenth of the entire collection obtained according to 23 sampling strategies. The study was performed using the Polish orchardgrass Dactylis glomerata L. germplasm collection as a model. The representativeness of the core collections was validated by the difference of means (MD%) and difference of...
