Wheat genetic resources - how to exploit?

Boerner, A., Leibniz Inst. of Plant Genetics and Crop Plant Research et al. [dec2011]

It is estimated that world-wide existing germplasm collections contain about 7.5 million accessions of plant genetic resources for food and agriculture. Wheat (Triticum and Aegilops) represents the biggest group comprising 900 000 accessions. However, such a huge number of accessions is hindering a successful exploitation of the germplasm. The creation of core collections representing a wide s ...

Detection of QTLs for important agronomical traits in hexaploid wheat using association analysis

Brbaklic, L., Institute of Field and Vegetable Crops et al. [jan2013]

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 phe ...

This paper presents the results of studies on the genetic variability of HMW glutenin subunits in wheat cultivars created in Novi Sad (Serbia, Yugoslavia). By the method of SDS-PAGE electrophoretic analysis, eleven alleles at Glu-1 loci (3 alleles at the Glu-A1, 6 at the Glu-B1, 2 at the Glu-D1) were determined. Typical HMW glutenin composition in wheat cultivars was 2(x), 7+9, 5+10 and 1, 7+9 ...

Evaluation of genetic diversity in wheat breeding material using microsatellite markers

Brbaklic, Lj., Institut za ratarstvo i povrtarstvo et al. [2010]

Genetic variability of 50 wheat genotypes was analyzed using 16 microsatellite markers. According to literature data, the markers associated with important agronomic traits were chosen for the analysis. Total of 111 alleles were detected, ranging from 3 in locus Xgwm601 up to in Xpsp3094. The average value of polymorphism information content (PIC) was 0,619, indicating a high level of polymorp ...

Phenotypic variability and stability of harvest index and spike index in 40 wheat genotypes, originated from four different regions in 35-50 belt of World north hemisphere (Russia and Ukraine, Far East, North America, Cemtral and South Europe) were investigated. Based on the results of phenotypic variability and stability of analysed characters, the genotypes were detected which could serve as ...

Molecular evaluation of genetic variability of wheat elite breeding material

Brbaklić, Lj., Institut za ratarstvo i povrtarstvo et al. [2009]

Estimation of genetic variability of breeding material is essential for yield improvement in wheat cultivars. Modern techniques based on molecular markers application are more efficient and precise in genetic variability evaluation then conventional methods. Variability of 96 wheat cultivars and lines was analyzed using four microsatellite markers (Gwm11, Gwm428, Psp3200, Psp3071). The markers ...

2008, the Institute of Field and Vegetable Crops in Novi Sad (Serbia) will celebrate its 70th anniversary. The Institute breeding program included small grains from its very foundation back in 1938 and 372 cultivars of these species have been developed since as a result. The highest amount of breeding work has been done on wheat and barley. The dominance of NS wheat and barley cultivars began ...
