“…Even in early studies of aneuploides and chromo some substitution lines [24,104,105,106] it was shown on that the GPC trait can be influenced by not only structural genes identified in different chromo somes but also by regulatory genes [107]. Using ditelo somic cultivar Chinese Spring Wanous et al [108] demonstrated that 79 of 164 assumed regulatory genes (48%) show a significant effect on the expression of genes encoding high molecular glutenins (excluding dose effects of structural genes).…”

Studies on identification and localization of quantitative traits for grain protein content (QGpc loci) on chromosomes in Triticum aestivum and Triticum durum are reviewed. Association of QGpc with vari ous traits of morphology, physiology, adaptation and tolerance to abiotic and biotic stress is shown. Genetic and environmental QGpc contexts that should be taken into account when using molecular markers in breed ing for the grain protein content are considered.

“…Grain protein has a significant influence on processing quality, such as dough rheological properties, baking quality, and endproduct attributes (Buck et al, 2007). The level of global protein yield in wheat has remained relatively stable, despite an increase in productivity of this crop (Zlatska, 2005). Wheat quality improvement is a major challenge for many breeding programs.…”

ABSTRACT. High molecular weight glutenin subunits (HMW-GS) play an essential role in wheat processing quality. In this study, we evaluated the genetic pattern with HMW-GS composition between generations and examined whether agronomic and quality traits were correlated with each other. A wheat (Triticum aestivum L.) cultivar with high protein content and 2 cultivars with low protein content were subjected to a reciprocal cross. Sixteen agronomic and 4 quality characteristics were investigated. A total of 216 seeds from each F2 generation were chosen randomly and analyzed for HMW-GS composition using sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Agronomic and quality characteristics were not significantly different between reciprocal crosses, indicating no cytoplasmic effect on the characteristics studied. The separation ratio of 2 HMW-GS loci was 9:3:3:1, indicating no linkage between any 2 loci. The novel HMW-GS N was detected in cultivar R145, which did not follow the Mendelian segregation ratio. A Glu-A1a(1) band was not detected in 1 individual from Tian8901xR145. Average grain weight per spike was significantly correlated with quality characteristics and may be a suitable criterion for selecting high protein content in wheat breeding programs.

“…The remarkable success in the genetic improvement of grain yield of common wheat varieties over the past 50 years was not accompanied with comparable progress in grain quality (Van Lill and Purchase, 1995). According to Zlatska (2005) grain protein content in wheat was among the characters that suffered from intense selection, the narrow genetic base of germplasm in use has been considered the main reason. Knowledge of genetic diversity patterns allows plant breeders to better understand the evolutionary relationships among accessions, to sample germplasm in more systematic fashions, and develop strategies that incorporate useful diversity in their breeding programs (Bretting and Widrlechner, 1995) .Information about genetic diversity and relatedness in the available germplasm and among elite breeding material is a fundamental element in plant breeding.…”

Randomly amplified polymorphic DNA (RAPD) markers were used to study the genetic relationships and similarity among four wheat genotypes (two local cultivars, namely Giza-168 and Sakha-69 and two recombinant inbred lines one with low grain protein percentage "GPP" and the other with high grain protein percentage. Amplifications using five primers produced RAPD fingerprints with varying numbers of bands which ranged in size from 196 bp to 2519bp.The number of amplified DNA fragments per primer ranged from 4 to 10 with a mean of 8.6 bp. The primers have amplified 43 bands, out of which 33 bands (76.7%) were polymorphic. Twenty RAPD markers were found to be genotype specific with eight being specific for the low GPP line, six markers for the high GPP line, four markers for Giza-168 and two markers for Sakha-69. The mean genetic similarity among the four genotypes was 0.714 ranging from 0.656 to 0.829. The genetic relationships among the four genotypes estimated by UPGMA cluster analysis based on the RAPDderived data indicated that a relatively small number of RAPD primers could be used for distinguishing wheat genotypes according to protein percentage. The results suggested that identification of RAPD molecular markers associated with genes influencing GPP would allow wheat breeders in Egypt to select for GPP independent of enviro-nmental effects.
