“…In the recent past, the introgression and pyramiding of major genes/QTL for different traits through marker-assisted selection (MAS) has proved successful in wheat [17][18][19][20][21][22][23][24]. Several RFLP, SSR and CAPS markers were reported to be closely linked with high GPC locus (Gpc-B1) on the short arm of chromosome 6B [25][26][27][28].…”

“…According to a recent report, more than 60 genes/markers are being deployed for wheat improvement through MAS [33], of which more than 20 traits/genes belong to grain quality like gain hardness, dough strength and swelling volume [34]. Molecular markers for quality traits (protein content, pre-harvest sprouting tolerance, gluten strength and grain weight) are also being increasingly used in Indian wheat breeding program successfully [19,[22][23][24].…”

a b s t r a c tGrain protein content (GPC) in wheat has been a major trait of interest for breeders since it has enormous end use potential. In the present study, marker-assisted backcrossing (MABC) was successfully used to improve GPC in wheat cultivar HUW468. The genotype Glu269 was used as the donor parent for introgression of the gene Gpc-B1 that confers high GPC. In a segregating population, SSR marker Xucw108, with its locus linked to Gpc-B1 was used for foreground selection to select plants carrying Gpc-B1. Background selection, involving 86 polymorphic SSR markers dispersed throughout the genome, was exercised to recover the genome of HUW468. For eliminating linkage drag, markers spanning a 10 cM region around the gene Gpc-B1 were employed to select lines with a donor segment of the minimum size carrying the gene of interest. Improved lines had significantly higher GPC and displayed 88.4-92.3 per cent of the recurrent parent genome (RPG). For grain yield, selected lines were at par with the recurrent parent HUW468, suggesting that there was no yield penalty. The whole exercise of transfer of Gpc-B1 and reconstitution of the genome of HUW468 was completed within a period of two and half years (five crop cycles) demonstrating practical utility of MABC for developing high GPC lines in the background of any elite and popular wheat cultivar with relatively higher speed and precision.(http://creativecommons.org/licenses/by-nc-nd/3.0/).

Most important crop productivity traits, such as yield under normal and environmental stress conditions, are determined by a large number of genes, each with a small phenotypic effect. Genetic improvement of these traits through breeding or genetic engineering has been frustrating researchers in academia and industry. The reasons for this include the complexity of the traits, the difficulty of precise phenotyping and the lack of validated candidate genes. Different approaches to the discovery of the genetic architecture of such traits, such as Genetic Association Mapping and Genomic Selection and their engineering, are expected to yield benefits for farmers and consumers.
