Effects of the Gpc - B1 locus on high grain protein content introgressed into Argentinean wheat germplasm
Wheat grain protein content [GPC] is important for human nutrition and has a strong influence on the quality of pasta and bread. The objective of this study was to analyse the introduction of the Gpc-B1 allele into two Argentinean bread wheat cultivars. Near-isogenic lines were developed in 'Pr...

| 520 | |a Wheat grain protein content [GPC] is important for human nutrition and has a strong influence on the quality of pasta and bread. The objective of this study was to analyse the introduction of the Gpc-B1 allele into two Argentinean bread wheat cultivars. Near-isogenic lines were developed in 'ProINTA Oasis' and 'ProINTA Granar' using marker-assisted selection. Gpc-B1 lines showed a significant [P = 0.01] increase in GPC and a significant [P = 0.001] decrease in grain weight in comparison with control lines without Gpc-B1. Differences in yield were not significant [P = 0.49] between lines. Gpc-B1 lines significantly reduced [P = 0.02] straw nitrogen concentration at maturity and significantly increased [P = 0.02] the nitrogen harvest index. When data were analysed by genotype and environment, differences in some analysed parameters were found, indicating that Gpc-B1 expression may be affected by different genetic backgrounds and environmental conditions. These results suggest that the introgression of the Gpc-B1 allele into Argentinean wheat germplasm could be a valuable resource for improving GPC with no detrimental effect on grain yield. | ||
