Effects of the 1RS.1BL wheat-rye translocationon kernel and bran content of bread wheat (Triticum aestivum L.)

Abstract

In this study, the effects of rye translocation on some quality properties and mineral content of whole wheat kernel and bran were investigated.The plant material consisted of 147 recombinant inbred lines (RILs) and five control cultivars, including the parent. The genotypes were grown in Turkey at two different locations for two consecutive years. In the study, lines with and without rye translocation were determined by SDS-PAGE and PCR analysis, and the glutenin subunits of the lines at Glu-A1, Glu-B1, Glu-A3 and Glu-B3 loci were also analyzed. The protein, starch, fat, ash, dry matter, acid detergent insoluble fiber (ADF), neutral detergent insoluble fiber (NDF), potassium (K), phosphorus (P) and magnesium (Mg) contents of kernels and bran of the RILs were determined. Statistically significant differences were found between the genotypes in terms of all the examined characteristics except the amount of dry matter. The RILs carrying translocation 1RS.1BLhad a higher average ADF, NDF, protein content, ash content, K, Mg, and P contents of kernels, as well as a higher average ADF, NDF, ash, and K bran contents than the RILs without thetranslocation. The bran of the RILs without thetranslocationhad higher values in terms of fat, starch, and phosphorus content. The results indicate that wheat- rye translocation1RS.1BL has a significant effect on both whole wheat kernel and bran content, and can be used to enrich the content of wheat bran.
