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

Abstract

Abstract Rye introgressions are important contributors to the genetic diversity of wheat. In this study, we investigated the effects of a wheat-rye translocation 1RS.1BL in bread wheat on kernel and bran properties and mineral content. 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.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.1BL had 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 the translocation. The bran of the RILs without the translocation had higher values in terms of fat, starch, and phosphorus content. The results indicate that wheat- rye translocation 1RS.1BL has a significant effect on both whole wheat kernel and bran content, and can be used to enrich the content of wheat bran.
