    Notes: Triticum aestivum L.) and rye (Secale cereale L.) have been associated with an increase in grain yield and a decrease in end-use quality in hard red winter wheat. Although demonstrated with a 1BL.1RS translocation, less information is available regarding the effect of 1AL.1RS translocations. The objective of this study was to determine the effect of 1AL.1RS translocation in hard red winter wheat on end-use quality traits and their stability across environments. From the heterogeneous 1AL.1RS wheat cultivar Nekota, 18 homogeneous 1A lines (non-1RS), 16 1AL.1RS lines, four composites (1A, 1AL.1RS, 1AL.1RS + 1A, and Nekota), and six cultivars were tested in eight Nebraska environments. The 1AL.1RS translocation increased flour protein content (5.5 mg g-1), but decreased flour yield (14.2 g kg-1), Mixograph mixing time (from 2.9-2.7 min), and Mixograph mixing tolerance rating (from 3.5-3.1). Despite higher flour protein content in 1AL.1RS lines, the 1AL.1RS translocation did not enhance other end-use quality traits. On the basis of linear regression, the 1A and 1AL.1RS lines had similar stability values for flour yield in all environments, while the 1AL.1RS lines had higher flour protein content in all environments. For Mixograph mixing time and mixing tolerance, the 1A lines were more responsive to the environment, while the 1AL.1RS lines had exceptional stability over all environments. The end-use quality of Nekota can be explained by a mixture of 1A lines with acceptable to good quality and 1AL.1RS lines with poor to acceptable quality.

    Notes: Secale cereale L.) chromosome one (1RS) has been associated with an increase in grain yield in hard red winter wheat (Triticum aestivum L.). This positive effect has been demonstrated when the 1RS arm is present in the 1BL.1RS translocation. However, little information is available regarding the 1AL.1RS translocation of yield and yield components and their stability across environments. Eighteen homogeneous 1A lines (non-1RS) and 16 1AL.1RS lines were randomly derived from the heterogeneous cultivar Nekota. These 34 line, four composites (1A, 1AL.1RS, 1AL.1RS = 1A, and Nekota), along with six check cultivars were grown in eight Nebraska environments. The 1AL.1RS translocation in the Nekota background increased kernel weight (3.3%) and grain volume weight (0.4%); had no effect of grain yield, kernels per spike, and anthesis date; and decreased plant height (1.2%) and number of spikes per square meter (2.9%). The 1A lines and 1AL.1RS lines were equally stable for grain yield, kernels per spike, spikes per square meter, and plant height. For kernel weight, the 1A lines were more responsive and tended to have heavier kernels under favorable environments, while the 1AL.1RS lines had heavier kernels under lower yielding environments. For grain volume weight, the 1A lines were more responsive than the 1AL.1RS lines, which had heavier grain volume weight under lower yielding environments. Hence, the 1AL.1RS translocation in Nekota was not beneficial for either agronomic performance or stability.
