Abstract Background: Pea (Pisum sativum) is a prevalent cool season crop that produces seeds valued for high protein content. Modern cultivars have incorporated several traits that improved harvested yield. However, progress toward improving seed quality has received less emphasis, in part due to the lack of tools for easily and rapidly measuring seed traits. In this study we evaluated the accuracy of single-seed near-infrared spectroscopy (NIRS) for measuring pea seed weight, protein, and oil content. A total of 96 diverse pea accessions were analyzed using both single-seed NIRS and wet chemistry methods. To demonstrate field relevance, the single-seed NIRS protein prediction model was used to determine the impact of seed treatments and foliar fungicides on protein content of harvested dry peas in a field trial. Results: External validation of Partial Least Squares (PLS) regression models showed high prediction accuracy for protein and weight (R2 = 0.94 for both) and less accuracy for oil (R2 = 0.75). Single seed weight was not significantly correlated with protein or oil content in contrast to previous reports. In the field study, the single-seed NIRS predicted protein values were within 1% of an independent analytical reference measurement and were sufficiently precise to detect small treatment effects. Conclusion: The high accuracy of protein and weight estimation show that single-seed NIRS could be used in the dual selection of high protein, high weight peas early in the breeding cycle allowing for faster genetic advancement toward improved pea nutritional quality.

Aim. The variation of protein content and its relationship to agronomic traits of introgression wheat lines were studied to determine the differentiating ability of environment, a value of breeding traits from new sources and the relevancy of assessment methods. Methods. Growing plants under different conditions was combined with the laboratory methods for determining quality. Results. An average protein content of the lines (9.7–15.5 %) was higher in the wide-row crop and in drouth years, and the range of variation was wider in dry years in the wide-row crop, but in favorable years in the solid crop. A stable positive correlation of protein content with gluten content (0.87–0.96) and sedimentation value (0.58–0.90), and the negative correlation with yield was established. Conclusions. The parameters of plant resistance to diseases and harsh agricultural backgrounds, the determination of protein content by several methods and the differentiating ability of the environments with optimal conditions and a high agricultural background should be used for selection and objective evaluation of material. Weather conditions may limit the use of some indicators as breeding traits. The method of near-infrared spectroscopy requires constant calibrations, following measurement instructions may overestimate the protein content and affect the efficiency of the selection process. Keywords: wheat, introgression lines, protein content, methods.
