Assessment of genotype × environment effect on groat protein and beta-glucans contents in a Moroccan collection of wild tetraploid oat species of Avena magna Murphy and Terrell. and A. murphyi Ladiz

The study explores the nutritional and genetic aspects of Avena magna and Avena murphyi oat genotypes, emphasizing their significance in breeding programs to release new cultivars conceived for human consumption. Oats have long been recognised for their nutritional benefits, contributing to daily caloric needs, and offering potential health advantages. The study focuses on the genetic diversity found in wild and weedy oat species, specifically A. magna and A. murphyi, which possess valuable agricultural traits such as disease resistance, earliness, and high groat nutritive quality. With a rich diversity of oat species in Morocco, this research aims to assess groat proteins and beta-glucans contents in A. magna and A. murphy genotypes and investigate the effect of the interactions Genotype × Environment as well as their origin on these qualitative traits. The analysis reveals dynamic trends in proteins and beta-glucans contents, emphasising the impact of specific origins, such as Ouezzane and Benslimane, and their adaptability to varying environmental conditions. The study suggests these findings are crucial for oat breeding programs seeking resilient and nutritionally rich cultivars. Furthermore, the research underscores the intricate relationship between genetics and the environment, providing valuable insights for developing sustainable and adaptable oat cultivars conceived for human consumption.
