Competitive Abilities Of Oat And Barley Varieties, B. D. Mcbratney, K. J. Frey

Journal of the Iowa Academy of Science: JIAS

Competitive ability of a plant genotype reflects its capacity to yield well and compete successfully for light, moisture, and nutrients when grown with similar or dissimilar genotypes. This trait is important to plant breeding because most breeding populations are propagated in mixed or competitive stands. The objective of this study was to assess the competitive abilities of oat and barley genotypes.

Two sets of oat and barley genotypes were evaluated for competitive ability. Set I consisted of five oat varieties, and Set II consisted of two barley and three oat varieties. Neither set, when averaged, showed over- or under-compensation with …
