Abstract
ALTHOUGH admixtures in grain varieties are a bane to many agronomists, very little critical study of grain mixtures has been undertaken. Data already available (3)' suggest that the yields of varieties in mixed stands may not be correlated with those from the same varieties grown separately. This fact has a direct application to the bulked population method of breeding. Advocates of that method commonly assume that the forces of natural selection which favor the perpetuation of plants that are best fitted to survive the hybrid mixture will likewise sort out the types that will yield best when grown alone. Doubtless this assumption is correct when the undesired types are being eliminated by cold, disease, or other serious adverse factors, but in the absence of such factors valuable material is likely to be lost as a result of competition
