S timothy plants, as they approach maturity, tend to preserve the normal green color of their leaves longer than others. This tendency, observed in the course of timothy breeding at North Ridgeville, Ohio, through a period of several years,3 has been used as the basis of further selection aimed at improvement in the quality of hay. To determine the relation between the number of late-maturing leaves and the quality of hay, a special study was made in ~ 935. The factors considered in measuring quality were color of leaves, commercial grade, and protein content of the hay.
