/~ pointed out by Spoehr (4),~ the physiological processes associated with the synthesis of dry matter in plants have been investigated in detail. The application of the knowledge gained from these studies to plant breeding research should provide an opportunity to further evaluate the extent to which variations in physiological properties are associatedwith such factors as yielding ability. Since chlorophyll is an essential factor in the photosynthetic system, a further study of the relation, between the concentration of chlorophyll and yielding ability within various strains of crop plants may furnish data which would aid in the selection of superior strains. Sprague and Curtis (5) have studied the correlation between the amount of chlorophyll per ~oo sq. cm. of leaf area and total chlorophyll per plant to the yield of shelled grain and total dry matter in corn. In general, these investigators obtained correlation coefficients that were positive, but because of the small numbers of inbred strains and crosses used several of the coefficients are too low to be statistically significant when interpreted on the basis of Fisher’s (I) levels significance for small numbers. Therefore, it seemed esirable to make a further study of these relationships with several groups of material available in the corn improvement program.
