in Maize (Zea mays L.) C. O. Grogan, Patricia Sarvella, J. O. Sanford, and H. V. Jordan THE influence of cytoplasmic male sterility on various agronomic characteristics, including morphology, has been observed in a number of plants. Reports, though differing at points, all agree that cytoplasmic male sterility influences plant behavior. Detasseled corn grown under certain environmental or cultural conditions (4) behaved much like cytoplasmic male-sterile corn grown under similar conditions (Chinwuba et al. 2). Duvick (3) pointed out certain dissimilar relationships. Rogers and Edwardsen (7) showed that male-sterile hybrids yielded more under drought stress than their normal counterparts. However, Josephson and Kincer (6) showed that the yield of malesterile hybrids had no advantage over the fertile hybrids. They studied also the effect of sterile cytoplasm on certain other agronomic characteristics. Sanford et al. (8) presented evidence on the influence of sterile cytoplasm. on nitrogen accumulation. Since the utilization of cytoplasmic male sterility and restoration of fertility in the production of hybrid maize seed, most studies have dealt with aspects of production. Few, if any, critical data have dealt with dry matter accumulation in different plant parts of cytoplasmic male-sterile lines or hybrids and their normal counterparts.
