“…They concluded that smut-resistant varieties were the best method to prevent the disease. 12 These results were confirmed by Immer and Christensen. 9 ' 11 Conversely, it was postulated that the location of smut galls on the plants depended on the strain of U. maydis and on the genotype of maize lines.…”

Huitlacoche is the ethnic name applied to the young fruiting bodies (galls) of the fungus Ustilago maydis, which causes common smut of maize (Zea mays L). Biologists and agronomists have historically used U. maydis as a model to study a wide array of genetic, physiological, ecological, and phytopathological phenomena. In Mexico and other Latin American countries, huitlacoche has been used traditionally as human food, being highly regarded as an interesting dish or condiment. The food potential of huitlacoche is described here in terms of its chemical composition, which includes carbohydrates, proteins, fats, vitamins, and minerals. In addition, essential amino acids (especially lysine) and fatty acids (linoleate) are present in huitlacoche in considerable levels, adding to its nutritional attributes. The feasibility of growing U. maydis in submerged agitated culture has yielded a variety of fermentation products, including essential amino acids, proteins, vitamins, and flavorings, among others. Recent interest in developing huitlacoche as a cash crop has come from increasing acceptance by the North American public, who prize it as a new delicacy. However, research efforts are still needed to determine the biological factors involved in the establishment of U. maydis as a pathogen on the maize plant. This review deals with the role of huitlacoche as a food source, implicating the biological components that will determine the development of technologies for large scale production.

“…Consequently, field infections are usually the result of dikaryons of a diverse genetic constitution. 12 - 106 Tisdale and Johnston reported differences in the parasitic behavior of smut from different sources. 106 Some cultures of smut are somewhat more pathogenic than others.…”

“…Members of ASA were active in many areas of research during this era, including soil fertility, crop physiology and management, and breeding. Papers in the Journal of the American Society of Agronomy during this period included “The effect of fertilizers on yield and market condition of corn” (Ellett and Wolfe, 1922), “Planting rate and spacing for corn under southern conditions” (Mooers, 1920), “Relation between yield and ear characters in corn” (Hutcheson and Wolfe, 1918), and “Breeding corn for resistance to smut ( Ustilage zeae )” (Garber and Quisenberry, 1925). Although presumably the goal of most of these activities was to ultimately increase yield, it is clear from Fig.…”

Comparison of Corn and Soybean Yields in the United States: Historical Trends and Future Prospects

Developing successful strategies to ensure future increases in crop yield depends, in part, on a better understanding of the basis for past increases. To this end, I compared historical yield trends of two dissimilar crops—corn (Zea mays L.), a high yielding C4 grass, and soybean [Glycine max (L.) Merr.], a moderate yielding C3 legume—in high (Iowa, Illinois, Indiana) and low (Kentucky, Missouri, Tennessee) yield environments. Average state corn yield changed very little from 1866 to 1930, an era of low‐input agriculture, but it increased rapidly from 1950 to 2005 in all states as the low‐input system gave way to a high‐input system that utilized commercial hybrids, manufactured N fertilizer, herbicides, and higher plant populations. Soybean yield, first available in 1924, increased steadily from the beginning until 2005. Corn yield increased faster than soybean yield in the early decades of the high‐input era (mean growth rates of corn were 3.3 vs. 1.5% per year for soybean with a slight advantage for both crops in high yield states) in all six states, but for the rest of the era (up to 40 yr), corn and soybean yields grew at nearly the same rate (1.8% per year for corn, 1.4% per year for soybean with a slight advantage for the low‐yield states). Thus, the efforts to improve the plant (plant breeding) and production environment (better management practices) had essentially the same affect on these two very dissimilar crops.

“…Observations on corn smut (Ustilago zeae) were made during the seven years, 1917 to 1923, inclusive, at the United States Dry-Land Field Station at Akron, Colo., which is operated by the Office of Dry-Land Agriculture Investigations of the Bureau of Plant Indus- try, U. S. Department of Agriculture. Akron is situated at an elevation of about 4 •. ~6o feet in northeastern Colorado in the western portion of the Great Plains area.…”
