Encouraging results have been obtained from research to develop hybrid corn that is adapted to the climate and soil of the South. The above plants are a single cross between T13 and T61 at the Tennessee Agricultural Experiment Station. Tennessee Hybrid No. 10,

another contribution from the Tennessee station, is the most popular white hybrid of the Neal Paymaster type. Good husk protection to prevent weevil damage can be inherited from a parent plant, a quality that should be bred into corn for Southern States.

American wheat growers have constantly faced the need for new varieties so as to reduce losses from drought, disease, insects, and other hazards. A few of the improved varieties are pictured here. Pawnee being grown for seed increase at Lincoln, Nebr.; it resists leaf and stem rusts, loose smut, and hessian fly. Comanche (lower left), also a hard red winter wheat, resists stinking smut. Both Pawnee and Comanche mature from 3 to 6 days earlier than Tenmarq. A new bunt resistant wheat for the Columbia Basin is Orfed. It yields high, resists smut, has stiff straw that combines well, and it can be seeded in fall or spring.Lemhi, a new spring variety for land is under irrigation.

RESEARCH ON COTTON has proved that different varieties of it behave alike in some ways, but there are differences in structure, strength, fineness, and uniformity of the fiber of different varieties and species. Soil moisture, temperature, fertility, and other factors also have a bearing, but variety is by far the most important factor in cotton. In some cases, the strength of 22s yarn from different selections of about the same length and staple differ as much as 40 percent.

Manufacturers are now buying cotton on the basis of variety and they select varieties that meet their specific needs. To help cotton breeders select and increase seed for a desired purpose, the Department makes available to them a fiber and spinning-test service. The breeding work and studies of inheritance by the Department in cooperation with State experiment stations have produced strains that surpass many now being grown. In the above picture, a plant breeder selects individual plants from the breeding plot for yield, quality, and other superior characteristics.
