Description:
One-hundred-ninty-seven roadside and field plants were selected in the years 1924, 1926, and 1928. They were grown in plant-to-row progeny tests. Pollination was partially controlled by removing undesirable rows or plants. Twenty strains were selected in 1928. From all the available material, 11 mass selections of similar growth and maturity were made and then increased. Considerable roguing was done in 1932. Some strains were distributed to farmers in 1933. In the spring of 1935 seven mass selections were composited under the name Evergreen.
