Parental clones were selected based on progeny tests for one or more of the following traits: resistance to bacterial wilt, anthracnose, Phytophthora root rot. Parental clones were planted under cage isolation and intercrossed at Sloughhouse, CA to produce breeder seed.

2. DS309 has been tested in Wisconsin, Minnesota, Iowa, Kansas, Michigan, Illinois, and Ohio. It will be marketed in Midwestern states. The primary purpose will be for hay, green chop, and dehydration.

5. Breeder seed will be produced from cuttings of the parental clones in a cage as Syn. 1. Foundation seed will be produced from Breeder seed and Certified seed either from Breeder or Foundation seed. One generation each of Breeder, Foundation, and Certified seed class is recognized. A maximum of three years each is permitted on stands producing Breeder and Foundation seed with five years of Certified seed.

6. Certified seed will be produced in 1987.

7. Application will be made for Plant Variety Protection.
