Description
Voris A-77 was selected from a field Phytophthora nursery in Ames, Iowa. The 97 parent clones were selected in September from the varieties Atlas, Olympic and Vangard in approximately equal numbers for: 1) lack of root damage caused by Phytophthora root rot, 2) large branched roots, 3) general top vigor, 4) relatively free from yellowing caused by potato leafhopper, and 5) vigor and profuse flowering following transplanting to the greenhouse.
Voris A-77 is intended for sale in the central to upper midwest for hay, greenchop and dehy production. It has been tested in Iowa, Illinois, Indiana, Idaho, Nebraska, New York, Pennsylvania, Connecticut and Oregon.
Voris A-77 has approximately 95% blue and purple flowers and 5% variegated, and less fall dormancy than Saranac.
Voris A-77 has a high level of resistance to anthracnose, has resistance to bacterial wilt, moderate level of resistance to Fusarium wilt and a low level of resistance to Phytophthora root rot. It has not been adequately tested to determinc levels of resistance to pea aphid, spotted aphid and stem nematode.

Certified seed may be produced from either breeder or foundation seed. A maximum of two harvest years are permitted on stands producing foundation seed with five harvest years maximum on stands producing certified seed.
