Description
Trident is a 36 clone synthetic with parentage tracing to Apollo (23 clones), an NAPB Flemish germplasm pool (8 clones), WL 318 (4 clones) and an NAPB central germplasm pool (1 clone). Selections were made following an average of five cycles of screening for Phytophthora root rot resistance. In the fifth cycle of screening selection pressure was also applied for anthracnose resistance and seed yield potential.
Trident is intended for sale throughout the midwest for hay, greenchop and dehy production. It has been tested in Iowa, Indiana, Illinois, Idaho, Wisconsin and Nebraska.
Trident has approximately 99% blue and purple flowers and 1% variegated. It is similar to Saranac in fall dormancy.
Trident has a high level of resistance to Phytophthora root rot, and has resistance to bacterial wilt, and a moderate level of resistance to Fusarium wilt and anthracnose. It has not been adequately tested to determine levels of resistance to pea aphid, spotted alfalfa aphid, and stem nematode.
Seed production shall be limited to one generation each of breeder, foundation and certified classes. Breeder (Syn 1) seed was produced on cuttings of the 36 parent clones at Nampa, Idaho, with sufficient quantity for the life of the variety held in controlled storage. Certified seed may be produced from either breeder or foundation seed. A maximum of two harvest years is permitted on stands producing foundation seed with five harvest years maximum on stands producing certified seed. No restriction is placed on area of production of foundation or certified seed.
Seed will be marketed in the spring of 1979.
Application will be made for Plant Variety Protection but not under the provision that all seed must be certified.
