DK-187
1. The breeder seed cage was established in Woodland, California, from seed of six parental populations which were bulked prior to planting. These six parental populations trace to selections within various varieties and breeding populations for resistance to one or more of the following pests: Phytophthora root rot, spotted alfalfa aphid, and blue aphid. Origin of the six parental populations can be traced to the varieties CUF-101, WL-512, 167, 572, 581 and an experimental synthetic of Peruvian origin.
2. DK-187 is adapted to those areas of the Southwestern U.S. where non-dormant varieties are grown. It can be used for hay, greenchop or dehydration. DK-187 has been tested in the San Joaquin and Sacramento Valleys of California.
3. Flower color is light to dark purple and fall dormancy is similar to Moapa 69.
4. DK-187 has high resistance to spotted alfalfa aphid and Fusarium wilt, resistance to Phytophthora root rot, moderate resistance to blue aphid, and low resistance to bacterial wilt. Resistance characteristics to pea aphid and stem nematode have not been measured.
5. Breeder (Syn. 1) seed was produced in cage isolation at Woodland, California, in 1980. Seed increase is on a limited generation basis with one generation each of breeder and certified seed classes and two generations of foundation seed class. Breeder (Syn. 1), foundation (Syn. 2 or 3) and certified classes (Syn. 2, 3 or 4) with limitations on age of stand of 1, 2 and 6 years respectively, will be recognized. Sufficient foundation seed of this variety for its projected life will be maintained in environmentally controlled storage by the breeder.
6. Certified seed will be marketed in December, 1983.
7. Application for protection under the U.S. Plant Variety Protection Act is contemplated and the certification option will not be requested.
