Prowler
1. Prowler is a synthetic variety composed of 11 plants, one each from the varieties Spredor, Travois and Kane, and the remaining 8 from five different experimental populations which had been developed for persistence, bacterial wilt resistance, vigor and creeping rooted habit during the years 1959 to 1975. Germplasm sources included Travois, Rambler, Vernal, Drylander, Kane, Roamer, Glacier and Cardinal. Equal amounts of hand pollinated greenhouse seed was bulked from each of the 11 plants to produce Prowler (Syn 2).
2. The primary areas of usage for Prowler will be the Northern and Central regions of the U.S. for pasture interseeding or establishment of permanent or semipermanent pastures. Prowler has been tested in Iowa, Missouri, Tennessee, Wisconsin, Minnesota, Nebraska and Montana.
3. Prowler has a relatively high percentage of plants that exhibit the ability to reproduce and spread by underground roots. At Washington, Iowa, under space planted conditions it has a high percentage of creeping rooted plants. Prowler is more fall dormant than the cultivar Vernal and flower color is approximately 36% purple or violet, 61% variegated and 3% cream-yellow.
4. Prowler has high resistance to bacterial wilt, low resistance to Fusarium wilt, pea aphid and spotted alfalfa aphid. It is susceptible to anthracnose and has not been adequately tested to determine its level of resistance to Phytophthora root rot and stem nematode.
5. Seed classes will be breeder, foundation and certified. Adequate breeder seed (Syn 2) has been produced to last the expected life of the variety. Limitation on age of stand for producing the various classes of seed will be two, three & five years for breeder, foundation and certified respectively.
6. Certified seed will be available in 1981.
7. Application will be made for Plant Variety Protection.
