Sundor
1. Sundor was developed by selecting approximately 120 plants for resistance to stem nematode from the cultivar Maxidor. These 120 plants were randomly intermated to produce Syn 1 seed which was used to produce breeder seed (Syn 2). The breeder seed was harvested in bulk from approximately 2,000 plants. Germplasm was derived from the following original sources: African 55%, Indian 20%, Turkistan 12%, Chilean 8%, Peruvian 2%, Ladak l%, Flemish 1% and M. varia l%.
2. Sundor is best adapted to low desert areas of California and Arizona where stem nematode is known to be a problem. It has been tested in Arizona and California and will be used for general forage production.
3. Sundor is a very non-dormant cultivar, similar to CUF lOl and flower color is 99% purple. It has less than 1% variegated, white, cream or yellow flowers.
4. Sundor has high resistance to stem nematode, spotted alfalfa aphid, blue alfalfa aphid, pea aphid and Fusarium wilt; moderate resistance to Phytophthora root rot. It has not been tested for reaction to anthracnose, bacterial wilt or Verticillium wilt.
5. Adequate breeder seed (Syn 2) was produced to last the life of the variety. Seed classes will be breeder, foundation (Syn 3 or 4) and certified (Syn 3, 4, or 5). Two generations of foundation seed may be produced at the discretion of Northrup King Co. Limitation on age of stand will be one, three and five years, respectively for production of breeder, foundation, and certified seed.
6. Certified seed will be offered for sale in 1987.
7. It is undecided whether PVP will be applied for.
