5347LH

  1. 5347LH is an 11 clone synthetic variety. Parent clones were selected phenotypically for resistance to one of more the following pests bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose (race 1), Aphanomyces root rot (race 1), and potato leafhopper (PLH). In addition, parents were selected genotypically for forage yield, fall dormancy and forage quality. A modified backcrossing program was used to transfer the PLH resistant trait from germplasm releases KS94GH6, KS108GH5, and 81IND-2 to a commercial background. Germplasm sources are: M. falcata (7%), Ladak (7%), M. varia (29%), Turkistan (2%), Flemish (41%), Chilean (5%), KS94GH6 (3%), KS108GH5 (3%), 81IND-2 (3%).
    2.  
  2. 5347LH is adapted to and intended for use in the north central, east central, and Great Plains regions of the United States. It has been tested in Iowa, Illinois, Minnesota, and Wisconsin.
    3.  
  3. 5347LH is a very winterhardy, dormant cultivar with a fall dormancy similar to Ranger. Growth habit is erect in the summer, and semi-erect in the fall. Flower color in the syn. 2 generation is approximately 35% purple, 64% variegated, 1% cream with traces of white and yellow.
    4.  
  4. 5347LH has high resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt, Phytophthora root rot, and pea aphid; resistance to Verticillium wilt and Aphanomyces root rot (race 1); moderate resistance to stem nematode, spotted alfalfa aphid, potato leafhopper and blue alfalfa aphid. 5347LH has not been tested for resistance to root knot nematode.
    5.  
  5. Breeder seed (syn. 1) was produced on replicated cuttings of the eleven parent clones in the greenhouse in 1994 and 1995, and in cage isolation in 1995. Seed from all parents was bulked. Seed classes will be breeder (syn.1), foundation (syn. 2 or syn. 3) and certified (syn. 3 or syn. 4). Foundation seed may produced from breeder or foundation.. The second generation of foundation seed may be produced at the discretion of Pioneer Hi-Bred International, Inc. Limitations of age of stand will be three and five years respectively, for foundation and certified breeder seed. Pioneer Hi-Bred International Inc. will maintain sufficient levels of breeder and foundation seed for the projected life of the variety.
    6.  
  6. Seed was first marketed in the fall of 1996.
    7.  
  7. Application for Plant Variety Protection will be made, and the certification option will not be requested.
    8.  
  8. As a means of added varietal protection, information included with the Application for Review of Alfalfa Varieties for Certification may be provided to the PVP office.
