G 2818


1.  G 2818 is a 199 plant synthetic variety. The 199 parental plants were selected for resistance to bacterial wilt within progenies derived from intercrossing 47 clonal selections. The 47 clones trace to as many experimental cage combinations developed following four or more cycles of field evaluation and recombination. Each experimental cage combination had been screened for one or more of the following: bacterial wilt, Phytophthora root rot, pea aphid and spotted alfalfa aphid. Source material traces primarily to Vernal, Atlantic, Saranac, Ranger and Ladak.


2.   G 2818 is a winter hardy adapted for use in the Midwestern and northeastern US for hay, haylage and dehydration purposes. G 2818 has been tested in Illinois, Iowa, Maryland, Nebraska, Ohio, Ontario (Canada), and Wisconsin, and will be marketed primarily in the northcentral and northeast regions of the US.


3.   Approximately 68% of the flowers are purple to light purple with 15% blue variegated, 15% blue-green variegated, 1% yellow and 1% cream. Midsummer growth is erect, with fall growth similar to that of Vernal.


4.  G 2818 has resistance to bacterial wilt, Fusarium wilt, pea aphid and spotted alfalfa aphid, moderate resistance to Phytophthora root rot and low resistance to anthracnose. It has not been evaluated adequately for reaction to stem nematode.


5.   Breeder seed (Syn 1) was produced on 199 selected plants at Bakersfield, California, in 1976. Sufficient foundation seed will be produced at Montrose, Colorado, for the life of the variety. One generation each of breeder (Syn 1), foundation (Syn 2) and certified (Syn 3) is recognized. A maximum of 3 harvest years are permitted for stands producing foundation seed and 5 harvest years for stands producing certified seed.


6.   Certified seed will be marketed in 1983.


7.   Application will not be made for Plant Variety Protection.
