Narrative
Provides a combination of a broad genetic base, pest resistance and production potential needed in alfalfa for the southern Great Plains. Result of the interpollination of 579 plants derived from the convergence of three lines of pest resistance breeding: 1)resistance to the blue alfalfa aphid, spotted alfalfa aphid, and phytophthora root rot. The percentages of seedlings exhibiting resistance after infestation with aphids collected in Oklahoma were: blue alfalfa aphid-OK 190=13, CUF 101(R)(12)=25, and Arc(S)=6; spotted alfalfa aphid-OK 190=55, Baker(R)=50, and Caliverde(S)=2. Based on parental sources, should provide resistance to bacterial wilt, verticillium wilt, fusarium wilt, anthracnose, phytophthora root rot, and pea aphid, and a low or moderate level of resistance to alfalfa stem nematode and aphanomyces root rot. Flower color predominately purple (>95%) with some variegated flowers and a trace of white and yellow flowers. Fall dormancy similar to Legend, approx. 4 (1 to 9 scale, where 9 is very non dormant).
