| 0 | PI 515954 | 'NITRO' | Medicago sativa L. subsp. sativa | Minnesota, United States | W6 | | | 1988 | DONATED | 02/10/1988 | | | | | Cultivar | High resistance to Fusarium wilt and the pea aphid Acyrthosiphon pisum. Resistance to Phytophthora root rot and to biotypes of spotted alfalfa aphid. Improved fall leaf disease resistance in the upper Midwest compared to most other non-dormant cultivars. Susceptible to anthracnose, bacterial wilt, verticillium wilt, and blue alfalfa aphid. Nonwinterhardy similar to Moapa 69 in fall growth. Intended as a special purpose alfalfa for use as a 1-year hay source and as a fall plow-down green manure crop. Nondormant characteristic provide 4-6 weeks of additional fall growth and N2 fixation compared to dormant varieties. Consistently produced similar or greater summer forage yields in the seeding year as compared to other nondormant and dormant varieties. Will not reliably survive most upper midwest winters but may survive during winters with snow cover and/or mild temperatures. | 1410890 | PI 515954 |
