| 0 | PI 560333 | WISFAL | Medicago sativa L. subsp. falcata (L.) Arcang. | United States | W6 | | | 1990 | DEVELOPED | PRE 03/06/1990 | | | | | Breeding material | Robust vegetatively and fertile in intrastrain or interstrain crosses with cultivated alfalfa M. sativa. Thus unrestricted gene flow from WISFAL to any desired cultivated tetraploid cultivar, strain or population. Typical of diploid M. falcata PI gp adapted to the North Central USA. Fall dormant. Broad based M. falcata synthetic and good source of genetic variation in plant morphology, and in reactions to disease and insect pests. | 1455305 | PI 560333 |
