| Cultivar Name | Breeder(s) | Year of Release | Description |
| Cal Common 49 | EH Stanford | 1949 | Selection from the land race Cal Common; tolerant to alfalfa dwarf, susceptible to bacterial wilt. |
| Caliverde | EH Stanford, B Houston | 1951 | Backcrossing used to add bacterial wilt and pseudopeziza leafspot resistance. |
| Moapa | [OF Smith], EH Stanford | 1957 | Nondormant. Joint release by SWAG (Southwest Alfalfa Group: USDA, Arizona, and California); spotted aphid resistance. |
| Caliverde 65 | 1966 | Improved yield, with spotted aphid, stem nematode, and foliar disease resistance. | |
