UC Cran 0801 was developed by Dr. Steve Temple at the University of California, Davis.
BREEDING HISTORY AND DESCRIPTION
Breeder seed of UC Cran 0801 represents the F9 progeny from selection and breeding of the 2000-2001 greenhouse cross 67A1, UCD selection “99 Chico, row 239-1” with the variety UC Canario 707. “99 Chico 239-1” was itself an F4 UC Davis Grain Legume Program selection, used only as a parent for crosses, from the 1995-96 UCD cross of CIAT line “AFR 298” to the Dark Red Kidney variety CDRK ’82.
This variety is well-adapted to the Central Valley of California, from San Joaquin County North to Glenn County. The anticipated primary use of 0801 is as a “dry package” bean, which is the principal current utilization of US-produced Cranberry beans.
PEST AND DISEASE RESISTANCE
UC Cran 0801 has been shown to be resistant to Bean Common Mosaic Virus (BCMV).
UC Cran 0801 has out-yielded Etna and Capri mostly due to less shattering during harvest and threshing.
SEED CLASSES AND PRODUCTION
Seed classes will be Breeder, Foundation, Registered, and Certified. Breeder seed may be increased by UCD geneticists/breeders, using reserve Breeder stocks. Foundation seed can be produced from the new Breeder stock. Reserve samples of the original 2010 headrows are also stored at UCD field HQ’s.
Foundation, Registered and Certified classes should only be produced in California’s Central Valley, due to the fact that variety maturity is too late for most other bean production areas, adaptation has not been tested, and affirmation of genetic purity would be difficult. Isolation of at least 100 feet from the nearest P. vulgaris field and garden snapbean is required to maintain genetic purity.
