The original cross was made by the Centro Internacional de Agricultura Tropical breeding program of Dr. Steve Temple in 1984, and brought to California as the line "CAP 7" in a CIAT "VEF" shipment by Temple in 1991. CIAT records indicate that the pedigree of the cross was "84-VA-909 x PAD 2". "PAD2" is from the cross G 6616x (G 4523x (G4523x G7)).
BREEDING HISTORY AND DESCRIPTION
Canario 707 is relatively late (98-105 days from planting to cutting, depending on date of planting and growing conditions) which is consistent with the desires of the California industry for full-season varieties particularly adapted to the long California growing season. The flower color is a lavender/soft pink tone. Plant growth habit is a very strong bush (indeterminate) that usually shows strong secondary branching (sometimes in the upper canopy) that may even continue after the initiation of flowering. Row canopy cover and light interception is complete. Folliage (typical of the canario class) is a dull, soft green, and lighter than kidney and cranberry types. This (recessive) folliage color and plant growth habit make field elimination of outcrosses relatively easy for this class.
An important morphological characteristic of Canario 707 is its sensitivity to high temperature abortion, which was observed in this and many other lines in 1997-98. In the case of Canario 707, it generally results in a later, reduced set and later maturity.
It is anticipated that the variety would be recommended for the traditional common bean-growing areas of Linden/Farmington, and for most of the Sacramento Valley. It performed reasonably well in a non-replicated strip trial outside Arcata (Humboldt County), but will probably prove too late to successfully grow there every year. It is also anticipated that "Canario 707" will be of interest to direct market and "heirloom" producers because of its very unique grain color/size, and especially in areas where there is a growing Hispanic marketshare.
PEST AND DISEASE RESISTANCE
Canario 707 has been shown to be resistant to Bean Common Mosaic Virus (BCMV).
SEED CLASSES AND PRODUCTION
Breeder seed will be maintained by the UCD Bean Breeding Program. A limited volume of Foundation seed should be maintained by UCD Foundation Seed Program.
