'UC Southwest Red'

Type: Cultivar name

Narrative

UC Southwest Red has an heirloom-like seed pattern similar to the landrace ‘Anasazi™’, but demonstrates resistance to bean common mosaic virus (BCMV) and has yields 53% higher than Anasazi™. Evaluations of flavor and cooked appearance demonstrate that it has comparable culinary quality to Anasazi™. All on-farm evaluations were conducted on certified organic ground.
UC Southwest Red produces seeds that are phenotypically similar to Anasazi™. These seeds retain an interesting red and white mottled pattern after cooking. Plants have a compact, indeterminate, type IIIa habit, with green stems and white flowers. The variety has an upright growth habit until after flowering, facilitating weed cultivation. Lodging is common during pod set. 50% of plants flowered by 41 days after planting and plots were ready to harvest at 86 days after planting in Davis in 2019. Plants mature and dry strongly and uniformly at the end of the season. UC Southwest Red’s compact habit provides high yields with a comparatively small amount of vine and leaf material. All UC Southwest Red seeds have a white and red mottled pattern, but the ratio of the two colors is variable based on environment. The average 100 seed weight is 31g, compared to 35g for Anasazi™.
In the 2018-2019 field evaluations, UC Southwest Red yields averaged 1,872 kg/ha compared to 1,226 kg/ha in Anasazi™, a statistically significant increase of 53%. UC Southwest Red plants did not show any BCMV symptoms in any on-farm or greenhouse evaluation in any year. In contrast, BCMV was identified in Anasazi™ at every evaluated field site. The flavor and cooked appearance of UC Southwest Red and Anasazi™ are not significantly different, indicating that UC Southwest Red maintains culinary properties similar to Anasazi™.
