'UC Southwest Gold'

Type: Cultivar name

Narrative

UC Southwest Gold has an heirloom-like seed coat similar to Zuni Gold, but with I-mediated resistance to bean common mosaic virus (BCMV) and yields 60% higher than its heirloom parent. Culinary evaluations have shown that it displays cooking properties comparable to Zuni Gold. Field trials were carried out on certified organic ground. UC Southwest Gold will contribute towards satisfying an increasing market demand for more productive and economical heirloom-type common beans.
Plants produce white flowers and green stems, and grow upright until pod set, facilitating weed cultivation. The variety often lodges later in the season. UC Southwest Gold is relatively early, with 50% flowering by 44 days after planting and plot maturity occurring at 85 days in Davis in 2019. The variety has strong and uniform dry-down when stands are dense. Plants are indeterminate but very compact, expressing a type IIIa growth habit. All seeds include white and gold, but the ratio of the two colors is environmentally influenced. UC Southwest Gold has a 100 seed weight of 33g, similar to 32g for Zuni Gold.
UC Southwest Gold had statistically significantly higher yields than Zuni Gold in the multi-location, multi-year trials. UC Southwest Gold yielded an average of 2,060 kg/ha compared to 1,288 kg/ha for Zuni Gold, a 60% increase. UC Southwest Gold plants did not display any symptoms of BCMV infection in any year, whether in the field or in the greenhouse. In contrast, Zuni Gold plots at every evaluated field site showed symptoms of BCMV. UC Southwest Gold and Zuni Gold are not significantly different in flavor or cooked appearance. This indicates that UC Southwest Gold has significantly improved agronomic properties relative to Zuni Gold, without a loss of cooking quality.
