Most cultivars of snap beans (Phaseolus vulgaris) currently available in the US were evaluated for resistance to oxidant (ozone) air pollution in field plots at Beltsville and Salisbury, Maryland, in one or more of the past 8 years. Of 387 cultivars and breeding lines tested, 270 were classified resistant, 86 intermediate, and 31 susceptible. Responses of seedlings with one expanded trifoliate leaf to high concentrations of ozone revealed statistically significant differences among cultivars. The correlation between leaf injury induced by ozone on seedlings and ozone injury on the same cultivars as adult field-grown plants was low (r = .20) but significant. 13 references, 3 tables.
