The ozone-sensitive and ozone-tolerant snap bean (Phaseolus vulgaris L.) lines were originally derived from a cross between Wade Bush (ozone-tolerant) and Oregon 91 (ozone-sensitive) (Reinert and Eason 2000). Progeny were screened in ambient-air field studies and ozone sensitivity was found to be a dominant genetic trait. Screening of selfed generations allowed selections of extremes in ozone sensitivity (KO Burkey, pers. comm.).
Sensitive line - S156; Resistant lines - R123, R331
