Fifty-nine potato cultivars and selections were planted in replicated plots at two Ohio locations each in 1975 and 1976. Evaluations of ozone “speckle leaf” injury were made during August and yields were recorded in October. A broad range in resistance to ozone injury was noted at both locations with later-maturing entries generally being more resistant. Entries severely injured by ozone had a reduced yield. The relative resistance of most entries was constant in all tests.

Durante los años 1975 y 1976 se plantaron ensayos replicados incluyendo 59 cultivares y clones selectos de papa en dos localidades cada año del estado de Ohio. Durante el mes de Agosto se hicieron observaciones sobre el daño producido por ozono (“hojas pecosas o moteadas”) y las evaluacoines de rendimiento se realizaron en Octubre. En ambas localidades se notó un amplio rango de resistencia al daño producido por el ozono, apreciándose que generalmente las entradas más tardías fueron las más resistentes. Se produjo una reducción en el rendimiento en las entradas dañadas severamente por el ozono. La resistencia relativa de la mayoría de entradas fue consistente en todas las pruebas.
