Twenty‐one soybean genotypes [ Glycine max (L.) Merr.] were evaluated for resistance to ozone and 19 genotypes for sulfur dioxide in the greenhouse and growth chamber. ‘PI 157474’ was most resistant to ozone, but ranked 14 in resistance to sulfur dioxide. ‘York’ was most resistant to sulfur dioxide and ranked fourth when subjected to ozone. ‘Peking’ was least resistant to both phytotoxicants. Experimental conditions necessary to investigate inheritance of resistance to ozone were determined by fumigating soybean plants equally spaced in a growth chamber. Relative sensitivity of each of the parents at several stages of foliar development must be established before classifying the progeny.
