Broad sense heritability estimates (H) for ozone (O 3 ) insensitivity in four P. vulgaris F 2 populations were high (0.66–0.88) under artifical fumigation conditions. In the F 3 , under field conditions, broad sense H in two populations had declined to 0.16 and 0.21, probably as a result of the interaction of maturity and injury. The results suggest that selection for O 3 insensitivity in early generations should be conducted under controlled fumigation conditions followed by field evaluations as lines approach homozygosity.
