Abstract
Nineteen inbred lines representing 4 heterosis groups (Iodent, Lancaster, Mindszenpusta and Reid), and the 171 hybrids from crosses between them, were assessed in 1994-95 for infection by a complex of stem rot fungi. The most resistant inbreds were those of the Iodent group. Heterosis values of up to 31% were observed among the F1s for resistance to infection. Yield among the genotypes was directly influenced by their level of resistance.
