Narrative
One of the most impactful discoveries in this screening was that ‘Illinois 76’, a Pyrus ussuriensis × P. pyrifolia hybrid, produced a number of progeny that were highly resistant to fire blight (van der Zwet et al., 1974b). ‘Illinois 76’ was a selection that originated from the Rutgers University pear breeding program. Quote from Gottschalk et al. 2024. Direction of cross is unknown.
