Greenhouse Screening for Resistance<br />
to <strong>Leaf</strong> <strong>Scorch</strong><br />
• Resistance to blueberry leaf scorch in greenhouse<br />
screening agreed with observed field resistance for<br />
most cultivars.<br />
• Emerald was more susceptible to Xylella fastidiosa<br />
in the greenhouse than in the field.<br />
• Star appeared to be more resistant in greenhouse<br />
tests than has been observed in the field.<br />
• Differences between greenhouse and field<br />
observations could be due to host specificity <strong>of</strong><br />
strains, agressiveness <strong>of</strong> strains, or loss <strong>of</strong> virulence<br />
in some strains during culture.
