European corn borer and lace bug resistance
PI(s): Schultz, Peter B

Abstract: Identification of leaf pubescence as a morphological character lead to cultivar identification of lace bug resistance by azalea and cotoneaster. Studies identified stem diameter in garden chrysanthemums as a key factor in European corn borer resistance.
Description:
Research
that focused on the identification of economically important cultivars that
possess resistance to insect pests. A
common source of resistance, leaf pubescence, was found with species of
Cotoneaster and cultivars of azalea.
Narrow
stem diameter was found to be a resistance factor against infestation of
European corn borer in fall production of chrysanthemum. The
latter study contributed to the profitability of this crop, and its annual
production increased from 15,000 units to over 4 million.
