Resistance to Seedcorn Maggot 1 in Snap Bean 2

Colored seeded snap bean, Phaseolus vulgaris (L.), lines PI 165426, PI 165435 and Cornell 2114–12 were resistant to the seedcorn maggot, Hylemya platura (Meigen), in laboratory and field tests. A colored seeded commercial variety, SpartanArrow, showed moderate resistance while all white seeded snap bean cultivars tested were susceptible. It appears that rapid emergence and/or hard seedcoat influence resistance to seedcorn maggot in snap beans.
