Southwestern corn borer growth on callus initiated from corn genotypes with different levels of resistance to plant damage


, : Southwestern corn borer growth on callus initiated from corn genotypes with different levels of resistance to plant damage. Crop Science 23(6): 1210-1212

Callus from embryos of seven maize hybrids in one experiment and eight in another was initiated and maintained on medium with an addition of 14 mg/l 2,4-D. When ~600 mg of callus had developed on each Petri plate, three first-instar larvae of Diatraea grandiosella were added to each plate. After one week, larvae developing on callus from some hybrids were significantly smaller than those on callus from other hybrids.
