Resistance to foliar-feeding insects has been identified within the germplasm collection. There strains-pi 171451, pi 227687, and pi 229358-have a high level of resistance to several foliar-feding insects. Thisresistance is demonstrated by less feeding and a slower growth rate and by a righer mortality rate of the larvae. In our breeding program, we screened against the soybean looper [Pseudoplusia includens (Walker)and later screened those selections against other foliar-feeding insects. No insect-resistant variety has been released, but progress is being made toward incorporating genes for resistance to foliar-feeding insects into types having good productivity along with resistance to major disease and nematode problems. |
