PLANT RESISTANCE Evaluation of Conventional Resistance to European Corn Borer (Lepidoptera: Crambidae) and Western Corn Rootworm (Coleoptera: Chrysomelidae) in Experimental Maize Lines Developed from a Backcross Breeding Program
Plant resistance is a promising control method for the two most damaging insect pests of maize, Zea mays L.: the European corn borer, Ostrinia nubilalis (Hübner), and the western corn rootworm, Diabrotica virgifera virgifera LeConte. Fifteen experimental lines of maize, derived from a backcross breeding program designed to introgress resistance to European corn borer from Peruvian maize into tw...
متن کاملGenetic basis of resistance to fall armyworm (Lepidoptera: Noctuidae) and southwestern corn borer (Lepidoptera: Crambidae) leaf-feeding damage in maize.
Leaf-feeding damage by first generation larvae of fall armyworm, Spodopter frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), and southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera: Crambidae), cause major economic losses each year in maize, Zea mays L. A previous study identified quantitative trait loci (QTL) contributing to reduced leaf-feeding damage by these insects in the mai...
متن کاملQuantitative Trait Loci Conferring Resistance to Fall Armyworm and Southwestern Corn Borer Leaf Feeding Damage
ern corn borer resistance. Few plant breeders have access to insect rearing facilities, which are necessary to Southwestern corn borer (Diatraea grandiosella Dyar) and fall maximize selection efficiency. Negative traits tend to armyworm [Spodoptera frugiperda (J.E. Smith)] damage ratings were measured on an F2-derived maize (Zea mays L.) population segregatmask genetic gains in resistance at ea...
متن کاملEffect of environment on resistance to the European corn borer (Lepidoptera: Crambidae) in maize.
The European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is a major pest of maize, Zea mays L., in many temperate parts of the world. Genotype-by-environment interaction effects can make relative performance unpredictable and may hamper selection for resistance to European corn borer. The objective of this study was to determine the effect of environment on genotypic react...
متن کاملImpact of plant resistance on southwestern corn borer (Lepidoptera: Crambidae) biology and plant damage.
Southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera: Crambidae), is a major insect pest of corn, Zea mays L., in the southern United States. Germplasm lines with resistance to southwestern corn borer have been developed and released by the USDA-ARS. Two single-cross hybrids produced by crossing germplasm lines with resistance to southwestern corn borer and a susceptible single-cros...
