“…Lamb et al (1994) andButró n et al (1998a) found that general combining ability is a signiÞcant source of variation in Þeld corn for ear resistance to European corn borer and to S. nonagrioides, respectively. Most studies of the genetics of stem resistance to European corn borer in Þeld corn showed that control was mainly additive, but that there was a dominant component (Scott et al 1964, Jennings et al 1974, Guthrie et al 1985. The inheritance of stem resistance to S. nonagrioides may also involve nonadditive components (Cartea et al 1999), although Butró n et al (1999b based on general and speciÞc combining abilities found that only additive effects were signiÞcant.…”

Sesamia nonagrioides Lefebvre is a major insect pest of maize (Zea mays L.) in northwestern Spain. The inheritance of ear resistance in field corn to this pest has not been studied. This work aims to determine the importance of genetic (additive, dominance, and epistatic effects) and environmental effects in the inheritance of ear resistance to S. nonagrioides. Three field corn inbreds (CM109, EP31, and EP42) were used as parents and two crosses (CM109 x EP31 and CM109 x EP42) were made. These inbreds show different ear resistance levels to S. nonagrioides, with CM109 more resistant than EP31 and EP42. For each cross, parents (P1, P2), F1, F2, and backcrosses to each parent (BC1 and BC2) were evaluated. Correlations among ear damage traits showed that general appearance of the ear should be useful indicator of ear resistance. Ear resistance was dominant to susceptibility and was transmitted from inbreds to their hybrids. The additive-dominance model fit the generation mean analysis for both crosses and the degree of genetic control varied depending on the cross and trait. For both crosses, additive and dominance effects were significant for most ear damage traits. Epistatic gene effects were significant for husk and shank damage, and gene effects for number and length of tunnels were not significant. Because ear resistance involved additive and dominance effects for this set of inbreds, breeding procedures based on both types of gene action should be effective.

“…T he european corn borer is an important pest of maize in temperate regions (Scott et al, 1964). When larvae emerge during anthesis, they feed initially on pollen in the leaf axils, then on the leaf sheaths and collars, and finally on the stalk and ear during later stages of their development (Guthrie et al, 1969; Mason et al, 1996).…”

Genetic Mapping and Analysis of Quantitative Trait Loci for Resistance to Stalk Tunneling by the European Corn Borer in Maize

et al. 2001

The European corn borer (ECB), Ostrinia nubilalis (Hübner), is an important pest of temperate maize (Zea mays L.). Damage to the stalk could be minimized by breeding for resistant genotypes but selection is hindered by a laborious phenotypic assay. Knowledge of the position of quantitative trait loci (QTL) conferring resistance to ECB tunneling could greatly simplify selection for this trait. This study was conducted to map QTL for resistance to ECB tunneling, plant height, and anthesis. Recombinant inbred lines of the maize single‐cross population B73×B52, were grown at two locations in Iowa in 1997 and 1998. Genotypic and phenotypic data were obtained from each line to perform the QTL analysis. Nine QTL were detected for ECB tunneling, and they were associated with 59% of the genetic variation. Genetic effects for decreased tunneling were derived from the resistant parent, B52, at six QTL. One digenic interaction was detected between QTL for ECB tunneling. Eight and 10 QTL were detected for anthesis and plant height, respectively. ECB tunneling was not significantly correlated with either trait. Several QTL for ECB tunneling reported herein, QTL for ECB tunneling in other maize populations, and QTL for resistance to leaf damage by insect pests of tropical maize are located at similar positions of the maize genetic map.

“…The partitioning of the variation among hybrids showed that effects due to general and specific combining ability were highly significant for both traits, but general combining ability accounted for 91% and 84% of the hybrid sum of squares for DIMBOA content and leaf feeding ratings, respectively. Scott et al (1964) used the least squares method of Mather (1949), the Design III method of Comstock and Robinson (1952), and the generation mean procedure of Hayman (1958), in which Gamble's (1962) notation was used. The resistant parent was CI31A and the susceptible parent was B37.…”
