Location of Genes Conditioning Resistance in Corn to Leaf Feeding of the European Corn Borer¹

Abstract

Chromosomal interchanges were used to determine which chromosome arms of resistant corn inbreds, C.I.31A and B49, carry genes for resistance to European corn borer leaf feeding. All corn plants were infested manually with corn borer egg masses in field studies conducted in 1961 through 1964.Resistant inbred C.I.31A was found to possess a gene or genes contributing to resistance on the short arm of chromosomes 1, 2, and 4, and on the long arm of chromosomes 4 and 6. Resistant inbred B49 appears to have genes for resistance on these same chromosome arms (possibly allelic to those of C.I.31A) plus an additional gene for resistance on the long arm of chromosome 8.

Identification of Chromosomes that Condition Dhurrin Content in Sorghum Seedlings1

“…Even more than five allelic pairs may be involved because some of the limitations in the use of chromosomal translocations for determining the number of genes conditioning a character, as described by Scott et al (14), also would apply in the present study. For example, closely linked genes would probably be identified as a single gene, and unless a gene had a significant effect in the heterozygous condition, it would not be detected.…”

Quantitative trait loci for resistance to spotted and African maize stem borers (Chilo partellus and Busseola fusca) in a tropical maize (Zea mays L.) population

“…In maize, resistance to the European corn borer is conditioned in a similar manner, albeit with additive gene action accounting for the majority of the QTL than dominance and over dominance gene actions (Guthrie and Russell, 1989;Bohn et al, 2000;Krakowsky et al, 2004;Jampatong et al, 2002). Scott et al (1966) showed that resistance to the European corn borer, a lepidopteran pest just like C. partellus and B. fusca was conditioned by a relatively large number of genes with small effects on chromosomes 1, 2, 4, 6 and 8. The caution is that some QTL may not have been detected and, or, were dissimilar to those reported for related stem borers species due to the low heritability of the putative traits, and differences in trait characterization (Khairallah et al, 1998;Jiménez-Galindo et al, 2017).…”

“…However, though composite mapping is quite similar to simple interval mapping it possesses improved power because it includes additional genetic predictors, called ‗cofactors' that represent QTL elsewhere in the genome and which absorb background genetic noise (Van Eeuwijk et al, 2010). Multiple QTL mapping (MQM) method was used in this study because theoretically, it reduces the error (Scott et al, 1966;Arends et al, 2010). While association mapping (linkage disequilibrium mapping) is a recent and more reliable method of locating putative QTL, the method does not deal with a fixed population like interval and multiple QTL mapping but is based on a random and larger population (Yan et al, 2011).…”

Biology of the tropical corn borer, Ostrinia furnacalis (Guenee) in relation to host plant resistance research

“…Ibrahim (1954) and Scott et al (1966), using reciprocal translocations, found that several chromosome arms carried genes for leaf-feeding resistance. Scott et al (1964) determined the type of gene action involved in leaf-feeding resistance by using Fg, F^, and selfed backcross populations of CI31A(R) x B37(S) plus individual Fg plants of (CI31A x B37) x CI31A and Fg plants of (CI31A X B37) X B37; most of the genetic variance was of the additive type.…”
