“…QTL located on chromosome 6 (6.04) which is also the location for other QTLs involved in diseases and pest resistance. For examples, two QTLs for Southwestern corn borer resistance (SWCB) on bin 6.04 [71], and on bin 6.06 [72], two QTLs for resistance to Fusarium moniliforme, an ear rot disease detected on bin 6.04 and 6.06 [73] or identified resistance genes, mdm1 for dwarf mosaic virus resistance (MDMV) [74], wsm1 resistance to wheat streak mosaic virus (WSMV) [75] and rhm1 conferring to resistance to Cochliobus heterostrophus, a fungul [76] etc. QTL for resistance to Aflatoxin (Aspergillus flavus) was detected on bin 9.01 [77].…”

Southern corn rust is one of destructive diseases in maize caused by Puccinia polysora Undrew. A mapping population of tropical sweet corn recombinant inbred lines (RILs) derived from a cross between hA9104 and hA9035 inbred lines were set up to detect quantitative trait loci (QTLs) involved in partial resistance to southern corn rust. Eighty nine RILs were used to evaluate resistance levels using nine-point relative scale (1-9) at Sweet Seeds, Suwan Farm, Thailand include combined analysis. A genetic linkage map was constructed with 157 SSR markers, with a total length of 2123.1 cM, covering 10 chromosomes. Broad-sense heritability of individual location ranged from 0.76 and 0.82 and combined across locations was 0.87. Multiple QTL mapping (MQM) was applied for the identification of the QTLs. Fifteen QTLs were detected on chromosome 1, 2, 5, 6, 9 and 10 in both locations and combined across locations. QTLs on chromosome 1, 5 and 6 were contributed by alleles of resistant parent hA9104 while others were contributed by alleles from the susceptible parent, hA9035. Phenotypic variance of each QTL explained ranged from 6.1% to 41.8% with a total of 69.8% -81.9%. QTL on chromosome 1, 6 and 10 were stable QTLs detected in both locations.

“…Fall armyworm larvae feed extensively on whorl leaf tissue, often resulting in crop losses. Genetic and quantitative trait loci analyses indicate that resistance to these Lepidoptera is a quantitative trait regulated by several genes (Williams et al, 1989;Khairallah et al, 1998). Traits such as high hemicellulose content, low protein content, and leaf toughness appear to be correlated with reduced larval growth (Williams et al, 1998).…”

A Unique 33-kD Cysteine Proteinase Accumulates in Response to Larval Feeding in Maize Genotypes Resistant to Fall Armyworm and Other Lepidoptera

et al. 2000

Plants respond to insect feeding with a number of defense mechanisms. Using maize genotypes derived from Antiquan germ plasm that are resistant to Lepidoptera, we have demonstrated that a unique 33-kD cysteine proteinase accumulates in the whorl in response to larval feeding. The abundance of the proteinase increased dramatically at the site of larval feeding after 1 hr of infestation and continued to accumulate for as long as 7 days. The 33-kD cysteine proteinase was most abundant in the yellow-green portion of the whorl-the normal site of larval feeding and the tissue that has the greatest inhibitory effect on larval growth in bioassays. The proteinase was expressed in response to wounding and was found in senescent leaves. It may be a marker of programmed cell death. The gene coding for the proteinase, mir1 , has been transformed into Black Mexican Sweet callus. When larvae were reared on callus expressing the proteinase, their growth was inhibited ‫ف‬ 60 to 80%. The expression of a cysteine proteinase, instead of a cysteine proteinase inhibitor, may be a novel insect defense mechanism in plants. INTRODUCTIONOver the past 25 years, maize inbreds resistant to feeding by larvae of numerous lepidopteran species have been developed from Antiguan germ plasm (Williams and Davis, 1982;Williams et al., 1990a). Inbreds derived from this germ plasm (Mp704 and Mp708) are resistant to feeding by fall armyworm ( Spodoptera frugiperda ), southwestern corn borer ( Diatraea grandiosella), European corn borer ( Ostinia nubilalis ), sugarcane borer ( D. saccharalis), tobacco budworm ( Heliothis virescens ), corn earworm ( Helicoverpa zea ), and other Lepidoptera. Fall armyworm larvae feed extensively on whorl leaf tissue, often resulting in crop losses. Genetic and quantitative trait loci analyses indicate that resistance to these Lepidoptera is a quantitative trait regulated by several genes (Williams et al., 1989;Khairallah et al., 1998). Traits such as high hemicellulose content, low protein content, and leaf toughness appear to be correlated with reduced larval growth (Williams et al., 1998). No studies have indicated conclusively that secondary products contribute to the resistance, but two-dimensional gel electrophoresis has indicated that the presence of 36-and 21-kD proteins in the whorl may be predictive of resistance (Callahan et al., 1992).Bioassays in which fall armyworm larvae are reared on lyophilized whorl tissues indicate that larvae reared on resistant material weigh ‫ف‬ 50% less than those reared on susceptible material (Williams et al., 1990b). Larvae reared on lyophilized whorl tissue from resistant genotypes are smaller, grow more slowly, and pupate later than those reared on similar material from susceptible genotypes (Chang et al., 2000). The major effect of this germplasm is to slow larval growth and development and to increase the amount of time larvae are vulnerable to predators and parasites.The same phenotype, a 50% reduction in larval growth, is apparent when larvae are reared on nonfriable callus ...

“…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). In a similar study, Samayoa et al (2015b) attributed such discrepancies to QTL by environment interaction effects and stressed the importance of making phenotypic evaluations in environments similar to those for which breeding materials are intended to be used.…”

Maize (Zea mays L.) is the staple food in Kenya, and mapping the qualitative trait loci (QTL) associated with resistance to maize stem borer pest is important towards marker assisted breeding for this quantitative trait. The objective of this study was to identify any QTL associated with resistance to Chilo partellus and Busseola fusca, the two important stem borer pests in maize production in Kenya. A total of 203 F 2:3 individuals from a cross between CML442, a stem borer susceptible maize inbred line and CKSBL10026, a stem borer resistant maize inbred line; and 152 SNPs were used for mapping the QTL. Data were collected on leaf damage, stem borer exit holes and stem tunneling length as putative stem borer damage traits. A likelihood odds ratio (LOD) scores of 3.0 and maximum recombination frequency of 0.50 were used to declare linkage. LOD scores between 2.5 and 2.9 were considered strong indications of a QTL. Resistance QTL for the three putative traits were detected on chromosomes 1-7 and 9 for both individual locations and stem borer species analysis. In B. fusca sites, one QTL for reduced stem tunnelling was revealed on chromosome 4 while in the C. partellus sites, one QTL for reduced stem tunnelling was identified on chromosome 4 and another for reduced stem borer exit holes was identified on chromosome 5. Phenotypic variances explained ranged from 6 to 10%, suggesting a need to validate these QTL using a larger population and in different environments.
