“…In fact, yield of MAS-pop did not differ significantly from yield presented by PSB-Yield and tunnel lengths of MAS-pop and PSB-TL were similar (Tables 2 and 3). These results validated the positions and effects of QTL for tunnel length detected by Ordás et al (Ordas et al, 2010) and encourage us to persevere in using marker-assisted selectionMAS approaches for simultaneous improvement of yield and resistance to stem borer attack; a task rarely accomplished using conventional breeding tools (Butron et al, 2014;Bohn et al, 2003). However, as resistance to stem tunneling by MCB has been proved to be highly polygenic, based on many genes with small effects that could get undercover in QTL studies, more promising results are expected to be attained if marker-assisted selectionMAS is rather based on genome-wide than on QTL approaches (Foiada et al, 2015;Ordas et al, 2009;Ordas et al, 2010;Samayoa et al, 2015;Samayoa et al, 2014;Jímenez-Galindo et al, 2017).…”

Two decades of investigations on maize resistance to stalk Mediterranean corn borer (Sesamia nonagrioides Lefebvre, MCB) corn borers have shown that breeding for increased resistance to stem tunneling by MCB often resulted in reduced yield because significant genetic correlation between both traits exists in some backgrounds. Unlike phenotypic selection, marker-assisted selection (MAS) could differentiate markers linked only to one trait from those linked simultaneously to increased resistance yield potential and reduced yieldsusceptibility to the pest. In the current study, the suitability Con formato: Fuente: Cursiva Con formato: Fuente: Cursiva Annals of Applied Biology 2 of marker-assisted selectionMAS for improving resistance to stem tunneling without adverse effects on yield has been tested. The unfavorable genetic relationship between yield potential and susceptibility could be overcome using MASThe unfavorable genetic relationship between yield and resistance could be broken using marker-assisted selection. Gains obtained using marker-assisted selection MAS were weak because genetic variance explained by the quantitative trait loci (QTL) was low but results encourage us to persevere in using maker information for simultaneous improvement of resistance and yield especially if genome-wide approaches are applied. Approaches to detect QTL are widely used, but studies on the suitability of markers linked to QTL for performing marker-assisted selectionMAS has have been mostly neglected.

SUMMARYThe direct response of a divergent selection programme for total cell wall ester-linked diferulate concentration in maize pith stalk tissues and its indirect effect on cell wall degradability and corn borer resistance have been previously evaluated. Since increased total diferulate concentration is expected to improve crop performance in response to corn borers, the objective of the present research was to evaluate the indirect response of the divergent selection for diferulates on agronomic traits under corn borer infestation. For this purpose, five maize populations with contrasting total diferulate concentrations were evaluated four environments for performance under protected and infested conditions. Measured traits were: days to anthesis, days to silking, plant height, stalk lodging, grain moisture at harvest and grain yield. High diferulate populations showed a significant reduction in anthesis (precocity), and were 11 cm taller than the starting population, while low diferulate populations were 9 cm shorter, and showed nearly 1 t/ha lower grain yield than the original and high diferulate populations. The analysis showed that cycles of selection were positively correlated with flowering, plant height and grain yield. The infestations with borers produced >1 t/ha of reduction in grain yield; although the higher diferulate populations showed a better performance under infestation than the low diferulate populations. This positive effect on the grain yield by increasing diferulate content can be considered an extra in order to breed for resistance to corn borers.

“…Exploitation of the genetic variability of maize for resistance to corn borer attack could be a complement and/or alternative to the use of Bt- corn. Indeed, some breeding programs developed in the Misión Biológica de Galicia (Pontevedra, Spain) have been successful in developing materials with partial resistance to the MCB (Sandoya et al, 2008 ; Butrón et al, 2014 ), although an indirect, undesirable effect was also achieved: yield reduction (Sandoya et al, 2008 ; Butrón et al, 2012 , 2014 ).…”

QTL Mapping for Yield and Resistance against Mediterranean Corn Borer in Maize

Introduction: The Mediterranean corn borer (MCB), Sesamia nonagrioides, is a major pest of maize, Zea mays, in Mediterranean countries, inflicting significant kernel yield losses. For that reason, it necessary to know the genetic mechanisms that regulate the agronomic and resistance traits. A quantitative trait loci (QTL) mapping study for yield, resistance against MCB attack, and other relevant agronomic traits was performed using a recombinant inbred line (RIL) population derived from the cross A637 × A509 that is expected to segregate for yield, and ear, and stalk resistance to MCB. 171 RILs were evaluated in 2014 and 2015 at Pontevedra, Spain, along with the two parental inbreds A637 and A509 using a 13 × 14 single lattice design with two replications. A genetic map with 285 SNP markers was used for QTL analysis. Our objectives were to detect QTL for resistance to MCB and tolerance-related agronomic traits, to gain insights on the genetic relationship between resistance to MCB attack and yield, and to establish the best way for simultaneously improving yield and resistance to MCB.Results: Twelve significant QTL were detected for agronomic and resistance traits. QTL at bins 1.10 and 5.04 were especially interesting because the same allelic variant at these QTL simultaneously improved yield and insect resistance. In contrast, in the region 8.04–8.05, QTL showed opposite effects for yield and resistance. Several QTL for indexes which combine yield and resistance traits were found especially in the region 10.02–10.03.Conclusions: Selecting genotypes with the favorable allele of QTL on chromosome 5 (bin 5.01) will decrease tunnel length without affect yield, silking and plant height and QTL on the region 5.04 could be used to improve stalk resistance and yield simultaneously. An allele of QTL on bin 9.07 will increase ear resistance to MCB attack but it could produce later varieties while favorable allele in region 1.10 could improve ear and stalk resistance and yield without secondary negative effects. The region 8.03–8.05 mainly but also the region 10.02–10.03 and 5.04 may play an important role to elucidate the association between yield, other agronomic traits and MCB resistance.
