Mapping of QTL for resistance to first and second generation of European corn borer using an integrated SNP and SSR linkage map

Abstract: The European corn borer (ECB, Ostrinia nubilalis Hübner) is a major pest of maize (Zea mays L.) in North America and Europe. In this study, we mapped and characterized QTL affecting the resistance to the first (ECB1) and second generation (ECB2) of ECB and plant height with the aid of 164 SNP and 88 SSR markers. A total of 144 testcross (TC) progenies of double haploid (DH) lines developed from a cross of two parental lines from the Stiff Stalk germplasm pool were tested at six different locations in the USA u… Show more

“…However, QTL for tunnel length by the European corn borer (ECB, Ostrinia nubilalis ) have been previously mapped to chromosomes 1 and 5 [ 18 , 23 25 ]. Krakowsky et al [ 26 ] and Orsini et al [ 27 ] also localized QTL for tunnel length and stalk breakage by ECB in the bin 6.05. As all favorable alleles for tunnel length in this study came from the subtropical line CML103, this inbred could clearly enhance the resistance of the line B73 by providing new alleles of resistance in chromosomes 1 and 5 and, even, in the chromosome 6 where it is known that the B73 line carries alleles associated with resistance to tunnel length by ECB [ 26 ].…”

“…However, due to non-availability of maps both from the online databases and the publications, we could not include some of the QTL experiments (Groh et al, 1998 ; Brooks et al, 2005 , 2007 ). We also did not consider experiments for which the maps were built using single nucleotide polymorphism (SNP) markers (Orsini et al, 2012 ; Mwololo, 2013 ; Samayoa et al, 2015a ; Munyiri and Mugo, 2017 ), because of a lack of shared markers with the other maps. Also, due to lack of similar markers with the consensus map, from the experiment by Méchin et al ( 2001 ), we could only project chromosome 7 containing one QTL.…”

“…Within integrated pest management, selection methods based on phenotypic evaluation can increase the resistance [2426]. However, those selection methods are time and labor consuming because artificial infestation is required to guarantee a uniform attack in all genotypes [27]. Selection methods based on genomic information are effective in increasing resistance and can reduce the labor required for larva management and data collection [2830].…”
