“…The identification of markers makes it possible to subsequently achieve effective transfer of genes that control resistance to Fusarium rot into susceptible maize genotypes so as to create resistant genotypes and prevent losses. [21] The precise determination of the genomic position of QTL and of their gene effects is still an area of extensive quantitative genetic and biometrical research. [22] Based on the screening of polymorphism between resistance and susceptible parents of NC300 £ Gm1002 and GE440 £ Sd7 populations with seven SSR and one STS primers, population derived from NC300 £ Gm1002 gave 15 polymorphic markers and population derived from GE440 £ Sd7 gave 10 polymorphic markers.…”

“…[20] SSR analysis and PCR amplification A set of seven microsatellite primers were used in this study and the sequences are shown in Table 1 and were obtained from Pharmacia Biotech, HP79 NA, England. The sequences of these primers were obtained from maize GDB database (www.maizeegdb.com) [21] which reported in previous works to be linked to Fusarium ear and stalk rots.…”

Two maize populations (GE440 £ Sd7 and NC300 £ Gm1002) were used in this study. Molecular markers like simple sequence repeat (SSR) and sequence-tagged site (STS) were used to identify resistance genes linked to Fusarium ear rot (Fusarium verticillioides). Also, quantitative trait locus (QTL) mapping was used to detect resistance genes on maize chromosomes. The co-dominant microsatellite markers (bnlg1063, umc2082, bnlg1621, umc2013, bnlg1740, umc2059 and SSR85) and STS (STS06) were amplified polymorphic bands and candidate markers linked to Fusarium ear rot resistance genes in maize. Seven QTLs were identified ranging from 2 to 7 for each trait. QTLs were distributed on two chromosomes and associated with grain yield/main ear and 100 kernel weight. The present study indicated that microsatellite and STS primers might be useful for developing improved cultivars.

“…Furthermore, two QTLs on chromosomes 4 and 5 were present in both populations (Robertson-Hoyt et al, 2006 ). In an F 2 mapping population, Kozhukhova et al discovered a codominant marker, RGA11 , for FER on the short arm of chromosome 1 at 18.3 cM of the resistance locus (Kozhukhova et al, 2007 ). Ding et al investigated FER resistance in a recombinant inbred line (RIL) population of 187 genotypes, among which two QTLs on chromosome 3 were coincident across environments (Ding et al, 2008 ).…”

Identification of Fusarium verticillioides Resistance Alleles in Three Maize Populations With Teosinte Gene Introgression

et al. 2022

Fusarium ear rot (FER) is a common fungal disease in maize (Zea mays L.) caused by Fusarium verticillioides. Resistant germplasm resources for FER are rare in cultivated maize; however, teosintes (Z. mays ssp. parviglumis and Z. mays ssp. diploperennis), which are wild-type species of maize, have the potential to offer a novel source of resistance alleles to enhance pathogen resistance in modern maize. Therefore, the aim of this study was to identify favorable alleles that confer significant levels of resistance toward FER. Three populations of BC2F8 recombinant inbred lines (RILs) were developed by crossing two different teosintes, Z. diploperennis and Z. parviglumis, with maize inbred lines B73 and Zheng58, and were screened for FER resistance. We found that Z. diploperennis and Z. parviglumis had higher resistance toward F. verticillioides in the leaves than B73 and Zheng58. However, the resistance toward F. verticillioides in the leaf and ear was unrelated among RILs. FER resistance was positively correlated with grain yield in the B73 × diploperennis (BD) and Zheng58 × parviglumis (ZP) populations, partly because the quantitative trait loci (QTLs) of FER resistance and yield traits were located close together. Four coincident QTLs (qFERbd5.177, qFERbd10.140, qFERzp4.066, and qFERzp5.116) and two highly reliable resistance-yield synergistic QTLs (qFERbd10.140 and qFERzp4.066) were identified in the BD and ZP populations, opening up the possibility of breeding for FER resistance without reducing yield.

Ear rots caused by different Fusarium spp. are one of the most dangerous food and feed safety challenges in maize production. At present, the majority of the inbreds and hybrids are susceptible. Gibberella and Fusarium ear rots (caused by Fusarium graminearum and Fusarium verticillioides, respectively) are the two main diseases, but more than 10 further Fusarium spp. cause ear rots. Natural infection is initiated by a mixture of the local Fusarium spp
