QTL mapping and candidate genes for resistance to Fusarium ear rot and fumonisin contamination in maize / V. Maschietto, C. Colombi, R. Pirona, G. Pea, F. Strozzi, A. Marocco, L. Rossini, A. Lanubile. - In: BMC PLANT BIOLOGY. - ISSN 1471-2229. - 17:1(2017 Jan 21), pp. 20.1-20.21. [10.1186/s12870-017-0970-1]
Abstract:
Fusarium verticillioides is a common maize pathogen causing ear rot (FER) and contamination of the grains with the fumonisin B1 (FB1) mycotoxin. Resistance to FER and FB1 contamination are quantitative traits, affected by environmental conditions, and completely resistant maize genotypes to the pathogen are so far unknown. In order to uncover genomic regions associated to reduced FER and FB1 contamination and identify molecular markers for assisted selection, an F2:3 population of 188 progenies was developed crossing CO441 (resistant) and CO354 (susceptible) genotypes. FER severity and FB1 contamination content were evaluated over 2 years and sowing dates (early and late) in ears artificially inoculated with F. verticillioides by the use of either side-needle or toothpick inoculation techniques.
