Recurrent selection may be an effective way to combine improvements in resistance to Fusarium ear rot with improved grain yield and lodging resistance. To test this hypothesis, three cycles of recurrent index selection based on evaluating S0:1 lines for Fusarium ear rot, grain yield, and lodging were implemented in a genetically broad‐based population. Direct intrapopulation response to selection in the target traits was measured by comparing lines sampled from Cycle 0 and Cycle 3 populations. In addition, indirect response for fumonisin contamination was also measured along with indirect response for agronomic traits when crossed to commercial inbred tester, FR1064. Results indicate significant direct gain from selection for Fusarium ear rot, but no significant gains for yield or lodging resistance. Indirect gains were also observed for Fusarium ear rot resistance in topcrosses to an unrelated tester line and for fumonisin contamination both within the selection population and in topcrosses. Our results are the first demonstration of the indirect effect of selection against Fusarium ear rot on reduction of fumonisin contamination. Heritabilities for target traits did not decrease over generations, indicating potential for further genetic gain from selection in this population.}, number={1}, journal={CROP SCIENCE}, author={Horne, David W. and Eller, Magen S. and Holland, James B.}, year={2016}, pages={85–94} } @article{eller_payne_holland_2010, title={Selection for Reduced Fusarium Ear Rot and Fumonisin Content in Advanced Backcross Maize Lines and Their Topeross Hybrids}, volume={50}, ISSN={["1435-0653"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-78650082599&partnerID=MN8TOARS}, DOI={10.2135/cropsci2009.11.0683}, abstractNote={Backcross breeding is an important method to improve elite cultivars for traits controlled by a small number of loci but has been used less frequently to improve quantitatively controlled traits. Resistances to Fusarium ear rot [caused by Fusarium verticillioides (Sacc.) Nirenberg (teleomorph Gibberella moniliformis Wineland)] and contamination by the associated mycotoxin fumonisin in maize (Zea mays L.) are quantitatively inherited. We backcrossed the more resistant but unadapted inbred GE440 for four generations to the susceptible but agronomically elite commercial inbred FR1064. A selected set of 19 BC4F1:3 lines had greater resistance to ear rot and fumonisin content than their recurrent parent FR1064. Topcrosses of the selected lines had greater resistance to Fusarium ear rot and similar grain yield compared to the topcross of the recurrent parent FR1064. We also genotyped selected lines at DNA markers linked to ear rot and fumonisin resistance quantitative trait loci (QTL) identified in the BC1 generation of this cross to determine which QTL demonstrated allele frequency shifts due to selection. Markers linked to QTL on chromosomes 1 and 4 inherited the GE440 allele significantly more often than expected by random chance.}, number={6}, journal={CROP SCIENCE}, author={Eller, Magen S. and Payne, Gary A. and Holland, James B.}, year={2010}, pages={2249–2260} } @article{eller_holland_payne_2008, title={BREEDING FOR IMPROVED RESISTANCE TO FUMONISIN CONTAMINATION IN MAIZE}, volume={27}, ISSN={["1556-9551"]}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-77956939673&partnerID=MN8TOARS}, DOI={10.1080/15569540802450326}, abstractNote={Maize grain infected by Fusarium verticillioides may contain the mycotoxin fumonisin, which is associated with livestock and human diseases. To reduce levels of fumonisin in grain, efforts are under way to identify sources of maize with increased resistance to fungal infection and fumonisin contamination. Field and laboratory techniques have been developed to measure both Fusarium ear rot and fumonisin contamination. Application of these techniques has led to the identification of resistant maize lines and facilitated genetic analysis of resistance to ear rot and fumonisin accumulation.
