Some potential sources of FAW resistance in temperate maize germplasm identified or developed by maize breeding programs in the Americas
Germplasm | Description | References |
---|---|---|
Mp496; Mp701-Mp708, Mp713; Mp714; Mp716 | Temperate maize inbred lines with resistance to FAW developed in the USA by USDA-ARS (Mississippi). Of these, Mp496, and Mp701 to Mp708, were derived from Caribbean accessions—Antigua Gp1, Antigua Gp2D, Guadalupe Gp1A, and Republica Dominica Gp1. Mp713 and Mp714 were developed from CIMMYT’s Multiple Insect-Resistant populations | Scott and Davis (1981); Scott et al. (1982); Williams and Davis (1980, 1982, 1984, 2000, 2002); Williams et al. (1990) |
B49; B52; B64; B68; B96 | Corn borer-tolerant inbreds generated by Iowa State University, USA, through introgression of Maiz Amargo from Argentina into temperate maize. The most important inbred line among these was B68, which became widely used by the seed industry in the USA | Walter Trevisan, personal communication |
Three GEM (Germplasm Enhancement of Maize) inbreds, including XL370A | Derived from the introgression of germplasm from Uruguay, Cuba, and Thailand; showed resistance to FAW in the southern USA | Ni et al. (2014); Abel et al. (2020) |
CMS14C; CMS23 (Antigua x Republica Dominica); CMS24; MIRT (Multiple Insect Resistance Tropical) race Zapalote Chico, Sintetico Spodoptera, Caatingueiro Spodoptera, and Assum Preto Spodoptera | Since 1975, Embrapa-Brazil identified and described several sources of resistance to FAW in maize, while also investigating the chemical compounds that underlie these native resistance traits | Walter Trevisan, personal communication |
Brazilian maize lines with potential resistance to FAW | In work conducted from 1986 to 1993, Embrapa-Brazil identified potential sources of resistance to FAW based on evaluation of maize accessions in the Brazilian germplasm bank | Viana and Guimares (1997) |
