| 0 | PI 618810 | 'Zapalote Chico 2451F' | Zea mays L. subsp. mays | Florida, United States | NC7 |  | | 2001 | DEVELOPED | | | | | | Cultivar | White kernel floury corn with a purple plant. Improved silk resistance to the fall armyworm (FAW) (Spodoptera frugiperda) and the corn earworm (CEW) (Heliocoyerpa zea), and the corn silk fly (CSF) (Euxesta stigimatias). Resistance is based on chemical antibiosis and conferred by the flavone glycoside, maysin and its chemical analogues. Maysin is present in the emerging silk at levels of 0.52% of fresh silk weight, above the 0.20% considered toxic to ear feeding lepidopterans. Early population often maturing in less than 75 days in tropical and subtropical climates. Does not appear to be photoperiod sensitive. | 1613720 | PI 618810 |
