One last corn for now: Tuxpeño. This is sort of like the Black Angus of Mexican corn: reliable, productive, and widely grown. Midwestern Dent corns trace a very significant portion of their genetics back to this breed (even moreso Southern Dents), and it has contributed significantly to tropical lowland maize improvement in sub-Saharan Africa, Central America, Venezuela, and Mexico.
This particular population is a long day converted mixture tracing back to E. E. Gerrish’s work at Cargill, Inc. in the 1970s. As with the other populations of his that I’m offering, he crossed Tuxpeño and earliness donors in such a way to give 15/16 tropical and 1/16 US genetics. Last year I crossed his population (Cargill Mexican Dent) with a different long day-adapted, 100% tropical strain, and that F1 hybrid is what I’m making available in 2021. Final genetics come out to 31/32 tropical and 1/32 temperate.
Tuxpeño is – put bluntly – a no frills workhorse. It’s not very pretty or novel, but it’s very reliable and a good fit for a proper field corn. The female used in the pedigree came from seed that pushed through a record heat wave back in 2012 (106’F in the shade), and it had good yield. The male has less of a problem with stalk rot and northern leaf blight, which helps cover for the female’s shortcomings vs. these diseases.
I’ll have seed to sell of this population in 2021.
Days to mid-bloom is roughly 58 down here, with another 45 for fully ripened grain. Plant height averages 6 feet. Roots and stalks are good. Resistance against southern leaf blight and southern rust is medium to high, much superior to heirloom Midwestern and Southern dents. Northern leaf blight resistance is fair but insufficient for severe outbreaks. Grain color ranges from white to yellow to orange. Grain texture includes dent, hard dent, semi-flint, and flint. I eventually want to convert this population into an orange dent, but feel free to select in a different direction if you so choose.
I hand-pollinated this corn for optimal purity, but I can’t rule out a few rogue contaminants. I used 300 female plants and 100 males.
