Narrative
Unimproved non-cornbelt, flour-flint flour population altered from short to long day, cornbelt adaptation. Population with 94% recovery of tropical germplasm. Stalks brittle. Ears slender with low kernel row numbers. Kernel colors white-yellow-red. Although the three Chavantes populations were presumably collected from the same Indian tribe, Chavantes, they differ considerably in maturity and gross appearance under Hawaiian growing conditions. Initially Red Chavantes was crossed with the source of earliness, Early Russian. During a series of three backcrosses to tropical, Red Chavantes was always involved and four additional representatives of this race were added at the second backcross. Black Chavantes was involved at the first backcross only. Interpollination among the different sources was practiced following each backcross. An adapted population was formed through phenotypic recurrent selection out of the third backcross generation. There is a lower than average tolerance to heat, drought, and high plant density. Best results are obtained where plant densities are kept below 40,000 plants per hectare.
