| 0 | PI 217404 | Argentine Pop | Zea mays L. subsp. mays | Argentina | NC7 |  | | 1954 | COLLECTED | PRE 05/04/1954 | | | | | Landrace | A small-eared, tiny-kernelled, prolific variety from the Argentine. It has a red pericarp. It is similar to the grave popcorns of Argentina. This accession was part of the donor's collection of maize varieties demonstrating extreme variation. They were considered as endemic and were maintained as germplasm for breeding work and were part of the Anderson and Brown collection of "standard exotics". They were originally collected from farmers who maintained them as open-pollinated varieties. | 1177450 | PI 217404 |

Varieties like this accession crossed with "northern flints" to give us modern Corn Belt Dent. Corn Belt Dent is the classification of maize grown in the largest U.S. acreage. This accession was part of the donor's collection of maize varieties demonstrating extreme variation. They were considered as endemic and were maintained as germplasm for breeding work and were part of the Anderson and Brown collection of "standard exotics".

Cells are difficult to smear for chromosome observations. Chromosomes have low knob numbers. Ears have high row numbers and are more or less fasciated. This accession was part of the donor's collection of maize varieties demonstrating extreme variation. They were considered as endemic and were maintained as germplasm for breeding work and were part of the Anderson and Brown collection of "standard exotics". They were originally collected from farmers who maintained them as open-pollinated varieties. | 1177454 | PI 217406 |

It is very similar in ear morphology to the ancient popcorns of Peruvian graves. This accession was part of the donor's collection of maize varieties demonstrating extreme variation. They were considered as endemic and were maintained as germplasm for breeding work and were part of the Anderson and Brown collection of "standard exotics". They were originally collected from farmers who maintained them as open-pollinated varieties. | 1177455 | PI 217407 |
| 4 | PI 217408 | Longfellow Flint | Zea mays L. subsp. mays | Iowa, United States | NC7 |  | | 1954 | DONATED | 05/04/1954 | | | | | Landrace | A typical yellow 8-rowed Northern Flint. It can be successfully grown as far south as Saint Louis, Missouri. This accession was part of the donor's collection of maize varieties demonstrating extreme variation. They were considered as endemic and were maintained as germplasm for breeding work and were part of the Anderson and Brown collection of "standard exotics". They were originally collected from farmers who maintained them as open-pollinated varieties. | 1177458 | PI 217408 |
| 5 | PI 217409 | Maiz Chapalote | Zea mays L. subsp. mays | Mexico | NC7 |  | | 1954 | COLLECTED | PRE 05/04/1954 | | | | | Landrace | Primitive popcorn from western Mexico. It shows close similarity to teosinte in various characters. Ears have a narrow cob, with kernels of an irregular shape and a brown pericarp. Chromosomes have large knobs and the number of knobs are variable from plant to plant. This accession was part of the donor's collection of maize varieties demonstrating extreme variation. They were considered as endemic and were maintained as germplasm for breeding work and were part of the Anderson and Brown collection of "standard exotics". They were originally collected from farmers who maintained them as open-pollinated varieties. | 1177459 | PI 217409 |

It is drought resistant and early maturing in late plantings. Seedlings have a long mesocotyl and plants have slender leaves. This accession was part of the donor's collection of maize varieties demonstrating extreme variation. They were considered as endemic and were maintained as germplasm for breeding work and were part of the Anderson and Brown collection of "standard exotics".
