(Results of more than 500 will not return images.)

This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as

When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.

The more information you provide, the better the search will be.

0PI 619430Tx807Zea mays L. subsp. mays Texas, United StatesNC7EAR2001DEVELOPEDBreeding materialMaize parental line with white grain, high lysine and hard endosperm. Carries the opaque-2 mutation and has a hard flinty endosperm. Adapted to Southern U.S. areas. Intermediate maturity~2days later than B73 in the College Station, TX conditions. Flowers earlier than tropical and subtropical QPM inbreds. Ears thin and short with few kernel rows. Cobs white (pp), and thin. Kernels flint with bright white color (yyy). Plants short with nice aspect and green color. Ear placement is low. An intermediate pollen shedder and has poor grain yield. Lysine contents of 0.48 grams over 100 grams of sample. Constitutes at 60% more lysine content than standard non-QPM inbreds. (0.30 g/1000 g sample). Inbred line per se appears to be resistant to Aspergillus flavus infection and aflatoxin. Hybrids have desirable agronomic traits showing shorter plants, lower ear placement, earlier maturity, lower moisture content at harvest, less root and stalk lodging, easier pericarp removal, greater test weights, and greater hardness than other QPM hybrids. Hybrids have lower weight of 1000 kernels, and greater susceptibility to common smut.1619477PI 619430
