Accession Names and Identifiers

'CI 21E'

Type: Cultivar name

Name was in NSSL data and agrees with the red cob. Evidently since a suffix could not be put on CIze 21 the accession CIze 21 designated the accession before being PI'd.

CI.21E

Type: Other or unclassified name

The 1950 Report of the Eleventh Corn Improvement Conference of the North Central Region uses this designation.

Millard, Mark J. Iowa State University

CI21E

Type: Other or unclassified name

Group: NC7.ZEA.STANDARD

Names added by NC7 to standardize maize name format for Zea. Many old names consist of a three or four letter abbreviated country or state followed by a number. The NC7 standard is to write out the full country or state when possible.

Millard, Mark J. USDA, ARS, NCRPIS

CIze 21

Type: Other or unclassified name

Group: CIZE

Corn (Zea mays) accessions with CI numbers at NSSL

Narrative

This inbred was developed by backcrossing CI.21 with Hy. CI.21 was develped by crossing C.H. Kyle's long-husk line K577C to Hy and giving a tall, late maturing line. Plants are shorter and appreciably earlier than CI.21 but is a little later and more vigorous than Hy. CI.21E has yellow kernels and a red cob differing from CI.21 which has medium yellow kernels on a white cob. CI.21E is blight resistant while CI.21 is susceptible to kernel rots and northern leaf blight.
