Narrative
A681 is an early version of B73 developed by an early by late procedure, backcrossing to B73 three times. Silking is about 3-4 days earlier than B73. It combines well with Lancaster germplasm and some early B14 types. Out-performs B73 by 30% with about 5% less moisture. High kernel row with small seed. Lodging similar to B73. Adapted to South-central and North-central Minneosta. (University of Minnesota Agriculture Experiment Station Release of Corn Inbred Lines, May 1987)

PRODUCTIONHeterotic GroupThe heterotic group an accession belongs to for breeding purposes. When forming hybrids that demonstrate heterosis (high performance), accessions from different heterotic groups should be crossed.SS - (SS) Belongs to the stiff stalk combining group. This group represented by Iowa Stiff Stalk Synthetic (BSSS) or inbred B73 combines best with inbreds designated as non-stiff stalk (NS). MAIZE.CURATOR.AND.MAIZE.EXPERT.REVIEW Not Available
