Narrative

Inbred corn line 991 is a yellow dent inbred particularly suited as a female and is adapted to the North central part of the United States. 991 can be used to produce hybrids from approximately 85 to 100 days relative maturity based on the Minnesota Relative Maturity Rating System for harvest of grain. Inbred line 991 has demonstrated good combining ability with families derived from OH43 or Iodent type backgrounds.
