Narrative
1941 Report of the FIfth Corn Improvement Conference of the North Central Region: Stocky plants with large stalk. Leaves light green, somewhat erect, smooth and slightly spotted. Plants usually have 13 to 15 leaves with 5 or 6 above the upper ear. Silks green, glumes light red, antheres pink and stalk base red. Very long husks. Strong protandrous. Two eared. Sheds little pollen. Usually segregates for plants that die prematurely and fail to develop good seed. A recovered strain of CI23 with medium yellow endosperm color. The nonrecurrent parent was CI 4-8.
