Narrative
Late maturing line for the U.S. Heat units to pollen shed are 1500, compared to 1400 for Mo17 in 2001. Plant and ear height are 1.99 and 0.67 m, compared to 1.82 and 0.7 m for Mo17. Leaves erect, and usually 6-7 leaves above the ear-bearing node. Tassel compact and dense with a central spike and 10-14 lateral branches. Heavy pollen producer for 3-4 days. Anthers yellow and green silks. Flower synchronization excellent, with silk emergence seldom delayed more than one day after pollen shed. Plants produce many sun-red brace roots to the 2d or 3d node above the crown. Produces a large girthy ear with 16 or 18 rows of very hard, medium-sized orange kernels on a white cob.
