2. In an inbred strain of Yellow Horsetooth two selfed ears were found to be segregating for rootless. Dr. Jenkins pointed out this character last June in our breeding field. The rootless segregates have all the characteristics of plants of rt rt type (Jenkins, 1930; Cornell Memoir 180, p. 20, 1935). If crosses with rt stock prove it to be the same mutant it will be the second occurrence of this distinct root mutation. Our strain has never been grown in close proximity to any rt stock.
