TNFORMATION on the flowering habit of alfalfa would •*• appear to be fundamental to seed production research, since flowering precedes the other complex mechanisms that lead to the seed harvest. Preliminary observations of plants in breeding nurseries at Madison, Wis., suggested that inherent differences in flowering habit existed, provided that sucking insects such as the tarnished plant bug, Lygus oblineatus (Say), the alfalfa plant bug, Adelphocoris lineolatus (Goezs), and the potato leafhopper, Empoasca jabae (Harris) were controlled. It was not known if the node at which the first flower appeared on the stem was a stable and significant morphological characteristic of the plant, or if it were variable according to environmental factors. Therefore, the experiment reported here was designed to study the nodal location of the first flowering rachis in different plants during the first and second growth.
