"DREVIOUS studies at this Station (5, 6, 9) have evalu-^ated the effects of location of seed production and of management practices on gene frequency in Pilgrim Ladino Clover. Attention was first focused on the original parent clones of this variety and the Syn 1 generation produced by them. The clones were found to differ markedly in their seed setting ability, and the production of the clones was differentially affected by the area in which seed was produced and by the period of the year in which seed was harvested. Daylength as affected by latitude or by season seems to be the most important differentiating factor, but temperatures prior to flower initiation are also of some importance. The net result of these influences is that some
