R. O. Weibel and J. W. Pendleton APRIMARY objective in most winter wheat breeding programs is to develop varieties with superior lodging resistance. While it is generally known that the yield and quality of winter wheat grain is reduced by lodging, little information is available as to the actual amount. Results from artificial lodging studies using a simple wire technique have been reported for oats (4) and for barley (1, 2, and 5). No such studies have been found for this technique for wheat. However, a. method of pinching or breaking individual culms was used in one wheat lodging study (3). The objective of the experiment reported herein was to use the wire technique to assess the effect of lodging on yield and certain quality characteristics when applied at different stages during kernel development. Such information will furnish a more accurate evaluation of the lodging factor when it occurs under natural field conditions. MATERIALS AND METHODS
