The more winter-hardy varieties of the semiprostrate pasture type and semierect hay type have maintained satisfactory stands and seed yields in the Lake Champlain region of New York and Vermont, in the Great Lakes region of southern Ontario and northern Wisconsin, and in Minnesota, North Dakota, Iowa, and Montana. Both these varieties and those that are less winter-hardy have been reasonably satisfactory for seed production in the Willamette Valley and southwestward in Oregon. <P> Seed of new varieties intended for forage production in the North Central Region probably will be grown in one or more of these areas. Hence, breeders would like to know if seed potential measured at one geographic location where plant selection is practiced, will usefully predict actual seed yield at distant locations of commercial production. If so, then evaluation of the clones at breeding stations could be improved and simplified. Cooperators were available for such investigations in Oregon, North Dakota, Minnesota, Iowa, Missouri, and Illinois. Experiments were conducted at these locations to determine: (a) whether associations exist between seed production potential and morphological and physiological plant characteristics, and (b) if such associations are great enough to aid in selecting plants with both desirable forage and seed production potential. <P> </TD> <TD WIDTH="25%" VALIGN="TOP"> <B><FONT FACE="Arial">Table of Contents</FONT><P></B> <A HREF="page1.html">Review of Literature</A><BR> <A HREF="page2.html">Technical Description of Birdsfoot Trefoil</A><BR> <A HREF="page3.html">Materials and Methods</A><BR> <A HREF="page4.html">Results and Discussion</A><BR> <UL><LI><A HREF="page5.html">Morphological Characteristics</A> <LI><A HREF="page6.html">Simple Correlations</A> <LI><A HREF="page7.html">Stepwise Regression</A> </UL> <A HREF="page8.html">Summary</A><BR> <A HREF="page9.html">Literature Cited</A><BR> </TD> </TR> </TABLE> <P> <A HREF="./noframes/page2.html" TARGET="_top">[next]</A>
