Forage Quality Of Alfalfa Protected By Resistance To Bacterial Leaf Spot, Andrew W. Lenssen, E. L. Sorensen, G. L. Posler, D. L. Stuteville

Bacterial leaf spot (BLS), caused by Xanthomonas campestris pv. arfalfae Dye (Xca ), can prevent stand establishment and decrease the yield and persistence of alfalfa (Medicago sativa L.) in the central USA. Previous studies have shown that BLS inoculation may affect concentrations of monophenolic compounds and thus alter the forage quality of alfalfa. In a controlled environment, comparisons were made of forage quality, including phenolic monomers, of alfalfa cv. Kanza (susceptible) and KS76 germplasm (derived from Kanza, resistant) with and without inoculation with Xca. The cultivarx inoculation interactions were non-significant (P> 0.05 ) for all parameters determined for leaves and …
