Resistance to Heterodera schachtii in patellares section of the genus Beta

Summary Fifty-two accessions of the section Patellares wild beet (including 26 Beta patellarisMoq., 13 B. procumbensChr. Sm and 13 B. webbianaMoq.) and 14 progeny families were selected and tested against sugarbeet cyst nematode, Heterodera schachtiiSchm. All Patellares species tested were highly resistant, but not immune, to the development of H. schachtii, after infection. This is the first report that mature female nematodes developed in the roots of B. webbiana plants. The occasional development of nematode cysts in roots of juvenile wild beets was, however, not a heritable genetic factor.Mention of a trademark, vendor, or proprietary product does not constitute a guarantee or warranty of the product by the USDA and does not imply its approval to the exclusion of other products or vendors that may also be suitable.
