'Evangeline' sweetpotato.

摘要

Evangeline, a new sweet potato cultivar, was developed in Louisiana, USA, to provide a cultivar with characteristics similar to those of cv. Beauregard but with southern root-knot nematode resistance and higher sucrose content. It produces acceptable number of uniform plants (sprouts) comparable to Beauregard. Days to harvest for Evangeline and Beauregard are similar; however, Evangeline tends to produce fewer oversized or jumbo grade roots. Evangeline appears widely adapted and particularly valuable in soils infested with southern root-knot nematode. In addition, Evangeline is intermediate to resistant for soil rot caused by Streptomyces ipomoeae.
