Relative resistance of potato varieties to serious mechanical injury

Misener, G.C.andTai,G.C.C.1993. Relativeresistance of potato varieties to serious mechanical injury. Can. Agric. Eng. 35:289291. The varietal susceptibility of potatoes to serious mechanical injury was investigated over a three-year period. Results from the study indicated a relativeconsistencyin terms of rankingfrom year to year of the varieties to their susceptibility to injury. The study suggested that proper selectionof varieties based on their suscepti bilityto injury can have a major impacton the quantityof seriously injured potatoes due to the harvesting operation. Nous avons etudie la susceptibilite aux dommages mecaniquesde plusieurs varietes de pomme de terre cultivees au Canada durant une periode de trois ans. Les resultats obtenus ont montre que le classement de ces varietes en termes de leur susceptibilite aux dommages mecaniques demeure relativement constant d'une annee a l'autre. Nos resultats semblent egalement indiquer qu'une selection appropriee des cultivars en fonction de cette susceptibilite aux dommages mecaniques peut resulter en d'importantes variations de quantites de pommes de terre serieusement endommagees par les equipements de
