Assessment of the resistance of potato varieties to common scab

  • R. K. McKee
Articles

Summary

Field and glasshouse methods of assessing the resistance of potato varieties to common scab were investigated and procedures which were found to give satisfactory results are described in detail. Estimates of resistance for individual varieties in the two environments were closely correlated.

Examination of a number of isolates ofStreptomyces scabies showed that these varied greatly in virulence but no evidence of physiological specialisation was found.

Zusammenfassung

Feld- und Gewächshausmethoden zur Feststellung der Resistenz von Kartoffelsorten gegen Schorf wurden untersucht. Verfahren, die zufriedenstellende Resultate ergaben, sind in Einzelheiten beschrieben. Die Schätzungen der Resistenz bei den einzelnen Sorten in den beiden Umgebungen standen in enger Wechselbezichung zu einander.

Die Prüfung einer Anzahl Absonderungen vonStreptomyces scabies ergab, dass diese in Virulenz stark variierten; aber es wurde kein Fall von physiologischer Spezialisierung gefunden.

Résumé

Des méthodes d'évaluation de la résistance à la gale commune de variétés de pommes de terre ont fait l'objet d'investigations en plein champ et en serre, alors que les modes opératoires donnant des résultats satisfaisants, ont été décrits en détail. Une corrélation étroite a été établie entre les estimations de la résistance pour chacune des variétés distinctes, placées dans les deux ambiances. L'examen de quelques cas isolés deStreptomyces scabies a démontré une grande variation dans la virulence sans qu'une preuve de spécialisation physiologique ne fút fournie.
