Abstract

A new rating scale is given which enables more reliable and accurate greenhouse and field assessment of damage by rootknot and reniform nematodes on their host crops. It is based mainly on number of egg masses per plant, reproduction factor, and different levels of statistical probabilities. It should be of use both to nematologists and plant breeders. Other rating schemes have been reviewed.

Keywords

Zusammenfassung

Es wird eine Bewertungs-Skala vorgestellt, die im Glashaus und Freiland eine zuverlässigere und genauere Einschätzung der Schädlichkeit von Wurzelknollen- und Reniform-Nematoden bei ihren Wirtspflanzen ermöglicht. Sie basiert hauptsächlich auf der Zahl der Eimassen pro Pflanze, deren Reproduktionsfaktor sowie verschiedener Grenzwerte der statistischen Wahrscheinlichkeit. Sie sollte sowohl von Nematodologen als auch von Pflanzenzüchtern angewandt werden. Andere Bewertungssysteme werden erörtert.
