“…Fiddian and Aldrich (1964) reported good correlations between field trials on eel worm-infested land and the susceptibility of artificially inoculated seedlings grown in pots in the glasshouse. Bingefors (1956) showed good correlation between progenies infected as seedlings and the same progenies infected as oneyear-old plants. It is anticipated that the test described here will give good predictions of the degree of resistance in the field.…”

summary A technique for selecting red clover seedlings for resistance to stem eelworm (Ditylenchus dipsaci) is described. This includes collection and drying of infected material, extraction of the eelworms, growing seedlings on vertical plates, and inoculation on filter paper. A method of assessment of the symptoms of infection after three weeks is described, and an example of results using this technique is quoted.

“…Preliminary studies had shown that swelling was very closely related to reproduction of nematodes in infected seedlings. This is the generally accepted definition of susceptibility in red clover (Bingefors 1957;Dijkstra 1957) and lucerne (Grundbacher 1962 Two factors which could have contributed to this result were investigated. They were:-(a) Nematode "race" (b) Seedling age at inoculation…”

A preliminary screening was made of many lines of white clover to find a line suited to New Zealand conditions, with resistance to the stem nematode (Ditylenchus dipsaci).A rapid screening technique developed for seedlings by Scandinavian workers was modified to give results which related to field resistance studies.The effects of inoculation varied with age of seedling, unsatisfactory results being obtained if plants were inoculated too soon after germination. Varieties differed in their relative susceptibilities to the white clover and red clover races of nematodes.Screening has revealed several lines relatively resistant to stem nematodes. and these have now to be tested for agronomic type. INTRODUCTIONThe varieties of Trifolium repens L. (white clover) in general use in New Zealand pastures have been found to be susceptible to infestation by the Ditylenchus dipsaci (Kuhn) Filipjev. stem nematode (Barclay and Williams, unpublished). In a spaced plant study a Ladino white clover and a variety of Moroccan origin possessed high resistance to such infestations, but both were considered to be too open in habit to be useful in New Zealand pastures. Furthermore, crosses made between these resistant types and those in general use produced hybrids which were often resistant to stem nematode but relatively open in habit (Barclay and Williams, unpublished).To make rapid progress in breeding agronomically desirable, nematode-resistant white clovers, many plants may need to be screened for resistance. The present study describes further suitable modifications to a laboratory screening technique devised and modified by Frandsen (1951), Bingefors (1957), Dijkstra (1956), Grundbacher (1962), and Hanna and Hawn (1956. Results of screening a wide range of white clover varieties and ecotypes with the modified technique are described.
