Abstract The clover cyst nematode (Heterodera trifolii) infects white clover (Trifolium repens) in pasture throughout New Zealand, reducing plant growth and nutrition. The preferred control method for both economic and ecological reasons is to breed resistant cultivars, with resistance measured as a reduction in cysts/g of root dry weight. Many New Zealand and overseas white clover seed lines and cultivars were screened for resistance. There were highly significant differences between lines for… Expand
Progress towards clover cyst nematode resistant white clover
The differences in numbers of cysts between resistant and susceptible lines increased during two generations of selection, supporting earlier results that indicated that progress in breeding for resistance was possible. Expand
Plant-parasitic nematodes on pasture in New Zealand
Progress made in white clover breeding programs in New Zealand is summarized and advances in genetic mapping and introgression as they affect resistance to nematodes are examined, together with observations which suggest that root-feeding nematode have little impact on yield and that the animal toxicity associated with Anguina seed galls in Australia is absent.

Achievements and Challenges in Improving Temperate Perennial Forage Legumes
This work expects genetic gain for yield and other complex traits to accelerate due to progress in genetic resource utilization, genomics resource development, integration of marker-assisted selection with breeding strategies, and trait engineering. Expand
Asymmetric competition between a hemiparasitic plant and a cyst nematode on a shared host plant
Competition between an animal parasite and a plant parasite for a shared host resource is demonstrated and is strongly asymmetric. Expand
Advances in pasture plant breeding for animal productivity and health
It is shown that Deleterious animal health and welfare effects can be alleviated through the use of non-toxic endophytes in grasses, that do not produce lolitrem B and ergovaline. Expand
Future options and targets for pasture plant breeding in New Zealand
It is predicted that some expansion of the species base of most pasture species is inadequate and requires continued effort to locate and import new materials from diverse international sources, and the development of a sustainable low‐input farming sector is predicted. Expand
Review: World checklist of white clover varieties II
Abstract The checklist presents a summary of information published since 1985 on the origin, breeding, and characteristics of white clover (Trifolium repens L.) varieties. This complements theExpand
The contribution of pasture research for animal production from legume-based pastures in temperate Australia
This series of papers reviews the literature and reflects on those characteristics of temperate pastures and their management that influence grazing value and sustainability and proposes that future research needs to broaden its scope to account for impacts on the soil, plant and livestock resources in the wider pastoral landscape.

Temperate Pastures for Grazing Livestock
This series of papers reviews the literature and reflects on those characteristics of temperate pastures and their management that influence grazing value and sustainability. In temperateExpand


Variation in white clover for root‐knot nematode resistance
While there were significant correlations between the re‐screens for galls, roots, and galls/root, the values showed that repeatability was low, and Comparisons with other nematode and clover species ... Expand
Laboratory screening of white clover for resistance to stem nematode
Screening of many lines of white clover revealed several lines relatively resistant to stem nematodes, and these have now to be tested for agronomic type. Expand
Screening of legume varieties for resistance to the root nematodes Heterodera trifolii and Meloidogyne hapla
Establishment of 15 lines of legumes on two soils with differing nematode populations was studied under greenhouse conditions, finding subterranean clover was tolerant to attack, but yield of red clovers was reduced by M. hapla. Expand
Selection for resistance and tolerance of white clover to root-knot (Meloidogyne hapla) and clover cyst (Heterodera trifolii) nematodes
Resistance to the clover cyst nematode (Heterodera trifolii Goffart) was increased over unselected controls but tolerance was not reliably assessed because the numbers of nematodes were too low. Expand
Reproduction of Meloidogyne Hapla and Heterodera Trifolii From Several Sites in New Zealand On Resistant and Susceptible Lines of White Clover
There was not a significant interaction between lines and populations for numbers of galls or egg masses, suggesting that the resistance to M. hapla may be horizontal and H. trifolii may be of the vertical type. Expand
The effect of root nematodes on the utilisation of phosphorus by white clover on a yellow-brown loam
The effects of the parasitic root nematodes Heterodera trifolii (clover cyst nematode) and Meloidogyne hapla (root-knot nematode) on the response of white clover to applied phosphorus on Egmont brownExpand
Effect of soil fumigation on white clover growth in a yellow-grey earth infested with clover cyst nematode
During periods of activity of the clover cyst nematode yields were up to 46% higher in fumigated than in control plots, and the effect was enhanced by moisture stress. Expand

A survey of root knot and clover cyst nematodes in dry hill country
Clover cyst nematode was found over most of the corresponding South Island hill country regions sampled, and the implication for white clover breeding programmes is discussed. Expand
Interrelationships between Root-nodule Bacteria, Plant-parasitic Nematodes and their Leguminous Host.
Both nematodes invaded the entire root system, uniformly showing preference for nodules, and the drastic reduction of the total-N in H. trifolii-infected plants reflected stunting of the entire plant due to nematode infection. Expand
