Abstract Selections of white clover resistant or susceptible to Heterodera trifolii in earlier rounds of a recurrent selection programme were intercrossed and selected in three further rounds of selection. Resistance and susceptibility were measured by comparisons of cysts per gram of root dry weight (cpg). In the third, fourth, and fifth rounds of recurrent selection, the mean cpg of progenies from resistant parents was 23% (n = 974), 6% (n = 870) and 11% (n = 98) of that of progenies from susceptible parents. In each selection round, the resistant selections had 31, 4 and 7% of the number of cysts on susceptible selections. The percentages of immune plants (i.e. with 0 cysts) in the resistant groups were 1, 39, and 50% after the third, fourth, and fifth rounds of recurrent selection, respectively. Inoculum from 16 populations of H. trifolii from around New Zealand was added to two resistant and two susceptible white clover lines. After one generation of nematode development there were fewer cysts on the resistant lines for each population tested. Two resistant and two susceptible lines were compared in a glasshouse trial for their reaction to parasitism by H. trifolii . Infection reduced the shoot weight of all four lines but resistant lines grew better than either one or both susceptible lines at 109, 126, and 160 days after inoculation. In contrast, the uninfected lines did not differ in shoot weight over five samplings. More cysts were recovered from susceptible lines (means of 370 and 430 cysts per plant) than from resistant lines (means of 41 and 56 cysts per plant). Results indicate that development of a white clover cultivar resistant to H. trifolii is achievable and that the resistance will be effective against the nematode in most of New Zealand. The growth study indicated that advantages will be conferred in pastures where the presence of H. trifolii causes major limitations to white clover growth and persistence. Zusammenfassung- Die Wirksamkeit einer mehrfach wiederholten Selektion von Weissklee (Trifolium repens) auf Resistenz gegen das Kleezystenalchen (Heterodera trifolii)- In einem fruheren Selektionsprogramm gegen Heterodera trifolii resistente oder anfallige Weisskleeselektionen wurden gekreuzt und in weiteren Selektionsrunden selektiert. Resistenz und Anfalligkeit wurden durch Vergleich der Anzahl der Zysten je Gramm Wurzeltrockengewicht (cpg) bestimmt. In der dritten, vierten und funften Runde der Wiederholungsselektion betrugen die cpg-Werte bei Nachkommen von resistenten Eltern 23% (n = 974), 6% (n = 870) und 11% (n = 98) der Werte bei Nachkommen anfalliger Eltern. In jeder der Selektionsrunden hatten die resistenten Selektionen nur 31, 4 und 7% der Zystenzahlen an den anfalligen Selektionen. Nach der dritten, vierten bzw. funften Selektionsrunde betrugen die Anteile immuner Pflanzen (d.h. mit 0 Zysten) 1, 39 bzw. 50%. Das Inoculum von 16 Populationen aus ganz Neuseeland wurde an zwei resistente und zwei anfallige Weisskleelinien gegeben. Nach einer Generation der Nematodenentwicklung waren an den resistenten Linien bei jeder der untersuchten Populationen weniger Zysten. Die Reaktion von zwei resistenten und zwei anfalligen Linien auf einen Befall mit H. trifolii wurde in einem Gewachshausversuch gepruft. Der Befall verringerte das Sprossgewicht aller vier Linien, doch wuchsen die resistenten Linien nach 109, 126 und 160 Tagen besser als die beiden anfalligen Linien. Im Gegensatz dazu unterschieden sich die Linien bei Nichtbefall bei funf Probenahmen im Sprossgewicht nicht voneinander. An den anfalligen Pflanzen wurden mehr Zysten gefunden (im Mittel 370 und 430 je Pflanze) als an den resistenten Pflanzen (im Mittel 41 und 56 je Pflanze). Die Ergebnisse zeigen, dass die Entwicklung einer gegen H. trifolii resistenten Weisskleesorte erreichbar ist, und dass diese Resistenz gegen die Nematoden im grossten Teil Neuseelands wirksam sein wird. Die Wachstumsuntersuchungen haben gezeigt, dass die Vorteile besonders auf solchen Weideflachen deutlich werden, wo die Anwesenheit von H. trifolii erhebliche Einschrankungen des Wachstums und des Uberdauerns von Weissklee verursacht.

The effects of temperature (constant 3, 6, 9, 12 and 24�C, and an alternating 6/12�C temperature regime), sowing depth (0, 15, 30 and 45 mm), and soil bulk density (1.1 and 1.3 g cm-3) were examined on the emergence of tall fescue (Festuca arundinacea, cv. Demeter) and white clover (Trifolium repens, cv. Haifa) in a factorial experiment, in controlled temperature cabinets. Mitscherlich curves were fitted to the emergence data and treatment effects on the maximum emergence percentage (A), rate of emergence (K) and time to first emergence (To), were statistically analysed. Temperature was the major factor affecting the fescue A value. The A value was low at 3 and 6�C, but increased as temperature increased to 12�C. It was depressed by the 45 mm sowing depth and by high bulk density at 30 and 45 mm. For white clover, sowing depth had a strong effect on A. Over all temperatures, A was high for surface sowing and low for deeper sowing (30 and 45 mm). For shallow sowing (15 mm), A was intermediate and increased with rising temperature. High bulk density depressed A at 15 mm. For both species, To increased as sowing depth increased, and decreased as temperature increased. The effect of sowing depth was more apparent at low temperatures. The K value for fescue increased gradually as temperature increased, but sowing depth had no effect. For clover, K increased markedly with rises in temperature for surface sowing, with smaller increases for 15, 30 and 45 mm depths. The 6/12�C regime responses for A and To were similar to the constant 12�C, while the K response was similar to the constant 9�C; these trends were similar for fescue and clover. It was concluded that establishment failures from direct drilling tall fescue on the Northern Tablelands can be related to low soil temperatures in winter (below 9�C), and for white clover, to excessive sowing depth (greater than 15 mm), particularly on high bulk density soils.

Four white clover cultivars 'Grasslands tluia', 'Grasslands Tahora', 'Grasslands Kopu' and 'Grasslands Pit& were evaluated at Grasslands Division, Gore, for 4 years, under 2 grazing managements. Year round rotational grazing was compared with rotational grazing incorporating a 1 P-week period of set stocking during spring. Huia was the best cultivar under both grazing managements. Tahora yields were comparable with those of Huia in spring and summer, and ryegrass yields were best in Tahora wards. The larger leaved and less stoloniferous Kopu and Pitau were not suited to the climatic conditions or the mtensive sheep grazing practices of the region.

White clover populations from Europe and New Zealand together with ecotypes collected from old pastures in Southland-Otago were evaluated as spaced plants at Gore. Plants were screened for herbage production and morphological and flowering characteristics. The Southland ecotypes and North Island hill country material are adapted to active growth in spring and summer. Their dense growth habit ensures continued production of branched stolons from nodal meristems which is necessary for high clover yield and persistence under intensive sheep grazing. In this region flowering characteristics are unimportant in relation to agronomic performance. Some largerleaved Huia and French lines have high-yielding features which are evident during autumn under lenient grazing. Hybrids between superior plants showing adaptive and high yie!ding features are being screened in order to select new types with the desired characteristics.

The nutritional benefits of condensed tannin (CT) in forages such as Lotus are known but difficulties with establishment, herbage production and persistence in a pasture have hindered farmer uptake of this valuable legume. A sheep grazing experiment was established to investigate the effects of growing three Lotus corniculatus (Grasslands Goldie, G46 and Creeping) and two L. pedunculatus (Grasslands Maku and Grasslands Trojan) cultivars with or without Grasslands Advance tall fescue (Schedonorus phoenix syn. Festuca arundinacea) and with or without white clover (Trifolium repens) under infrequent (8-weekly) grazing. Without grass, the content of L. corniculatus and L. pedunculatus in the swards was 85% and 60% respectively by year 3. Adding white clover reduced the Lotus content in the swards by 20%. With tall fescue, the L. corniculatus cultivars increased from 6 to 34% between the summer of year 2 and year 3. In contrast, the L. pedunculatus cultivars remained at very low 1- 2% levels in the summer of both years. Inclusion of white clover did not further reduce Lotus content in the tall fescue swards. While there was no significant difference in content and yield between L. corniculatus cultivars, there was a consistent trend for Goldie to produce more herbage. Goldie had the potential to produce 2 t dry matter (DM)/ ha/year in a mixed pasture with tall fescue under infrequent grazing. Creeping L. corniculatus contained higher CT levels than Goldie (3.5 cf.1.1% of herbage DM respectively) and is thus potentially able to provide greater amounts of CT in a pasture. Trojan and Maku L. pedunculatus had similar plant density and herbage productivity. The experiment will be monitored further to determine the long-term persistence of these Lotus cultivars in a mixed pasture.

An investigation was made during 1988 to test the hypothesis that ‘Grasslands Huia’ white clover (Trifolium repens L.) could be eliminated under close sheep grazing. The effects of grazing management, topography and fertilizer on the contribution of Huia plants to the white clover population in an 85 ha experimental upland pasture ecosystem in the southern North Island, New Zealand (lat. 40° 20′ S, long. 175° 50′ E, 125–350 m altitude) were quantified 11 years after oversowing. Replicated sampling sites (108 in total) were located on nine combinations of slope and aspect within grazing management treatments comprising rotational grazing with cattle (RC), rotational grazing with sheep (RS) and continuous grazing with sheep (CS), with high and low fertilizer treatments in each case. White clover occurrence, leaf area, phosphoglucoisomerase-2 (PGI-2) allele frequencies and the proportion of Grasslands Huia plants in the white clover population were determined at each site. White clover frequency was lower on steeper slopes. Aspect, slope and grazing management affected area of individual clover leaves. The proportion of Huia plants in the white clover population averaged 54·9, 49·0 and 33·6% for RC, RS and CS, respectively (P < 0·039, 5 D.F.). Fertilizer and topography did not affect the proportion of Huia. It was concluded that although Huia did persist after 11 years of close sheep grazing, its contribution to the total white clover population was unsatisfactory in some cases, and use of better adapted cultivars is suggested.

Sheep Production

Effects of tall fescue cultivar ('Advance' and 'Flecha') and clover species (white and subterranean (sub) clovers) combinations on pasture dry matter (DM) and sheep production were assessed in years four (2011/12), five (2012/13) and six (2013/14) after establishment in dryland, Canterbury. 'Advance' pastures yielded less total herbage than 'Flecha' pastures (13.9 cf. 16.5 t DM/ha) but more fescue (8.6 cf. 5.9 t DM/ha) and 2.1 t DM/ha clover in year four, 13.5 t DM/ha total herbage with more fescue (8.0 cf. 4.1 t DM/ha) and 1.9 t DM/ha clover in year five, and 11.7 t DM/ha total herbage, 5.4 t DM/ha fescue and 0.8 t DM/ha clover in year six. Sub clover pastures yielded more total, fescue and clover herbage (16.9, 8.8 and 3.2 t DM/ha) than white clover pastures (13.5, 5.7 and 1.0 t DM/ha) in year four, more fescue in year five (7.2 cf. 4.9 t DM/ha), and more clover in year six (1.2 cf. 0.3 t DM/ha). Sheep liveweight gain was greater for sub than white clover pastures in year four (939 cf. 431 kg/ha) and five (697 cf. 481 kg/ha) and 689 kg/ha in year six. Therefore, sub clover and 'Advance' were generally more productive than white clover and 'Flecha', but both fescues showed similar persistence after 6 years.

Assessment of the relative performance of white clover (Trifolium repens L.) cultivars, using multi-year and multi-location seasonal growth trials, is key to identification of material with specific and broad adaptation. This paper is based on a multi-year and multi-location study of 56 white clover entries comprising 14 commercial cultivars and 42 experimental synthetic lines evaluated for seasonal growth under rotational grazing across four locations in New Zealand over 4years. The four locations (and animals grazing) were: Kerikeri (beef cattle), Aorangi (beef cattle), Ruakura (dairy cattle), Lincoln (sheep). Significant (P&lt;0.05) genotypic variation among the 56 entries, and genotype × year, genotype× location and genotype× season interactions, were estimated. We were able to identify cultivars and experimental synthetics with specific and broad adaptation to the three grazing management types. Cvv. AberDance, Apex, Demand, Prestige, Quartz and Riesling, with leaf size ranging from small to medium–large, showed highly above-average performance under sheep grazing. Synthetic lines 15 and 45 also had highly above-average performance under sheep grazing. Cvv. Legacy and Kopu II showed above-average performance under cattle and dairy grazing. Synthetics 15, 48, 49, 44, 22 and 18 and cv. Quartz had above-average performance under all three grazing managements. Synthetics 27, 33 and 38 had highly above-average performance across all three grazing managements and were superior to all 14 cultivars evaluated. Several of these superior synthetics are being tested across multiple grazing environments. Among the 14 cultivars evaluated, Legacy and Quartz showed superior seasonal growth performance across the three grazing managements. Quartz is being evaluated in several on-farm trials across temperate regions of the world.
