“…Yields during this period were 36 and 31% higher for these cultivars, respectively, than the mean of the other cultivars. The early yield advantage of Moata recorded in this experiment agreed with other grazing and mowing experiments at Gore and Palmerston North (Armstrong 1981), farm evaluations in the Bay of Plenty (Percival et al 1989), and results from several cultivar evaluations throughout New Zealand (J.

“…Manawa behaves as a persistent Italian ryegrass if not continually hardgrazed (Lambert 1954;Brougham 1960;Forde et al 1988). The next major development was the breeding of tetraploid Italian ryegrasses, namely 'Grasslands Tama' derived from Westerwolds ryegrass (Barclay & Vartha 1967), and 'Grasslands Moata' derived from Paroa (Armstrong 1981), first certified in 1968 and 1980 respectively. These two cultivars are faster establishing and of higher quality than the earlier-bred diploids (Brookes & New Zealand Journal of Agricultural Research, 1994, Vol.…”

Three Italian and four hybrid ryegrass cultivars (Lolium multiflorum and L. boucheanum Syn. L. hybridum) sown with the white clover cultivar Grasslands Huia (Trifolium repens), were evaluated under frequent/hard grazing or infrequent/ lax grazing. Dry matter (DM) yields and species composition were assessed for 5½ years. Ryegrass tiller and white clover growing point population densities were determined annually, and leafrstem ratios every spring and autumn. Ryegrass tillers were assessed for infection with an Acremoniumlike endophytic fungus and bacterial wilt disease (Xanthomonas campestris pv. graminis). The Italian ryegrass cultivars Moata and Concord had total yields 33% greater than the mean of the other cultivars (1800 kg DM/ha) over the first autumn and winter. The Italian cultivars persisted well for 3 years, except Concord which had a high incidence (34%) of bacterial wilt. Of the hybrid ryegrasses, cultivar Corvette had high ryegrass yields in the first year (9800 kg DM/ha), similar to those of the Italian cultivars, and continued to be high-yielding and persistent throughout the experiment. However, its degree of aftermath heading was high and probably reduced ryegrass herbage quality in summer and autumn. An inverse relationship between ryegrass yield and white clover yield resulted in few significant differences in total yields between cultivars. Infrequent/lax grazing maximised total annual yields (+5%) but decreased white A94044 Received 21 April 1994; accepted 4 August 1994clover yields (-13%). With the importance placed on achieving high white clover growth in the cool temperate environment of Southland, choice of ryegrass cultivar should consider factors such as pasture quality (primarily percentage composition of white clover), tolerance of the cultivar to a range of grazing managements, and seasonal herbage production. The presence or absence of endophyte was not considered a major factor influencing the long-term persistence or productivity of the cultivars evaluated at this site.

“…Increased seedling growth was associated with increased seed size both between and within seed lots. Thus, not only could the cultivar quality be improved by rejecting low TSW seed lots from certification, but also by stricter dressing of seed lots to achieve a TSW of 4.5-5.0 g, the range originally described for the cultivar (Armstrong 1981 (Gerlach 1974). Under such conditions, small seed is unlikely to be able to compensate for inferior per plant performance.…”

“…This cultivar is noted for its rapid establishment and vigorous growth during winter and early spring. Armstrong (1981) considered that TSW for the cultivar ranged between 4.5 and 5.0 g and that this large seed would provide greater seedling vigour which would, in turn, promote better establishment. In the 1982-83 season, a 4.0 g TSW standard was introduced for Moata grown for certified seed production (Anon.…”

Effect of seed and seed lot 1000-seed weight on vegetative and reproductive yields of ‘Grasslands Moata’ tetraploid Italian ryegrass (Lolium multiflorum)

To cite this article: J. G. Hampton (1986) Abstract Increasing 1000-seed weight, both between and within seed lots of ' Grasslands Moata' tetraploid Italian ryegrass (Lotium multiflorum Lam.), increased seedling growth, emergence at 5 and 10°C, and vigour. When seed lots with 1000-seed weights of 3.2, 4.0, and 5.0 g respectively were sown at 15 kg ha-' , no significant differences in dry matter production were recorded, because the greater number of plants m-2 from the small seed lot compensated for reduced individual plant performance. When the same number of seeds (375 m-2 ) were sown for all three seed lots, dry matter production from the large seed was 32-42% greater than that from the small seeds through the winter and early spring. No differences in seed yield or yield components were recorded.
