“…However, there are many other forage species that fit minor ecological niches across New Zealand adding to resilience of pastures. These include annual legumes (Monk et al 2016) and lotus species (Bologna et al 1996) but for most of these there has been little recent breeding activity.…”

Plant breeding has had, and continues to have, an important role in providing farmers with resilient pastures. Early breeding relied on improvement of ecotype populations and this was accelerated by crossing with selected introduced germplasm. The primary traits under selection have targeted speed of establishment, total and/or seasonal dry matter (DM) yield, nutritive value or feed quality, flowering time and reduced aftermath heading, disease resistance, persistence and seed yield. Continued improvement through plant breeding to meet environmental concerns and tolerances to both biotic and abiotic stresses will be achieved through ongoing plant introductions, exploiting heterosis, speed breeding, genomic selection, improvements in phenotyping, metabolomics, improved compatibility with beneficial microbes, and potentially the use of transgenic and gene editing technologies.

Legumes have underpinned transformational change on New Zealand sheep and beef farms over the last 30 years. This was through an emphasis on ewe nutrition based on lucerne or red clover dominant pastures, and increased use of subterranean and white clovers on uncultivatable hill country. Pre- and post-weaning lamb growth rates have increased, and enabled earlier slaughter of heavier lambs. The farm systems results include greater numbers of hoggets mated, higher lambing percentages and greater ewe efficiency (kg lamb weaned/kg ewe mated). Extension packages to support legume use have compared growth rates of resident and legume-based pastures, economic analyses of successful farms and management packages for the most appropriate legume in different environments. Over the same period, the dairy industry rapidly expanded in cow numbers and area onto flat irrigated land on the Canterbury Plains. The nitrogen deficiency of perennial ryegrass was overcome by a linear increase in nitrogen fertiliser use. Environmental concerns from this intensification has led to a legislated nitrogen cap of 190 kg/ha.year. This, coupled with a recent trebling in urea price, has returned attention to increasing the white clover content of these pastures. Nitrogen applications can be minimised by using diverse pastures sown with a legume, herb and <8 kg/ha of perennial ryegrass. Work on other legumes, including annuals and those with condensed tannins, has to date failed to increase their use in most pastoral settings, with the exception of the perennial lupin which is adapted to high-aluminium soils in the South Island High Country.

“…Subterranean clover (Trifolium subterraneum) is an winter annual that has been promoted as a dryland pasture legume to provide late winter-early spring feed before perennial white clover and lucerne increase their growth in spring (Brown et al 2006). Subterranean clover is the most widely sown annual clover in New Zealand pastoral systems (Monk et al 2016). However, the commercial cultivars available are imported from Australia and local information is required to estimate initial seed yield which contributes to its persistence in New Zealand dryland areas.…”

At Lincoln University, Canterbury, seven subterranean cultivars rated in Australia as having different levels of ‘hardseedeness’ were established. Monocultures were sown in autumn and allowed to grow and set seed. Seed yields ranged from 340 to 1050 kg/ha. Heavy rain in early January 2016 resulted in a “false strike” of ≤ 4.0% of seeds during the subsequent dry February. A second emergence event in March also resulted in a “false strike” with a further 7 to 15% of total seeds lost. However, cultivars established >1000 seedlings/m2 after early winter rain, which is considered adequate for future persistence. Emergence was consistent with Australian hardseededness rankings. Cultivars with hardseed ranks <4 may be more suitable for dryland systems in New Zealand due to their early emergence and the ability to exploit the late summer and autumn rains.
