“…Variation in weather conditions affecting the success of pollination also has a great effect on seed yield (Savatti, ). Tetraploid red clover frequently produces lower seed yield than diploid red clover due to lower fertility and also because it has longer corolla tubes causing pollination problems (Mackiewicz, ; Anderson, ). However, in this investigation, low seed yields were found in both cultivars (Table ).…”

The effect of boron (B) on flower development, nectar production, seed yield and germination in organic red clover was investigated in soils with <1 mg B kg−1. Different techniques for application of a liquid B product were studied in four field experiments in 2009–2011. The treatments were as follows: control (no B); three rates of B application to the soil at sowing; and three rates of B as foliar application in the harvest year. The effects of B application varied between the fields and included increased seed yield, seed weight of fifty inflorescences (IFs), number of florets IF−1 and nectar volume IF−1. The greatest effects on seed yield were found in treatments with low B rates. Boron application increased seed B concentration in only one experiment and had no effect on shoot B concentration. The percentage of seeds with normal germination increased with increasing seed B concentration (R2 = 0·73). Seed weight of fifty IFs and number of IFs m−2 increased with increasing shoot B concentration. Boron is therefore an important element for red clover seed production. Further knowledge on improving the B uptake of red clover plants is required to improve seed yield and quality.

“…'Turoa' was a specific selection for persistence under close grazing. The tetraploid variety 'Pawera' is a more recent release with improved persistence and resistance to insects and fungi conferred by phytoestrogens (Anderson 1973;Sutherland et al 1980). Concerns about these oestrogenic compounds' impact on reproductive efficiency in ewes grazing red clover monocultures led to selection of new varieties with low and moderate levels of phytoestrogens.…”

Red clover (Trifolium pratense L.) offers a number of advantages as a forage legume, but is constrained by poor persistence under grazing. The objective of this research was to test the growth and persistence of 18 populations among a wider set of 142 New Zealand and overseas accessions of red clover, in a mixed-sward replicated plot trial under rotational grazing by cattle in the Manawatu. We also measured plant morphological trait expression in a row trial using samples of the same red clover populations evaluated in the plot trial. Most red clover populations showed a marked decline in growth score after two years under grazing. The new variety 'Grasslands Relish' showed significantly (P

“…However, the release of the new cultivar 'Grasslands Pawera' red clover (Anderson 1973) caused some concern, as this cultivar was more productive and persistent than earlier red clovers, had relatively high levels of leaf formononetin, and showed oestrogenic activity to sheep (Kelly et al 1979). Accordingly, it was decided to breed a low-formononetin version of Pawera.…”

Stupefying and lethal effects of alpha chloralose in chickens

'Grasslands G27' red clover was bred from the tetraploid cultivar 'Grasslands Pawera', with selection aimed at reducing the concentration of the isoflavone, formononetin. Selection proceeded for seven generations and resulted in the formononetin level being less than half of that in Pawera under sward conditions. This reduction increases ewe ovulation, conception, and lambing rates by a significant amount.Other characteristics of G27, probably a consequence of reduced formononetin level, are increased palatability and reduced disease tolerance. Since both of these characters would tend to reduce sward persistence, G27 was selected also for increased shoot density and prostrateness to help counteract these weaknesses.
