New varieties added to grass and clover lists for England and Wales
Two white clover, one red clover, two Italian rye-grass, and eight perennial rye-grass varieties have been added to the Recommended Grass and Clover Lists (RGCL) for England and Wales 2025/26.
The new varieties have been granted provisional recommended status after they showed a clear improvement compared with the varieties already on the lists.
The varieties were added to the list yesterday (Tuesday, June 10), following over six years of independent and rigorous testing at trial sites across England and Wales.
The grass and clover varieties were assessed under a range of conditions, covering both conservation and simulated grazing management systems.
These provisionally recommended varieties will be reassessed after five years.
If they continue to perform well, they will be recommended for general use and reviewed every four years, until they are outclassed by other varieties.
Forage crop specialist at the National Institute of Agricultural Botany (NIAB), Ellie Roberts, who coordinates the RGCL trial programme on behalf of the British Society of Plant Breeders, said:
'The RGCL is a mechanism that challenges breeders to continue developing grass and clover varieties with increased forage yield potential, nutritional quality, and nitrogen use efficiency.'
'With input from seed merchants, the lists can help farmers identify the best varieties and variety mixtures for specific farming systems while considering growing conditions, animal nutritional requirements and economic efficiency.'
New grass and clover varieties
The new grass and clover varieties are as follows:
White clover varieties: Ruru; W140140;
Ruru; W140140; Red clover varieties: RGT Javva;
RGT Javva; Italian rye-grass varieties: Ascari (diploid); Glacomo (diploid).
Ascari (diploid); Glacomo (diploid). Intermediate perennial rye-grass varieties: Bartui (diploid); Castlewellan* (tetraploid).
Bartui (diploid); Castlewellan* (tetraploid). Late perennial rye-grass varieties: AberEsk (diploid); Angorat (diploid); Frogmore (diploid); Scartorp (diploid); AberLiffey (diploid); Ardress (tetraploid).
Unless stated, all varieties have been granted a provisional general use recommendation. Varieties marked with an asterisk (*) have been granted a provisional specific use recommendation.
Due to seed availability, not all new additions will be widely available initially.

‘Getting to grips with herbicide-resistant grass weeds a priority'
The challenge of herbicide-resistant grass weeds continues to grow on Irish tillage farms at an alarming rate. Meanwhile, the prospect of a significant decline in the availability of herbicide chemistries needed to deal with this problem becomes ever greater, according to Teagasc tillage specialist, Shay Phelan. Recent months have seen Blackgrass declared a noxious grass weed by the Irish government. But this is only the tip of a fast-growing iceberg. Glyphosate resistant Italian ryegrass populations have also recently been identified in Ireland for the first time. Phelan said: 'Getting to grips with herbicide resistant grass weeds within crops is a priority now. Growers can't afford to wait until next season and hope to use a chemical at that stage. 'Such an approach just won't work. The only way to tackle the issue is to ensure that mature seeds are not allowed to be produced this year. 'Options here include spraying areas of crops that have heavy weed infestations with glyphosate or hand rogueing, if feasible. But these jobs must be tackled now.' Crucial to all of this is farmers being able to identify the various weeds within crops at their various growth stages. Phelan explained: 'These critical grass weeds can produce large numbers of seeds that will reinfest your land if no action is taken. 'Control measures include marking weed patches, preventing seed return through hand rogueing or spot spraying, and, for severe infestations, whole cropping or spraying off. 'Delaying these measures until after seed set will lead to costly, long-term consequences.' Mature grass weeds are easier to spot when they are flowering or have visible seed heads. Herbicide-resistant grass weeds Teagasc has quantified the scale of the threat now posed to Irish tillage by herbicide-resistant grass weeds. Italian ryegrass represents an increasing threat with 81% of suspected populations confirmed resistant, necessitating zero-tolerance and strict biosecurity. The plant has flattened spike heads with awned spikelets on opposite sides of the stem. According to the Teagasc tillage specialist, Blackgrass is not present on every farm. However, cases are cases are rising. Resistance has been confirmed in 63% of suspected populations, necessitating a zero-tolerance and strict biosecurity on the part of growers. The plant has compact, slender spike heads with brown or purple-tinged awned spikelets. Spring wild oats is a common, competitive grass weed with loose panicle, large spikelets and bent awns. Herbicide resistance has been confirmed in 34% of suspected populations. Growers should hand-rogue herbicide escapees to prevent resistance development.

'Very topical' Leaving Cert Irish paper covers areas students would have expected
Irish paper 1 presented students with topics like AI and asked them to consider if Ireland is a good country to live in, as the Leaving Cert exams continued on Monday afternoon. The 2025 higher level Irish paper 1 covered key areas students would have expected, according to teacher Stephen Doyle, subject spokesperson with Studyclix. 'The aural section had clear recordings covering a good variety of topics," he said. However, while the questions were 'generally fair', some detailed questions in 'cuid c' required careful listening skills, he believed. 'The essay options gave students a wide range of current and relevant topics including people they admire, whether Ireland is a good place to live, environmental issues, and timely topics like world politics and current news stories." Students could also choose to write a story based on either 'dóchas', which means 'hope', or around the statement 'is ait an mac an saol' which means 'life is strange and wonderful'. Mr Doyle added: 'The exam was very topical and covered issues that students would be genuinely interested in, such as AI which was expected to appear, as well as global politics and whether Ireland is a good country to live in.' Ordinary level The ordinary level paper was also very accessible, he thought. 'The composition section offered simple choices including writing a blog on shopping, an interesting place or their favourite sports person. 'On the other hand, the vocabulary needed for section c, the letter, would have challenged any sixth year ordinary level student. "The story option would be welcomed by students as it allowed them to discuss music and a concert they attended. Overall, this was a manageable paper.' Leaving Cert exams continue on Tuesday with Irish paper 2 and biology, while Junior Cycle exams will continue with graphics, Italian and French.
