KWS Launches Four New Forage Maize Varieties

Plant breeder, KWS, has launched four, new-generation maize hybrid forage and energy varieties, which are available for 2018 planting.

The first is KWS Calvini, an early forage variety with an FAO of 160-170. It has been selected for its very high starch and ME value, making it ideal for boosting dairy cow ration performance. KWS Calvini had the top dry matter yield in its class across all NIAB trials, producing 18.8 tonnes/ha. It has tremendous early vigour, with a high kernel content and excellent stability of ripening.


The second new variety is the dual-purpose Keops, which has an FAO of 210/220 and falls into the early/maincrop category. Suitable for either forage or energy uses, it has superb early vigour and an extremely high yield potential of 50-55 freshweight tonnes/ha. Its maincrop maturity position makes it ideal for spreading harvest window and the high grain to stover ratio provides stable ripening in cooler seasons, although it is generally recommended for warmer areas of the country.

The mid-season maturity variety, Amaveritas, FAO 240, had the distinction of being number one for dry matter yield for two consecutive years across the whole of the KWS Northern European trials network. It produces top yields for biogas, with figures of 55-60 tonnes/ha being recorded. Considered ideal for spreading harvest or drilling window on lighter land, it surpasses former generation hybrids, including Ronaldinio, Barros and Carolinio. Amaveritas also offers exceptional early vigour.

The fourth new variety in the KWS 2018 portfolio is Kilomeris, which is intended exclusively for biogas, offering a very high tonnage potential on light soils, where yields have been found to exceed its competitors, particularly in drought-prone areas. Other features include very good early vigour and tremendous stay-green qualities. Kilomeris, which is suitable for favourable sites, has an FAO of 260/270; this makes it KWS’ latest maturity hybrid in the UK market.

KWS maize sales manager, John Morgan says:
“Maize breeding continues to move forward and newer varieties offer significant advantages in terms of early maturity, yield and feed value. Holding on to older varieties for too long will undoubtedly mean losing out on potential forage improvements.”
