Abb Grain Presents Capstan: A Very High Yielding, Cereal Eelworm Resistant, Dwarf Feed Barley.
Product/Service Name
Capstan
Applications very high yielding, cereal eelworm resistant, dwarf feed barley. Capstan is a mid to late maturing, very short strawed feed quality barley (tested as A WI 3385 ). Capstan has resistance and moderate tolerance to cereal cyst nematode (CCN). Capstan has very high grain yields and is targeted for high yielding, high input environments nominally over 400 mm annual rainfall.
Capstan has a small grain with moderate screenings and test weight and should be sown in areas with a mean annual rainfall above 400 mm to reduce risk of downgrade. Capstan has moderate resistance to net form of net blotch but is moderately susceptible to leaf scald, powdery mildew, leaf rust and the spot form of net blotch.
A Capstan has prostrate early growth and very short, stiff straw with excellent head retention. Capstan would be suitable for situations where harvest is delayed or where head loss risk is severe and windrowing is not a preferred option.
Sowing rates should achieve a minimum plant density 2 of 145 plants/m . Weight of grain sown should relate to seedbed conditions, germination % and grain weight which is generally similar to Schooner and lighter than Barque and Keel.
Capstan is being commercialised by ABB Grain Ltd and subject to an endpoint royalty.
Limited evidence (Hart, 2002) indicates that Capstan may have slightly reduced tolerance to herbicides such as Terbutryn and Achieve while reaction to other commonly used herbicides appears to be similar to other barley varieties. Experiments are continuing in this area.
Limited observations suggest that Capstan is intolerant of manganese deficient soils, like Skiff and Galleon. While further data is required, use of manganese enriched seed, nutrient seed coatings and manganese foliar sprays will still be necessary to reduce yield loss under stress conditions. Capstan is moderately intolerant of high soil boron, being similar to Keel and better than Galleon and Barque.
Capstan is well suited to May or June sowing relative to other varieties, and trials in recent years indicate that maximum potential yields occur when Capstan is sown in early June. No data is available for sowing
dates beyond June however the response from Capstan is expected to be similar to that of Gairdner and Skiff, being lower relative yields.
