- Highest dry rot tolerance of all commercially available swedes
- High yielding, main crop swede
- Bred and trialed by Plant & Food Research for NZ grazing systems
- Excellent keeping qualities with high bulb percentage
- White-fleshed with medium maturity
Keystone is a high yielding white-fleshed swede, that offers high quality feed that can be fed throughout winter to all main stock classes.
Agronomic Summary
Keystone has been released following extensive trialling by Plant & Food Research, PGG Wrightson Seeds Research and a MAF funded Sustainable Farming Fund (SFF) project looking into dry rot prevention in swedes.
The main outcome being that the dry matter yield of Keystone is comparable to other leading white fleshed swedes including Highlander and Winton, but with a higher level of dry rot tolerance than any other commercially available swede.
Dry Matter Yield
Average dry matter production (t DM / ha) of swede cultivars from a two year trial at Winton, Southland (2006-2008). * Indicates one year's results only.
