Grandi is the tallest of the three most recent varieties developed by HGI. Similar in seed size to CFX-1, this variety was developed as a grain variety for regions further south. Key characteristics of the plant include excellent harvestability on a slightly taller plant frame.


Growers operating on dryland systems in the southern part of Canada and mid to northern regions of the USA find that grain yields are strong thanks to a larger seed size and uniform plant structure.
