Interpretive Summary: Austrian winter peas are an important crop in the high rainfall regions of eastern Washington and northern Idaho where they are grown in rotation with winter wheat. Commonly grown varieties have weak stems that lodge and cause seed rotting and reduced yields and quality. In this development, we incorporated the semi-leafless trait that converts the leaflets to additional tendrils that intertwine with adjacent leaves to form a dense upright canopy that resists lodging. The development has improved yields and quality of the crop. Other benefits of the upright canopy include avoidance of foliar diseases, better utilization of light for photosynthesis and overall yield increases. The variety is expected to become the predominant type in the region in the near future.

Technical Abstract: 'Granger' Austrian winter pea was developed for it's excellent winter- hardiness and resistance to lodging. Granger is a semi-leafless type that originated as an F5 selection (from a cross made in 1985. Winter survival in 1990 and 1991 equaled or exceeded that of 'Fenn' and 'Melrose'. Yields of Granger exceeded that of these two checks by 400 and 500 kg/ha, respectively from 1989 to 1994. Granger is resistant to fusarium wilt race 1, the predominant race in the region. Granger is named after the Grangeville region in Idaho, the predominant Austrian winter pea production area in the U.S. Small quantities of seed are available on request.
