The flowering time of present narrow-leafed lupin varieties is now probably correct for most of Western Australia's grain growing areas. However lupin yields are frequently not as high as might be expected, in either low or high yielding sistuations, and further marked yield improvements seem theoretically possible. A likely reason for seed yields being below expectations is the growth and development pattern of present lupin varieties.
Some new lupin types in which branching is suppressed genetically - known as reduced-branching types - are being studied. These types could be useful in some lupin growing areas to help overcome seed yield problems.
