Stan this is what I meant by breeding for 'perennial habit'. These are not 'dreamers' doing the research. In real life, some farmer/ranchers in low-rainfall areas or areas with thin topsoil have saved their operations by planting perennial grasses on land formerly used for annual crops. Perennial legumes are often used to rebuild soil fertility, and water retention structures for livestock sometimes follow. Good for the landowners and good for us with the urge to hunt.
