Abstract:
... Perennial sorghum cropping offers substantial economic and ecological benefits, conserving fuel, water, and soil. To be perennial in temperate climates, a sorghum plant must over-winter and produce new growth the following spring—a trait derived from the weedy species Sorghum halepense. We have introduced perenniality from S. halepense into a S. bicolor background and identified QTL affecting eigh ...
