Wild Plants to the Rescue
Efforts to domesticate new, high-yield, perennial grain crops require patience and persistence—but such plants could transform agriculture
Efforts to breed perennial grains are not new, nor are the methods best suited to the work. David Van Tassel and Lee DeHaan work on programs at the nonprofit Land Institute in Salina, Kansas, and are making slow but sure progress in breeding perennial sunflower crops as well as a perennial similar to wheat. The authors discuss the methods they employ in this work; the challenges of long-term research projects; and potential candidates for additional perennial grain crops.
