PDF-[BOOK]-Hybrid: The History and Science of Plant Breeding

Disheartened by the shrinkwrapped Styrofoampacked state of contemporary supermarket fruits and vegetables many shoppers hark back to a more innocent time to visions of succulent red tomatoes plucked straight from the vine gleaming orange carrots pulled from loamy brown soil swirling heads of green lettuce basking in the sun With Hybrid Noel Kingsbury reveals that even those imaginary perfect foods are themselves far from anything that could properly be called natural rather they represent the end of a millennialong history of selective breeding and hybridization Starting his story at the birth of agriculture Kingsbury traces the history of human attempts to make plants more reliable productive and nutritiousa story that owes as much to accident and error as to innovation and experiment Drawing on historical and scientific accounts as well as a rich trove of anecdotes Kingsbury shows how scientists amateur breeders and countless anonymous farmers and gardeners slowly caused the evolutionary pressures of nature to be supplanted by those of human needsand thus led us from sparse wild grasses to succulent corn cobs and from mealy white wild carrots to the juicy vegetables we enjoy today At the same time Kingsbury reminds us that contemporary controversies over the Green Revolution and genetically modified crops are not new plant breeding has always had a political dimension A powerful reminder of the complicated and everevolving relationship between humans and the natural world Hybrid will give readers a thoughtful new perspective onand a renewed appreciation ofthe cereal crops vegetables fruits and flowers that are central to our way of life.
