1321089 potato Solanum tuberosum To ensure continuing worldwide availability of this valuable food staple, potato plant breeders must unite desirable processing and fresh-market characteristics with late blight resistance.
1322066 potato Solanum tuberosum Yes, Americans do love their spuds! We each eat about 125 pounds of them a year, about half from fresh potatoes and half in processed foods. Research has brought forth a slew of new, improved potato varieties for both uses. Take, for example, Atlantic-it makes potato chips with lower fat content than any other variety, thanks to its low ratio of water-to-solid-tissue. Atlantic is now the Nation's number one chipping potato. Are you one of the millions of Americans who never peels potatoes? Then perhaps you rely on our instant potato flakes. We invented the process in 1954 to help use up surplus potatoes. Our instant flakes were an instant hit and a big improvement over earlier powdered potatoes. Today, abut 400 million pounds of potato flakes are produced each year in the United States. Ever have a bag of potatoes go bad? Then you've probably met Phytophthora infestans, a fungus that can suddenly turn potatoes into a slimy, smelly mess. Over the years, this fungus, which affects potatoes in storage and in the field alike, has been controlled by chemicals. Lately, though, the microorganism has been showing a worrisome resistance. ARS scientists are developing new solutions to combat this old problem.

1322071 poinsettia Euphorbia pulcherrima Not only is poinsettia the most popular Christmas plant, it is the number-one flowering potted plant in the united states, even though its traditional sales period is just 6 weeks. That was not the case back in 1976, when ARS first began its program to improve the flower's dependability. This meant discovering the exact conditions of light and temperature the plant requires. they also performed breeding experiments that defined how color develops, and they devised precision growing methods that enabled massive cultivation. Last year, the wholesale value of the poinsettia crop reached nearly $170 million-a jump of more than 400 percent from 1976. The poinsettia, a contemporary symbol of Christmas, was introduced to the United States and named after Joel Robert Poinsett in 1825. Poinsett was serving as the first U.S. ambassador to Mexico when he saw the plant growing on the hillsides of southern Mexico, where the plant is native. The Aztec Indians prized poinsettias and considered them a symbol of purity because of their brilliant red color. They made a reddish-purple dye from the colored "flowers", which are actually modified leaves called bracts. They also made a medicine against fevers from the latex sap of the plant
1322065 orange Citrus x sinensis Sixty years ago, orange juice came either freshly squeezed in season or canned and tasting like the can. But in 1948, ARS scientists collaborated with Florida Citrus Commission researchers to perfect a method to produce a practical, flavorful frozen concentrate with all its vitamins and minerals.
