GRAINS-Wheat falls 1 pct, set to finish week higher on U.S. crop fears

* Wheat set to finish the week up nearly 1 pct

* Soybeans poised to close week up 3 pct

* Corn little changed, but set for third weekly gain

SYDNEY, April 13 (Reuters) - U.S. wheat futures fell nearly 1 percent on Friday as ample global supplies weighed on prices, although the grain remains underpinned by fears of crop losses across the United States and was poised to finish the week in positive territory. Soybeans edged higher as well, with the oilseed poised to finish the week up nearly 3 percent. Corn was set to finish the week only slightly higher. The most active wheat futures on the Chicago Board Of Trade fell 0.9 percent to $4.76-3/4 a bushel by 0453 GMT, having closed down 1.3 percent on Thursday. Wheat is up nearly 1 percent for the week, the second straight weekly gain. Analysts said wheat continues to come under pressure as ample global supplies depress demand for U.S. supplies. "U.S. export sales continue to be dismal given it has not been competitive outside its own backyard for quite some time," said Tobin Gorey, director of agricultural strategy at the Commonwealth Bank of Australia. The U.S. Department of Agriculture reported export sales for old and new crop U.S. wheat in the latest week at 188,700 tonnes, below trade expectations. The USDA on Tuesday raised its forecast of world wheat stocks at the end of the 2017/18 marketing year to 271.2 million tonnes, an all-time high. The most active soybean futures rose 0.3 percent to $10.64-1/4 a bushel, having firmed 1.2 percent on Thursday. Soybeans are up nearly 3 percent for the week, the biggest weekly gain in two months. The most active corn futures were little changed at $3.88-1/2 a bushel after closing up 0.4 percent on Thursday. Corn is up marginally for the week, the third straight weekly gain. The USDA reported export sales of old and new crop U.S. soybeans in the week to April 5 at 2,464,500 tonnes, topping a range of trade expectations. Sales of old-crop soybeans topped 1.5 million tonnes, the most in five weeks.
