* Corn falls after 2-day rally, wheat hovers near 3-week top
* Slow maturity of U.S. corn crop seen delaying harvest
(Adds details, quotes) SINGAPORE, Sept 7 (Reuters) - Chicago corn futures slid on Thursday, giving up some of the recent gains that lifted the market to a two-week high in the last session on concerns over slow maturity of the U.S. crop. Wheat dipped following four sessions of gains, trading not far from Wednesday's near three-week high. The Chicago Board Of Trade most-active corn contract was down 0.7 percent to $3.58-1/2 a bushel by 0226 GMT after climbing in the previous session to $3.62 a bushel, the highest since Aug. 23. Wheat was down 0.2 percent to $4.45 a bushel and soybeans lost 0.1 percent to $9.70 a bushel. "U.S. Midwest weather is providing a sympathetic soundtrack to analysts cutting their U.S. (corn) yield forecasts," said Tobin Gorey, director of agricultural strategy, Commonwealth Bank of Australia. "The forecasts will be tested against the USDA's next crop report." Corn is drawing support from concerns about slow crop maturity that may delay the start of harvest and leave crops vulnerable to adverse weather. The U.S. Department of Agriculture in a weekly report late Tuesday said 12 percent of the U.S. corn crop was mature, behind the five-year average of 18 percent. Forecasts called for dry weather across much of the Midwest for the next 10 days, potentially stressing the maturing U.S. soybean crop. The expected arrival of hurricane Irma in the southeast of the United States next week could also hit some soybean and corn crops. Brazil is likely to offer stiff competition next year in the global soybean export market. Brazil is expected to export a record 65 million tonnes of soybeans in 2018 although the country's overall output may fall, industry group Abiove said on Wednesday in its first forecast for next season. For wheat, a virtually complete survey of France's soft wheat harvest this year confirmed high quality levels in the European Union's largest producer and exporter of the grain.
