GRAINS-Wheat eases after weather rally; corn, soybeans steady

* CBOT wheat eases after 1-year top driven by spring wheat

* Corn, soybeans firm after Friday lows on benign weather

* Focus turns to crop progress data, planting/stocks reports

(Updates with European trading, changes byline/dateline) PARIS/SYDNEY, June 26 (Reuters) - U.S. wheat prices fell on Monday, with Chicago futures retreating from a one-year high and spring wheat edging back from a 2-1/2 year top, as the market awaited more indications on crop conditions after adverse growing weather. Corn and soybeans ticked higher, consolidating after touching three-month and 15-month lows, respectively, on Friday when a favourable weather outlook in the U.S. Midwest encouraged selling. The most active wheat futures on the Chicago Board Of Trade fell 1.4 percent to $4.66-3/4 a bushel by 1054 GMT, pulling away from Friday's high of $4.80-1/2 a bushel, a level last reached in June 2016. Minneapolis spring wheat futures, which have led the recent rally in wheat markets, jumped 2 percent to $6.75 a bushel, a new high since December 2014, before pulling back to trade marginally lower on the day. An advancing U.S. winter wheat harvest and a break in a heatwave in western Europe encouraged wheat futures to ease while traders await a weekly U.S. government crop report after the U.S. market close on Monday. The previous U.S. Department of Agriculture (USDA) report fuelled the run-up in prices by showing an unexpected drop in spring wheat ratings despite the return of rain in the parched northern U.S. Plains. Poor conditions for spring wheat has heightened concern about limited high-protein supplies this year after early results from the hard red winter wheat harvest showed lower than normal protein content. "The wheat price in Chicago has fallen (...) as part of a consolidation process following a steep rise," Commerzbank analysts said in a note. "The fundamental justification for higher wheat prices remains, however: the heatwave that has many of the world's leading growing regions in its grip, including parts of the U.S. Great Plains and the EU." Wheat markets are also waiting for a clearer picture of potential crop damage from a heatwave last week that baked French wheat crops already enduring dry conditions. The most active CBOT corn futures rose 0.5 percent to $3.59-1/2 a bushel, stabilising after a slide on Friday when prices hit their lowest since March 31 at $3.56-1/2 a bushel. The most active soybean futures added 0.4 percent to $9.08-1/2 a bushel, holding above the $9 psychological threshold after setting a near 15-month low at $9.00-1/4 on Friday. Corn and soybeans are under pressure from forecasts for largely benign weather across key U.S. growing regions, analysts said. Market attention is also turning towards this Friday's USDA quarterly U.S. grain stocks report and update planting estimates, publications that can trigger sharp price movements.
