Russian Deputy Prime Minister Grigory Yavlinsky, co-author of the 500-day plan for a transition to a market economy, resigned in protest Wednesday because the central government is intent on implementing a more conservative plan.

The official Soviet news agency Tass said Yavlinsky announced his resignation to a joint session of the Russian Parliament, saying it is unrealistic to expect the 500-day program to be implemented when President Mikhail Gorbachev and the central government do not support it.Gorbachev, who had earlier voiced support for the 500-day plan, submitted a compromise proposal to Parliament committees Tuesday that maintains many of the conservative aspects and central controls from a rival plan favored by Premier Nikolai Ryzhkov.

The 500-day plan is a blueprint for a quicker, more radical move to a market economy. It was drafted by a commission set up by Gorbachev and Russian leader Boris Yeltsin, with economist Stanislav Shatalin and Yavlinsky its main co-authors.

Russia's Parliament has already approved the more radical plan, and many officials and economists say it would be impossible to form a workable blueprint by combining the two radically different rival plans.

On Tuesday Yeltsin warned if the compromise plan is adopted by the Soviet government, the Russian republic may be forced to ignore the Kremlin plan and implement the 500-day program - essentially splitting its economy from the Soviet Union.

The Associated Press reported incorrectly on Tuesday that a plan by Mikhail S. Gorbachev to rescue the Soviet economy included plans for interest-free loans to help people buy cars and computers. The plan did not include such provisions.
