* Follows weekend launch of rival Apple Inc's iPad

BOSTON/HELSINKI, April 6 (Reuters) - The world's top cellphone maker, Nokia (NOK1V.HE), is working on its own Internet tablet, scheduled to reach stores later this year, a technology sector analyst said on Tuesday.

Over the weekend, rival Apple Inc (AAPL.O) sold more than 300,000 iPads on the tablet computer's first day in stores, a strong showing that roughly matched Wall Street forecasts and mirrored the iPhone's debut in 2007. [ID:nSGE6340DJ]

"Right now the supply chain [for a Nokia tablet] is being primed up for a fall release. It has to be on the shelf by September-October to meet demand for the holiday window," said Ashok Kumar, analyst with Rodman and Renshaw.

A spokesman for Nokia declined to comment. (Reporting by Jim Finkle in Boston and Tarmo Virki in Helsinki; editing by Simon Jessop)
