* India rates rise to $537 - $546 per ton
* Higher prices dent demand for Thai variety - trader
* Indian curbs to propel Pakistan's rice exports
Feb 1 (Reuters) - Parboiled rice export prices from India extended their record rally this week, driven by tight supplies and firm demand due to higher prices in other hubs, while Thai rates slipped as new supply from fresh harvests trickled in.

"Indian prices are rising, but they still trade at a steep discount compared to supplies from Pakistan and Thailand. This discount is helping to maintain demand," said a Mumbai-based dealer with a global trade house.
Pakistan's rice exports are likely to jump to a record high in the year ending in June as rival India's decision to curb shipments forces buyers to turn to Islamabad, which is selling the grain at nearly 16-year high prices.
Thailand's 5% broken rice prices
Prices dropped as new crops were rapidly coming out, one Bangkok-based trader said, but added that Thai rice was not winning at auctions due to high prices.
Another trade said Vietnamese rice won bids to Pakistan and Indonesia.

"Price edged up after Vietnamese exporters were selected to supply most of the 500,000 tons in Indonesian Bulog's latest tender," a trader based in Ho Chi Minh City said.
Prices also found support from Vietnam and the Philippines memorandum of understanding on rice trade that was signed earlier this week, the trader added.
Meanwhile, Bangladesh will allow rice imports by reducing duties if necessary to reduce the price of the country's main food grain, Food Minister Sadhan Chandra Majumdar said.
