The sales comprised 259 tonnes of the Giza 88 variety, 22 tonnes of Giza 90 and 234 tonnes of Giza 86, the official said.

Alcotexa's export commitments for the 2010/11 season, which began in September, are now 89,870 tonnes of cotton worth $334.966 million, the official added.

By this time last year, Alcotexa had sold 50,700 tonnes of cotton worth $112.24 million.
