TORONTO, July 25 (Reuters) - The Toronto Stock Exchange's main index rose 1 percent on Friday, with resource shares climbing on strong earnings from the energy and materials sectors, but the index still recorded its seventh weekly decline in a row.

Among the leaders in the oil patch, Suncor Energy (SU.TO: Quote, Profile, Research, Stock Buzz) gained 4 percent, and Petro-Canada (PCA.TO: Quote, Profile, Research, Stock Buzz) rose 2.6 percent, after both companies reported a jump in profit on Thursday.

The sector held up in the face of a $2.23 drop that took crude to $123.26 a barrel on Friday, racking up a decline of more than $23 in two weeks on concerns over faltering demand.

The materials sector, home to resource shares, also saw gains after this week's quarterly results from Potash Corp of Saskatchewan (POT.TO: Quote, Profile, Research, Stock Buzz), which rose 4.6 percent, and Fording Canadian Coal Trust (FDG_u.TO: Quote, Profile, Research, Stock Buzz), which gained 5.8 percent.
