NEW YORK, Oct 11 (Reuters) - Kraft Foods Group Incplans to sell Maxwell House and Gevalia K-cup single-servecoffee pods compatible with Keurig brewing systems, a spokesmansaid on Thursday, in another blow to Keurig parent GreenMountain Coffee Roasters Inc .

The pods are not licensed by Keurig or affiliated in anyway, Kraft spokesman Basil Maglaris told Reuters. That meansthat Green Mountain will not receive any royalties from theirsale.

The move by Kraft, which also owns the rival Tassimo one-cupbrewer, represents the first time a big-name coffee brand skirtsGreen Mountain in making cups for its market-leading system.

Following news of similar launches by private label brandsincluding Kroger Co , Safeway Inc and SupervaluInc , the move by Kraft adds more weight to the argumentput forth last year by Greenlight Capital's David Einhorn, whoquestioned the sustainability of Green Mountain's dominance.

Starbucks Corp and Dunkin Brands Group Inc's

Dunkin Donuts also sell cups for Keurig, but they arelicensed.

Maglaris said he expects the cups to be on U.S. retailshelves sometime in the next several months.

Green Mountain was not immediately available to comment.

Kraft also manufactures the Tassimo single-serve coffeesystem. Maglaris could not say whether the Keurig cups wouldcannibalize sales of Tassimo cups.

Green Mountain shares initially fell as much as 3.4 percenton the news on Thursday, but by midday were up 0.2 percent at$22.12. Kraft shares were down 1.1 percent at $45.81.
