Dilip,
As you're creating new ROIs, add them to the ROI Manager.
At the end of the loop, use the Combine command. Also check the other
roiManager() functions at:

jerome

This example creates 2 ROIs and combines them.

run("Blobs (25K)");
makeRectangle(7, 21, 56, 49);
roiManager("Add");
makeRectangle(113, 47, 56, 49);
roiManager("Add");
roiManager("Combine");
