Does IP Location of backlinks effect Results?

I am suprised to discover that I have a lot of first page results in http://www.google.co.in (useless to me) and I can't be found as easily on Google.com for competitive keywords.

I have a good number of backlinks from Indian sites and this leads me to ask the question: "Does the IP location of backlinks effect the search results?"

I would welcome any thoughts, or comments. If you don't agree, feel free to monkey slap me.
