Hii Janak..

Their is no IIT which accepts Jee Mains score. If you want admissions in IITs then, first of all you should qualify Jee Mains exam and then qualify Jee Advance. Their are total 23 IITs in India and each of them accepts Jee Advance score for admission. 

Although the NITs and GFTIs accepts Jee mains score. You can get admission in these NITs and GFTIs if you have rank accordingly. Even Josaa is soon going to begin counselling process college allocation. If you want to know list of best colleges in India which take admission through Jee mains then I am providing you the following link-

HI there,
Hope you are doing well.
I am sorry to say but the admission in all IITs are conducted solely on the basis of JEE Advanced score.
With JEE Mains score, you can get admission in only NITs, IIITs or GFTIs and some regional colleges.
Hope it would help.
Thank You

No Janak, none of the IIT's accept JEE Mains score. You have to clear your JEE Mains cutoff and qualify for JEE Advanced which is approximately 45 days after the results of JEE mains. If you get a decent score in advanced, then you have a chance of getting into an IIT. 

But ther are several other colleges, rather nice ones like nit and iiit, which take admission through jee mains. So check which college you can get into:
