Ankit, representing LIC, leapt to 7.87m in his penultimate jump to equal the 16-year-old meet record set by Sanjay Kumar Rai of Railways.
National record holder Kumaravel Prem Kumar's miserable season continued as he was pushed to third place with a best effort of 7.53m. Railwayman Prem Kumar's national record stands at 8.09m.
M Arshad of Services took the silver with a jump of 7.58m.
22-year-old Ankit had finished fifth in the IAAF World Youth Championships in 2009 and won a bronze medal at the Asian Junior Championships in 2010. He has not won a medal at a senior international event.

Luka, representing Railways, ran 2:03.88 to win gold in women's 800m race while Poovamma, turning up for ONGC, came first in 400m in 53.59 seconds. Luka had won a silver and Poovamma a bronze in their respective individual events in Incheon Asian Games while both of them were members of the gold-winning 4x400m relay quartet.
Both the athletes ran well below their personal best but that was expected as the National Open was the last event of the year after a gruelling season which had two major international events in Commonwealth and Asian Games.
"I wanted to win a gold for my department (ONGC) and I am happy to have done that. The (below-par) timing was expected after a long and gruelling season. I have not thought of the timing and this (timing) has no significance," Povamma said after her race.
