His leap eclipsed by one centimetre the previous mark set by Randy Williams of the U.S. in the qualifying round of the 1972 Summer Olympic Games in Munich nearly 40 years ago.
Morgunov, who turned 19 on 9 February, set his previous best of 8.10m in a spirited battle last July at the European Junior Championships. Morgunov went on to claim that title with a wind-assisted 8.18m (+3.6) jump.
The leap in Cheboksary also sent Morgunov to the top of the world lists, equalling Briton Greg Rutherford's mark from early May as the farthest in the world this year.
Coming in what appears to be Morgunov's 2012 outdoor debut, the teenager will certainly command the spotlight at the upcoming IAAF World Junior Championships, Barcelona, 10-15 July.
