The inaugural Guinness Pro14 Rainbow Cup will kick off with three rounds of inter-provincial derbies. 

This season's Guinness Pro14 wraps up tomorrow when Munster take on Leinster in the final. The new Rainbow Cup tournament, involving 16 teams - four of which will be from South Africa - then runs from 24 April until 19 June.

The Vodacom Bulls, Emirates Lions; Cell C Sharks and DHL Stormers are the non-European teams taking part.

Changes to scheduling and format of the competition have been made to limit travel where possible meaning the opening three rounds will see derby fixtures across Ireland, Italy, Scotland, South Africa and Wales.

In Round 1, Ulster host Connacht and Leinster and Munster square up again at the RDS. Two weeks later Leinster head to Connacht with Ulster travelling to Munster, and seven days after that Munster host the Westerners while Leinster welcome Ulster.

Rounds 4 to 6 will see the four South African 'Super' franchises play their away games in Europe. Those fixtures will be confirmed once all appropriate travel approvals have been sanctioned by the relevant authorities and governments. No teams from Europe will travel to South Africa.

A total of six rounds will take place with all teams ranked in a single league table. The top two teams will then play each other in the Guinness Pro14 Rainbow Cup final on 19 June.
