The WRU made the announcement on Tuesday, after WRU Chief Executive Steve Lewis had put the fiishing touches to what has been a long period of negotiation with all parties.
"The players were all very comfortable with the three of them during the tour to Argentina and they have all made excellent contributions to squad sessions since we returned.
"It is great that we now have an all-Welsh coaching team, although that was never a pre-requisite in my mind - we have selected the best people possible to prepare the Welsh team for the 2007 Rugby World Cup."
Wales face Australia, the Pacific Islands, Canada and New Zealand in next month's Invesco Perpetual Series at the Millennium Stadium and will play two games at home, against England and Ireland, in the 2007Six Nations Championship.
After that there are two Tests scheduled for the summer tour to Australia and three Rugby World Cup warm-up matches against England (away), Argentina and France (both home) next August.
At the 2007 Rugby World Cup Jenkins' men will face Australia, Fiji, Canada and the team that emerges on top from the final Asian qualifying tournament in Colombo at the end of next month, involving Japan, South Korea and Hong Kong, in their Pool. If they finish in the top two they will be guaranteed a quarter-final place.
All three members of Jenkins' techincal team are ex-internationals and their appointments takes to nine the number of the national management team who have represented Wales.
Jenkins himself played for Wales against Japan in an uncapped match in Tokyo in 1975, while his attack coach Nigel Davies won 29 caps, and team manager Alan Phillips 18 caps and one Lions tour.
The technical team consists of McBryde, with 37 caps and one Lions tour, Phillips with 10 caps, and Neil Jenkins with 87 caps and two Lions tours.
Finally, fitness coach Mark Bennett won 3 caps, physiotherapist Mark Davies also won 3 caps and analyst Alun Carter won 2 caps.
"I am delighted Gareth has opted for a home grown group to take Wales into next year's Rugby World Cup," said WRU chief executive Steve Lewis.
"One reason for the formal announcement has come later than hoped is because we wanted to sort out exactly how we split the time and energies of the three technical coaches.
"Neil and Robin will carry on working within the wider High Performance Unit as national skills coaches to our academy players while Rowland is head coach at Neath.
"All three coaches will continue to have a coaching role within the international age grade structure, and this indicates just how close the relationship now is between the national squad and the rest of our High Performance group.
"All three coaches have continued to work with Gareth and the players since the summer tour and will be fully committed to their national roles. We feel we have found the right balance in our working structure for this important year and beyond."
Another change behind the scenes will see Alun Carter's technical analysis team become full-time members of the WRU staff. This means their work will broaden out from the national squad to working with all age grade teams and academies.
Smart move!
