AUSTRALIA'S grains research body is operating without a board, after the Agriculture Minister failed to appoint one by the September 30 deadline.

Responding to questions from Shadow Parliamentary Secretary for Agriculture Richard Colbeck, Agriculture Minister Joe Ludwig said the matters were "being considered".

Senator Colbeck also accused Senator Ludwig of being a "city slicker Minister" who was "completely disconnected" from his portfolio.

"Given that those associated with GRDC say they are in the dark as to why there is no final appointment of the board, can the Minister explain how it's acceptable that one of the biggest rural development corporations, with an annual expenditure of $120 million, can be left without a board of directors because the Minister has not got around to signing off on the file?" Senator Colbeck asked.

Senator Ludwig said the grain industry was "important".

"It is a matter that is currently under consideration by government, we will advise in due course," Senator Ludwig said.

"They (the GRDC) will be advised shortly of the successful candidates ... it is important to ensure that they do have a proper representation within the board."
