I don't know for FETs, but on normal Japanese transistors it signifies the
hFe group (amplification factor).

Are you talking about the dual-gate MOSFET used in some Yaesu
equipment?

I think the GR suffix in that case has to do with selection for low
noise and low intermod.

For FETs it means the Idss value,
Y (yellow) = 3-7mA,
GR (green) = 6-14mA

To be more exact, for the 2SK73 the Idss values are these given
