“MVP” stands for Most Valued Producer. It is a strain that comes from the cross of “OG TAT” and Melmac (this genetic line is also referred to as the True Albino Melmac, or TAM project). Despite it being a part of the TAT genetic line, MVP mushroom genetics are NOT true albino. Even though it is not an albino, it’s still interesting to study because it’s distinct from the 2 varieties that created it. However, later down the line it gave way to an albino mutation known as Albino MVP (AMVP).
