Graft compatability excellent with peach, nectarine, apricot, plum and almond.

Anchorage is excellent with no suckering.  

Penta delays almond bloom by 5-6 days compared to GF677.  It reduces peach and nectarine vigour by 10-20%.

It has similar vigour to peach seedling (about 90%) and advances fruit maturity by several days with improved fruit colour.

Fruit size in apricot is improved over plum rootstock (Myro 29c).

Yield efficiency similar to peach seedling.

With apricot, vitour is reported to be just less than peach seedling.
