Pinus tecunumanii crosses easily with P. caribaea, P. oocarpa and P. patula. Successful crosses have also been made between P. tecunumanii and P. taeda, P. elliottii, P. greggii, and P. radiata by CAMCORE members but seed set has been low or highly variable. Pinus tecunumanii vegetatively propagates easily and hopefully low seed yields can be offset by family multiplication of most hybrid progeny. Pinus tecunumanii offers to breeders a number of traits that may be valuable in hybrid combinations such as fast growth, suitable wood quality, and in some instances superior drought tolerance (LE trees) and disease resistance. For example, LE sources of P. tecunumanii appear to be very resistant to Pitch Canker (Fusarium circinatum; syn. F. subglutinans f. sp. pini) in the seedling stage, a serious problem for both P. radiata and P. patula (in the seedling stage).
