You can see the library agricolae for the functions LSD.test, HSD.test, and Waller.test for Waller-Duncan. The criterion is that LSD is more used for few treatments and HSD for many treatments (more than 5) the test of Waller is Bayes and minimizes the two types of error (I or II). In experiment with clones, we prefer Waller-Duncan.

I'm designing a experiment in order to compare the growing of
several clones of a tree specie. It will be a complete randomized block
design. How can I decide what model of mean comparision to choose? LSD,
HSD,TukeyHSD, Duncan,...? Thanks in advance
