No genetist or scientific breeder will deny this. It is simply the question of the interpretation of how the results were obtained that is in doubt and whether these results can be considered as permanent, new unit characters. Before we can thoroughly understand this subject it is probable that each individual case will require to be carefully analyzed, to deter- mine the nature of the advance made and the interpretation of the process or proc- esses concerned. At present we can only partially ...understand the phenomena pre- sented. It appears to me that we are dealing in breeding with two markedly distinct types of selection, based on different prin- ciples and arriving at different results, both right in principle and productive of equally valuable practical results, but of very different value, when considered from a strictly evolutionary standpoint. It would seem that such cases of im- provement as are illustrated by the sugar beet indicate that the continuous selection, generation after generation, of maximum fluctuations shown by a character, will re- sult in maintaining a strain at nearly the maximum of efficiency; and that within a pure race the progeny of a maximum variate which would probably be classed as a fluctuation, does not regress entirely to the mean of the race in the first genera- tion succeeding the selection, but that we only have a certain percentage of regres- sion similar to the regression determined by Galton.
