Bulletin of the of Agriculture . espread distribution inyoung orchards. Under normal conditions a twig originating as abud variation and bearing only a single variable fruit will in a fewyears develop into a large branch bearing the same character of securing bud wood for propagation according to the methods whichhave prevailed in the past, no thought has been given to the possibleoccurrence in the trees of branches bearing fruits of variable strains,and as a result among trees so propagated there is usually found aconsiderable proportion of variable ones. On account of this previouslack of knowledge of the existence of variable strains, the percentageof such yariable-strain trees in the population of any locality has beengreatly increased with each bud generation. This fact is one of themost important reasons for securing individual-tree performance rec-ords and using such records as guides in the selection of trees fromwhich to obtain bud wood for propagation.
