Excerpt from Bulletins From the Ontario Agricultural College and Horticultural Experimental Station: Nos. 319 to 332; July, 1926 to December, 1927
In the summer of 1925 practically all the salable stock of fruit trees grown in Ontario, totalling was inspected by the writer. The mixtures amounted to about trees or one and one-half per cent. Of the total. Considering the opportunities for error in the various nursery operations, this is a remarkably good record. Based on total salable stock the lowest per centage of mixtures in any nursery was three-tenths of one per cent. And the highest, thirteen per cent. All trees untrue to name were eliminated in the nursery either by breaking down, or, where possible, labelling with the correct name. In 1925 nursery firms were issued certificates stating that certain kinds and varieties of fruits were true to name as they stood in the nursery rows. Further mixture, through carelessness, may occur during and after digging operations. Experience indicates, however, that most mixtures occur previous to digging time, mainly as a result of the use of incorrectly named budwood, etc. A mixture, once established, is likely to be perpetuated by the taking of bud wood, year after year, from the nursery stock itself. It may be mentioned, also, that some of the worst mixtures resulted from securing bud wood from trees in growers' orchards thought to be true to name, but which subsequently were shown to be incorrectly named.
