Ylocter’s Waelecho;, Program 
Yoder Bros. Inc., started a re-selection program in the early summer of 1947. During June and 
July only the most vigorous plants were selected and the cuttings were removed by holding the 
cutting with sterile tissue and snapping the tip off without the use of a knife. Each cutting was so 
handled and then placed in an isolated propagation bench spaced 5 inches by 5 inches. After root- 
ing, these selected cuttings were planted one to a 7 inch pot and each labeled and numbered. As 
this was done with each variety listed one can readily figure out the amount of equipment and 
space this program consumed. All containers and growing media were steam sterilized. These plants 
were grown under conditions where insects were constantly under control. Careful handling of plants 
so as not to injure the cells was constantly in vogue. 
From time to time a trained worker checked each plant and if any abnormal growth was noted 
the plant was removed from the isolation house and destroyed. 
FLOWERING THE RE-SELECTED STOCK 
In the spring of 1948 a uniform number of cuttings was taken from each pot and planted in a block 
and allowed to flower. Each lot was labeled to correspond with the number of the mother stock 
plant. 
During the growing season of 1948 these re-selected flowering trials were checked weekly and 
volumes of data were collected. The flowering trials were grown under standard growing practices. 
As fast as any evidence of stunt showed up on these nuclear flowering trials the mother stock plant 
was destroyed and if any other cuttings were propagated from that plant they too were destroyed. 
It is remarkable to notice that varieties such as Blazing Gold, Betsy Ross, Good News, Friendly 
Rival and others that were badly stunted in 1947 season were practically free from stunt in the 1948 
re-selected flowering trials. 
1949 COMMERCIAL CUTTINGS 
The stock plants that are to be used for 1949 cuttings will come from single plant selections 
that showed no stunt in the flowering trials of 1948. In other words the cuttings will come from selected 
re-selected stock. The same safeguards that were used in growing the re-selected stock plants in 1948 
will be followed with this crop of selected re-selected plants.
