The breeder could use the need for cold as a criterion in selection for earliness and to improve the uniformity of his varieties. The length of the core was negatively correlated with the need for cold. This character was also of use in testing of varieties. The result of early forcing could be improved by previously cooling the roots.
Practical trials on forcing without covering soil and selection for core length confirmed the results of the research.
