A Study Of Hybrids Between Sugar Beets And Mangel Wurzels With Reference To Color Factors And Sugar Content, Boyd Berrey
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Preliminary unpublished work at the Salt Lake City Laboratory of the Division of Sugar Plant Investigations, Bureau of Plant Industry, United States Department of Agriculture, indicates that beets showing the Y color factor (9) were larger than sugar-beet types recessive for this color factor (y y).

Linkages between the R and Y color factors have been reported by Keller (9), and the results indicate a close linkage between color factors R …

It is of prime importance to be able to establish a date in the spring when the range has produced sufficient feed to keep livestock in thrifty condition, when it is reasonably safe from excessive trampling and packing of the soil, and when the more important key forage plants have attained sufficient development to withstand grazing use. Such opening dates, as well as the time to defer and rotate grazing and to remove livestock from the range, are dependent in part on the prevailing weather conditions and on …
