centgener

“If this determination of the "centgener power," as Hays calls it, should prove to be the true principle of selection, then indeed the analogy between natural and artificial selection would lose a large part of its importance.”

Species and Varieties, Their Origin by Mutation

“Only the parents with the largest power in the centgener of offspring are chosen, while all others are wholly discarded.”

Species and Varieties, Their Origin by Mutation

“This centgener power, or breeding ability, is tested and compared for the various parent plants as to yield, grade, and percentage of nitrogenous content in the grain, and as to the ability of the plant to stand erect, resist rust, and other important qualities.”

“Hereditary percentage and centgener power as marks by which intraspecific selection may be guided.”

Species and Varieties, Their Origin by Mutation

“Once attained, progress however, will be dependent on the selection principle, and the hereditary percentage, or centgener power or breeding ability, must be determined in each generation anew.”

“In some measure the members of the best centgener will manifestly be at an advantage, because they contain more fit specimens than the other groups.”
