摘要：
The author considers from the statistician''s point of view the problem of breeding new vars. of sugar beet. The breeder, with the purpose of increasing the sugar content, has to make a selection of vars. from a larger supply, multiply the seeds of those selected and compare them in field trials with some established standard. For economic reasons the breeder must ask: (1) whether he should select more vars. and, consequently, test them with fewer replications, or vice versa; and (2) what is the minimum number of replications necessary in field trials if he desires to have a fairly good chance of discovering a new variety which is actually better than the standard? To answer these questions is the main purpose of this paper.
