Reciprocal Full‐Sib Selection¹

Abstract

Reciprocal full‐sib selection is a breeding procedure for concurrent population improvement and hybrid development. Reciprocal full‐sib selection should be an efficient procedure for crop species in which non‐additive genetic effects, as well as additive, are important in the expression of hybrid superiority. Full‐sib progenies are yieldtested, and selections are made for improvement of the two parental populations. These same yield trials also are the first season of the evaluation and development of single crosses for each cycle of selection. The use of reciprocal full‐sib selection in a comprehensive breeding program provides a flexible plant‐breeding procedure
