What is the optimal selection intensity of seedlings (stage 1) in sugarcane breeding programs?* [Full subscriber]

Abstract      Selection of seedlings in sugarcane breeding programs is a major task usually undertaken annually. Sugarcane breeding programs worldwide differ in how this is done, particularly in relation to intensity of selection (i.e. the proportion of seedlings selected to be advanced to the second stage of selection), with some programs selecting very intensively (e.g. 1% of seedlings taken to stage 2) while others select more liberally (e.g. >15% taken to stage 2). These differences partly reflect views on effectiveness of seedling selection: in theory high selection effectiveness should favour more intensive selection options than if selection is ineffective.
