COMBINED SELECTION IN EARLY GENERATION TESTING OF SELF-POLLINATED PLANTS

Seven selection indexes based on the phenotypic value of the individua l and the mean performance of its family were assessed for their appli cation in breeding of self-pollinated plants. There is no clear superi ority from one index to another although some show one or more negativ e aspects, such as favoring the selection of a top performing plant fr om an inferior family in detriment of an excellent plant from a superi or family.
