Plant breeders may use one of three basic strategies to simultaneously select multiple traits: tandem selection, independent curling, and selection index. Plant breeders often handle very large numbers of plants in a segregating population using limited resources (time, space, labor, money, etc.). Along with the large number of individuals are the many breeding characters often considered in a breeding program. The sooner they can reduce the numbers of plants to the barest minimum, but more importantly, to the most desirable and promising individuals, the better. Highly heritable and readily scorable traits are easier to select for in the initial stages of a breeding program.
