The large number of measurements required for most of the evaluated characters make their use in their totality impractical in breeding programs of the treated species, reason why it is suggested to use the number of palm heart per plant (NP) character in indirect selection for the production of total, base and first-rate palm heart, due to high genotypic correlations with these characters.
Morphological traits positively affecting the live body weight could be considered as indirect selection criteria for producing heavier lambs.
However, genetic gain by indirect selection may make it sufficient to measure only diameter at breast height (DBH) for improving this species.
The trait agronomic value can be used in the process for indirect selection since it presented a high correlation in the phenotypic and genotypic coefficient with grain yield.
Linear relations researches among traits of forage turnip (Raphanus sativus L.) and white lupine (Lupinus albus L.) indicated that the stem diameter and the number of pods per plant, respectively, have a positive linear relation with fresh and dry matter and it can be used for indirect selection of plants (Cargnelutti Filho et al., 2014).
For inter-and subtidal environments, the results for indirect selection were higher than for coastal and PS sites, but similar predicted genetic gains for direct versus indirect selection were only evident for survival.
The selection gains were estimated among families based on three selection criteria: direct selection, indirect selection, and selection-based index considering the selection intensity of 5% of top families.
As shown by Glazer and McGuire (2000), the different risk types have different preference structures, a fact that can be used for indirect selection. The returns to indirect selection through the benefit structure depend on factors that are not observable by the regulator.
Results of the biplot analysis indicated that drought tolerance in tomato does not necessarily have to be associated with robust root system and therefore the indirect selection strategy may rely on shoot traits.
Use of molecular markers would allow indirect selection for rust resistance independent of environmental effects (12).
