The resulting lines were taken through six rounds of selfing without any intentional selection (Figure 1).
Although used originally, likely as a means to enable the propagation of select phenotypes, grafting became a major intentional selection tool for soil and climate adaptation, disease resistance, improved productivity, and fruit quality.
It should be an intentional choice".
Was that an intentional choice?
Gerke said that was an intentional choice.
For each generation, the individuals were reared without intentional selection in a controlled environment to avoid environmental effects and biases in selecting the genitors for the next generation.
This process often includes an initial phase of unconscious selection by farmers for several thousand years, followed by a subsequent breeding phase of intentional selection of favorable traits by breeders1.
Artificial selection is the intentional selection of traits in a population of organisms.
A possible interpretation of this process as implying directional, and even intentional, selection, was at the same time downplayed in the published work through the importance given by Darwin to the role of "unconscious" selection, a concept not encountered in the Natural Selection manuscript.
We had a wide range of exposures available to study that resulted from the intentional selection of geographic sites with varying water quality characteristics that produced different distributions of chlorinated and brominated DBP species.
For obvious reasons, the form of artificial selection that Darwin dubbed methodical selection has also been called "deliberate" or "conscious" or "intentional" selection (e.g., Harlan et al 1973; Heiser 1988; Zohary 2004; Emshwiller 2006).
