Diversification of quantitative morphological traits in wheat.

ABSTRACT:

Background and aims

The development and morphology of crop plants have been profoundly altered by evolution under cultivation, initially through unconscious selection, without deliberate foresight, and later by directed breeding. Wild wheats remain an important potential source of variation for modern breeders; however, the sequence and timing of morphological changes during domestication are not fully resolved.

Methods

We grew and measured 142 wheat accessions representing different stages in wheat evolution, including three independent domestication events, and compared their morphological traits to define the morphospace of each group.

Key results

The results show that wild and domesticated wheats have overlapping morphospaces, but each also occupies a distinct are
