marker trait

mark·er trait

a trait that may be of little importance in itself but which by association, linkage, or other means facilitates the detection, anticipation, or understanding of a disease or (for genetic diseases) the localization of the causative gene on the karyotype.

1922; Zeven and Schachl, 1989), whereas few easy to score morphological marker traits are available, (iii) statistical procedures for processing quantitative trait information are readily available, (iv) quantitative trait information adds to an understanding of ideotype-performance relations, and (v) heterosis may show closer association with distance measures based on such traits or explanation of heterosis may be enhanced by adding morphological measures of distance as another independent variable (Cox and Murphy, 1990).
A major advantage of distance measures based on marker traits is that a germplasm collection can be open-ended and flexible.
