MLN Scoring

A standardized 1-9 MLN scoring scale has been developed by CIMMYT for assessing hybrids and breeding lines. Visible differences occur depending on whether hybrids or breeding lines are being scored.

The 1-9 scoring scales used are as follows:

  1. Hybrid Scale
  2. Breeding Line Scale
