4. Seedling classification for red or green base. Seedlings germinated by the above method can be classified accurately for the green base (rg or Rg), or red base (rr or Rr). The tip of the first true leaf has been found the most reliable place for classification. If any antho-cyanin color is present it will appear at the tips of the leaves. Seedlings so germinated and classified can still be planted without injury or setback. (This method of classification is not new. It is used by Dr. Stadler and his students at the University of Missouri. It is cited here as it may be helpful to some unfamiliar with it).
