Abstract

  1. 1.

    Identification of nearly 150 lettuce varieties as seedlings in the three-leaves stage was found possible.

  2. 2.

    As in practice a limited number of varieties is used, different identification keys for restricted groups seem more useful than one key for all 150 varieties, which would be needlessly complicated.

  3. 3.

    As an example, an illustrated identification key is given for the ten varieties which are grown in the Netherlands.

Samenvatting

  1. 1.

    Het is mogelijk gebleken bijna alle 150 rassen van een verzameling slarassen te determineren aan de jonge plant.

  2. 2.

    Daar men in de praktijk steeds met kleinere groepen van rassen werkt, schijnen verschillende identificatie schema's voor beperkte groepen nuttiger dan een schema voor alle 150 rassen. Dit laatste zou nodeloos ingewikkeld zijn.

  3. 3.

    Als voorbeeld wordt een geïllustreerd determinatie-schema gegeven voor de tien rassen welke in Nederland worden geteeld.
