SOMACLONAL VARIATION IN PROTOPLAST-DERIVED STRAWBERRY PLANTS
Chromosome doubled plants were clearly discernible from the normal, octoploid plants in that they has thicker and less numerous leaves, shorter and thicker petioles and larger flowers. Most of the mixaploid plants were stunted and had wrinkled leaves and some of them did not survive in the field. Variation was also found among the octoploid plants in characteristics such as date of flowering, runner production and length of the petioles. Interestingly there was also a large variation in size, colour and shape among berries from different protoclones. Preliminary experiments indicate that these variations cannot be detected on DNA level using DNA-fingerprinting.
