Quantitative DNA analysis of CMS

CMS plants (Cytoplasmic Male Sterility) have lost their capability to produce fertile pollen. This male sterility is based on a change in mitochondrial DNA sequence.

CMS is a natural process observed in onion, sunflower, carrot, Japanese radish and many others.
In hybrid breeding CMS plants are commonly used for seed production. Unwanted self-pollination can be prevented, i.e. a controlled pollination is possible.

This technology finds its application especially with cabbage varieties like broccoli, cauliflower, kohlrabi, white cabbage or chicory.
According to regulation „2001/18/EG“ CMS hybrids are not considered genetically modified plants if both parent plants can be crossed in a natural way.

Many organic farming associations refuse the application of CMS technology because it could go beyond natural species boundaries.
Impetus Bioscience has developed several methods for the specific detection of CMS. We have the knowledge and the state-of-the-art technology even to give precise quantitative information.
