Tohoku Univ. Technology : A New codominant CAPS marker for sex genotype identification in asparagus : T20-754
DNA marker to reduce the time required for asparagus breeding
Garden asparagus is a dioecious species, with male [XY] and female [XX] individuals. Since male individuals are preferred over females for agricultural production, all-male cultivars have agronomic advantages over mixed-sex cultivars. To produce an all-male cultivar, it is important to obtain a supermale [YY]. Given their morphological similarities, males and supermales are usually distinguished by genetic analysis. Although two sex-linked codominant markers (Asp2-SP6 and RM17) have been reported previously, their ability to distinguish the sex in A. officinalis and other dioecious Asparagus species was limited. We developed a new CAPS marker (SSM01). SSM01 is applicable for discrimination between X- and Y-specific sequences in various A. officinalis and purple asparagus cultivars, also in three dioecious Asparagus species.
