Study on RAPD Marker Linked to Sex in Siraitia grosvenorii
RAPD (Random Amolified Polymorphism DNA) was employed to detect molecular markers linked to sex in S. grosve-norii by BSA (Bulked Segregant Analysis). 18 RAPD markers linked to sex were selected in BSA by screening 90 primers. Only the marker amplified by S1431 was present in all 8 male individuals tested while absent from all 8 female individuals tested. It showed that S1431 was a male RAPD marker linked to sex.
