Sex identification in canarium odontophyllum miq. (Dabai) using random amplified polymorphic DNA (RAPD) marker
Canarium odontophyllum Miq. is a perennial plant native to Malaysia, Indonesia and Philippines. The pistillate plants bear fruits twice a year and are more preferable than staminate plants. Thus, sex determination in Canarium odontophyllum at seedling stage is very important for crop improvement pro...
