Genetic Diversity and Relationships among Diploid and Tetraploid Cotton Using RAPD Markers

摘要

Gossypium species (+49) represent a vast resource of genetic diversity for improvement of cultivated cotton.To determine intra- and inter-specific genetic diversity and relationships,we employed 30 RAPD random detainer primers on twenty eight cotton accessions from 2 diploid cultivated species (G.arboreum,G.herbaceum) and 2 tetraploid cultivated species (G.hirsuturn,G.barbadense).
