DNA Fingerprinting of Guava (Psidillm gllajava L.) Cultivars using RAPD Markers

Abstract

Guava (Psidium guajava L.) is one of the important tropical fruit crops ofIndia. Detailed horticultural and systematic
study of the species and cultivars is lacking. Molecular markers can complement morphological characterization
ofcultivars in identification and diversity analysis. RAPD analysis of some guava cultivars ofNorth India is presented.
Nine RAPD primers generated 133 amplicons discriminating all the 13 cultivars. Cultivar-specific bands were
identified for five cultivars. Statistical analysis revealed moderate genetic diversity among the cultivars investigated.
Present analysis demonstrates the feasibility of RAPD technique for DNA fingerprinting of guava cultivars.
