Guava (Psidium guajava L.) is one of the important tropical fruit crops of India. Detailed horticultural and systematic study of the species and cultivars is lacking. Molecular markers can complement morphological characterization of cultivars in identification and diversity analysis. RAPD analysis of some guava cultivars of North 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.
