Abstract :

 Gladiolus (Gladiolus x hyidus Hort.), the queen of the bulbous ornamentals, is the leading geophyte 

grown worldwide for cut flower trade and garden displays. Molecular characterization of plants relies on 
high yields of pure DNA samples and optimized PCR protocol. In the present study, optimization of PCR conditions for 
ISSR analysis of Gladiolus genotypes was done at Indian Institute of Horticultural Research, Bengaluru during 2011 – 
2012. ISSR protocol was optimized for template DNA, dNTP, primer, and Taq polymerase concentration and annealing 
temperature. Template DNA of 80 ng, 1mM of dNTP, 0.33 U of Taq DNA polymerase, 1 μM primer gave highly reproducible PCR products. Reproducible amplifiable products were observed in all PCR reactions. The present optimized 
protocol for ISSR–PCR is suitable for molecular diversity analysis of Gladiolus genotypes.
