This study was aimed to examine the genetic diversity and population
structure of Indian melon landraces with special reference to disease and
insect resistance loci. Thirty-six simple sequence repeat (SSR) markers
along with seven markers at disease and insect resistance loci were used
for this purpose on a panel of 91 accessions available at Indian Institute
of Horticultural Research, Bengaluru, India. Model-based structure analysis
revealed the presence of four groups that were consistent with the
results of principal coordinate analysis (PCoA). The delineation of populations
was mostly based on geography with improved varieties as a separate
group. Ten accessions have been identified to possess beneficial
alleles at all the selected disease resistance loci and shall be useful for
incorporating multiple disease resistance after phenotypic validation. The
results obtained in the current study demonstrate the importance of the
Indian melon group as a valuable genetic reservoir and the need to plan
strategies for its conservation and utilization in breeding programmes.
