The genetic divergence among 12 genotypes was estimated using D2 analysis by Tocher's method. Altogether, four clusters were formed. The genotype Solanum indicum appearing in cluster III was highly resistant; the genotypes Solanum gilo, Solanum incanum and Solanum anomalum in cluster 1 were resistant; Pusa Purple Cluster, Bhagyamathi, Annamalai, APAU-4, Nurki and Singhnath forming cluster IV were moderately resistant; and (Pusa Kranti and Aushey) cluster II was susceptible to Leucinodes orbonalis.
