Genetic diversity in eggplant for resistance to shoot and fruit borer.
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. Solanum gilo, Solanum incanum and Solanum anomalum in cluster I were resistant. Pusa Purple Cluster, Bhagyamathi, Annamalai, APAU-4, Nurki and Singhnath, forming cluster IV, were moderately resistant. Pusa Kranti and Aushey (cluster II) was susceptible to Leucinodes orbonalis.
