Fig. 1 in Bio-genetic analysis of resistance in tomato to early blight disease, Alternaria alternata

Fig. 1. Ward's clustering dendrogram of 35 tomato genotypes based on resistance to Alternaria alternata. Note: Cluster Ӏ consisted of moderately susceptible and moderately resistant genotypes, Cluster ӀӀ consisted of resistant genotypes and Cluster ӀӀӀ consisted of highly susceptible genotypes. Disease severity was assessed based on infection percent (0–100) against the scoring scales of: 0, 5, 10, 25, 50, 75, or 100%.
