Black pepper is cultivated in Andaman and Nicobar Islands, India as a spice crop. During a survey performed in June of 2007 in South Andaman, two kinds of leaf anthracnose symptoms were observed. The classic symptom, angular to irregular or circular brownish lesions with a chlorotic halo and pinhead

BACKGROUND
Data analysis of omics data should be performed by multivariate analysis such as principal component analysis (PCA). The way data are clustered in PCA is of major importance to develop some classification systems based on multivariate analysis, such as soft independent modeling of class
