Key words: Musa textilis L. Nee, principal component analysis, GxE interaction, Pearson’s correlation, cluster Analysis.

Abstract

Taximetric statistical methods were carried out on morpho-agronomic traits from three Manila hemp (Philippine abaca) varieties planted in three locations in Southern Mindanao, Philippines. Principal Component analysis (PCA) resulted in the extraction of five principal components which collectively accounted for 99.85% of total variance. Continue reading
