A Strategy for Finding the Optimal Scale of Plant Core Collection Based on Monte Carlo Simulation
Figure 4
Principal component plots of core accessions and reserve accessions in the sampling percentages of 6.07%, 10%, and 15%. The axes represented the first two principal components. The upward pointing triangles represented the core accessions; the crosses represented the reserved accessions. The left column showed plots for subcore collection constructed by LDSS method based on Seuclid distance combining UPGMA cluster method (treat); the right column showed plots for subcore collection constructed by complete random selection (CK).
