Principle Component analysis
In present set of experiment, out of total 11 (PCs)
five principle component (PCS) were obtained
having >1 Eigen value. All these five PCs
contributed 65% in total variability amongst the
upland cotton genotypes which were assessed for
genetic diversity for fiber quality traits, earliness
and CLCuD (Table 3). The remaining 35% of the
total variability towards total variation was
contributed by other components.
