What is it about?
Knowledge on performance of genotypes and interrelationships among traits is very important for sugarcane breeding program. Therefore, many characters are evaluated simultaneously in the sugarcane phenotypic evaluation process. In this study, we used the Principal Component Analysis (PCA) to identify representative traits for phenotypic characterization of sugarcane, and thereby to select superior clones in the breeding process. Five quantitative and two qualitative traits of sugarcane were studied from the PCA. These major components represented for 58.13% of the variance. Cluster analysis has allowed us to divide the 148 clones of sugarcane into 5 groups. The high genotypes diversity of selected sugarcane is reflected by the genetic diversity revealed within the population.

Why is it important?
The selected genotypes were thought to have great promise to be good commercial varieties in future and were advanced for further testing and progression.
Perspectives
Morphological diversity among the sugarcane clone germplasm was well defined by both principal component and clustering analyses. Considering the different morpho-bio-agronomic descriptors, it has been possible to observe a noteworthy inter and intra-group diversity. This recommends the likelihood of attaining, through selection, suitable genotypes combining the high yield with desirable traits. The selected genotypes were thought to have great promise to be good commercial varieties in future and were advanced for further testing and progression.
