Abstract
Waxy corn hybrids classification by multivariate analysis
Variety group classification helps the farmer to choose a favorite variety and has benefits for plant breeder to plan and choose it as germplasm in breeding program. The objective of this experiment was to classify waxy corn hybrids by multivariate analysis. Nine hybrid varieties were tested in 4 environments with randomized complete block design. Seventeen trait means were analyzed by cluster analysis and principal component analysis to be variety group classification. Group classification by cluster analysis classified hybrids to be 3 clusters. KKU1116, KKU2901, PEK and GR484 were classified in the 1st cluster whereas KWSX91, TSW, NSW and BW were classified in 2nd cluster. The 3rd cluster has only one variety as WPP. For principal component analysis, traits were extracted to 4 principal components and classified hybrids by 3 dimension graph to be various patterns according to principal component axis relationship. Synchronized of variety groups classified by cluster analysis and principal component analysis depended on total variance extracted in principal component.
