tailieunhanh - Principal component analysis in genetic resources of Chinese millet (Setaria italica (L.) Beauv.)

Field experiment was conducted in 50 Chinese millet genetic resources to assess the genetic divergence for 12 metric traits through Principal Component Analysis. The ANOVA revealed existence of highly significant variation for all the traits examined. About per cent of total variation accrued through Principal component analysis exhibited four Principal components (, , and PC4- ) retained based on the Scree plot and threshold Eigen value greater than one (>1). The PC1 with prime economical traits viz., days to 50% flowering, days to maturity, culm branches, thousand grain weight, number of productive tillers / plant and flag leaf blade length accounted for maximum variance () connoting that these traits be given priority in future Chinese millet breeding programmes. | Principal component analysis in genetic resources of Chinese millet Setaria italica L.
