 ABSTRACT

An experiment was carried out using forty five accessions of soybean laid in a randomized block design with three replications at the research farm of CCSHAU, Hisar in 2014 to determine the contribution of nine morphological traits to the total variability in soybean using Principal component analysis. Results revealed that the first 3 principal components accounted for 79.37% of the total variation. PC1 contributed 52.85% of the total variation and dominated by 100-seed weight, number of days to maturity, number of branches per plant, pods per plant, seed yield per plant and plant height. The second principal component explained an additional 14.94% of the total variation dominated by highly positive pod length and number of seeds per pod while the PC3 explained an additional 11.58% of the total variation and only number of days to 50% flowering showed positive relation with the third component (PC3) signifying its importance in divergence.

Key words: Principal Component Analysis, Soybean.
