Factor analysis has been carried out in the case of growth, yield and quality characters of small cardamom presently based on a study of eleven genotypes grown under typical humid tropical climate in the cardamom hill reserve area of Kerala State of India to analyze the association between them. The seven growth characters studied could be grouped in to two based on factor loading with number of bearing tillers showing maximum factor loading in the first group and leaves per tiller showing maximum factor loading in the second group. Out of the two factors identified among the growth characters the first factor with four characters contributed 33.79% of variance exhibited by the growth characters studied and the second factor with three characters contributed 31.08% of variance. Characters with the highest factor loadings can be considered as lead characters and the present analysis showed that number of bearing tillers and leaves per tiller are the most important characters of cardamom based on which selection could be carried out. The yield characters also could be grouped into two factors and the two factors together contributed 58.57% of cumulative variance contributed by the yield characters. Yield per plant and inter nodal length of panicles were found to be the lead characters among them. In the case of quality characters nine out of eleven characters studied could be grouped into three factor groups with moisture content, volatile oil and 100 capsule weight- dry as the lead characters.
