The study on diversity of acid lime was undertaken using one hundred genotypes collected from twelve districts of West Bengal in the duration of 2015-17. Genotypes were selected for studies on the basis of in situ observation as well as information provided by the farmers. Based on consumer’s preference, six important quantitative fruit characters (fruit weight, rind thickness, juice percentage, number of seed, TSS: acid, ascorbic acid) were recorded. Descriptive analysis revealed a wide range of variation particularly in fruit weight, rind thickness, juice percentage and number of seed. The genotypes were grouped into eighteen clusters by Hierarchical cluster analysis. The major characters responsible for such grouping by canonical discriminant function were fruit weight, number of seed and ascorbic acid. PCA of six fruit characters of acid lime showed three components with cumulative variance of 67.6% According to biplot analysis, genotypes HRA 3, PMA 2, NAA 21 may be exploited for higher fruit weight; genotypes NAA 2, HGA 2, MUA 3, PMA 4 for higher juice content and genotypes NAA 24, PMA 6, NAA 5, NAA 1, BRA 5 for excellent biochemical quality.
