Abstract: The Present investigation were conducted during 2010- 2011 at the Research Farm of Janta Vedic College, Baraut, Baghpat (U.P.). The thirty nine genotypes of Indian mustard (Brassica juncea L. Czern and Coss) were shown in a Randomized block Design (RBD) with three replication at the Research Farm. Five Competitive plants from each plot were randomly selected from all three rows for recording data. Observations of all the characters were recorded on single plant basis except for days to flowering and days to maturity. Average of these selected five plants in respect of different plant characters were used for statistical analysis. The data were recorded for the following characters namely, Days to 50% flowering, Days to 80% maturity, Plant height (cm), Number of primary branches per plant, Number of secondary branches per plant, Length of siliqua (cm), Number of seeds per siliqua, 1000-seeds weight (gm), Biological yield per plant(gm), Harvest index (%), Oil content and Seed yield per plant (gm). All the 39 genotypes were classified in to five clusters. Clusters II had maximum number of genotypes (14) and second larger group of genotypes was in cluster III and V with (9) genotypes each. The cluster I had genotype (6) and minimum genotypes (1) in cluster IV.
