Available : Md Retrieved : 27 A field experiment was conducted with 25 mustard (Brassica spp . L) genotypes on the farm of Hajee Mohammad Danesh Science and Technology University , Dinajpur , Bangladesh from November 2009 to February 2010 , to study the genetic diversity present among the genotypes . Eleven quantitative characteristics , namely plant height , days to 50% flowering , days to maturity , number of primary branches per plant , number of secondary branches per plant , number of siliqua per plant , diameter of siliqua , length of siliqua , number of seed per siliqua , 100 seed weight and yield per plant were taken into consideration . The analysis of variance revealed a remarkable variability among the genotypes in terms of the specified characteristics . Cluster analysis was used for grouping the 25 mustards (Brassica sp . L) genotypes into six clusters . Cluster II had the maximum number (13) of genotypes , while Clusters IV , V , and VI had the minimum number (2) of genotypes . The highest inter - cluster distance was observed between Clusters I and IV , while the lowest inter - cluster distance was observed between Clusters V and VI . Cluster II (D = 4 . 91) had the highest intra - cluster distance , while Cluster II (5 . 607) had the lowest intra - cluster distance . The characteristics such as plant height , number of secondary branches per plant , and number of siliqua per plant contributed greatest towards the divergence in the mustard genotypes . Considering diversity analysis , the genotypes , BARI - 11 , BARI - 12 , and BARI - 9 from cluster III had the highest yield , early flowering , and fruit maturity ; the genotypes DAULAT and BARI - 14 from Cluster IV had the highest number of siliqua per plant , number of secondary branches per plant , and yield per plant and may be considered as the best parents for future hybridization program .
