Forty ginger genotypes collected from different parts of the country including one recommended variety Himgiri as check were planted, at the Experimental Farm of the Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif season of 2011 and evaluated for different yield and yield contributing traits. The observations were recorded on emergence, number of tillers and leaves per plant, leaf length and breadth, plant girth and height, length, girth, core diameter and weight of mother, primary and secondary rhizomes, number of primary and secondary rhizomes per plant, yield per plant, per plot and per hectare, incidence of rhizome rot, dry matter and oleoresin content. In the present studies, on the basis of genetic divergence, forty diverse genotypes of ginger were grouped into four clusters. This makes the genotypes to be highly divergent and maximum number of genotypes were accommodated in cluster-I. The average intra cluster distance was maximum in cluster-III and minimum in cluster-IV, whereas, maximum inter cluster distance was recorded between cluster-II and III. Cluster-II performed better for majority of traits viz. leaf length, length, core diameter and weight of primary and secondary rhizomes, dry matter recovery and yield per plant with lesser incidence of rhizome rot. Thus, on the basis of cluster means of different characters, effective clonal selection can be made for obtaining superior high yielding varieties in ginger.
