All the genotypes were grouped in to seven clusters. Cluster-I having the largest genotype (i.e eighteen genotypes), Cluster-II having six genotypes, Cluster-IV having four genotypes and Cluster-III, V, VI and VII having one genotype each. The maximum inter-cluster distance was observed for cluster between II & IV (262.94) followed by cluster II & III (169.20) and cluster II & V (144.90) indicating that the genotypes of these clusters might be differing marginally in their genetic architecture. The maximum contribution towards divergence was observed by Plant height (56 %) followed by Days to 50 % Flowering (18.75 %), Leaf /Stem ratio (15.24 %), Crude protein (12.38 %), Green Fodder Yield (3.02 %) and Dry matter yield (q/ha/day) (1.61 %). The genotypes MAH 15-84, IFH 10-21 K2, ADFM-4 and KDFM-8 were the most promising ones and their adaptation to the agro-ecological condition of Jharkhand. This can bring substantial increase in green fodder yield and crude protein (%). This study gives an insight into the diversity pattern of advance maize lines which will be helpful for further utilisation in breeding programme.
