ABSTRACT

Fifteen maize (Zea mays L.) genotypes were evaluated for Genetic Diversity Studies at Forage Research Farm, RVC, Birsa Agriculture University, Ranchi. The Experiment was laid out in RBD with three replications. The genotypes were significantly different for all the characters, this indicates that there is scope for further genetic studies. All the genotypes were grouped in to four clusters. Cluster-I having the largest genotype (i.e seven genotypes), Cluster-IV having four genotypes, Cluster-II having three genotypes and Cluster-I having one genotype. The maximum contribution towards divergence was observed by Dry matter yield (49.52 %) followed by leaf /stem ratio (15.24 %), Crude protein (12.38 %), Dry matter yield (q/ha/day) (11.43 %), Days to 50 % flowering (9.95 %). The genotypes DMRH-1140, IIMRFH-17-1 and IMH-1527 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 (%).
