Genetic Analysis of Maize ( Zea mays L.) Genotypes for Baby Corn, Green Ear and Grain Yield

Most maize cultivars have been developed for grain production. Considering the diversified uses of maize, interest has been demonstrated for the evaluation of maize hybrids with regard to their baby corn, green ear and grain yield production ability. In the present work seventeen corn cultivars were evaluated in the yield of baby corn, green ears and dry grains. Two experiments were carried out in the same season, in neighboring areas and managed in a similar way in Birsa Agricultural University, Ranchi, Jharkhand, India in a randomized blocks design with three replicates. Baby corn yield was evaluated in one of the experiments. The other experiment was set to evaluate green ear and dry grain yield. The inbreds BQPM-4 and BAU1M-4 were found to be the most productive with respect to the weight of marketable husked and unhusked baby corn ears. The inbreds BAU1M-4 and BQPM-2 were the most productive with respect to number and weight of marketable husked green ears and grain yield. Therefore, the cultivars differ with each other when different corn exploiting purposes are taken into account.
