Heterosis studies in maize (Zea mays L.) for grain yield and its attributes

Niranjan Kumar Chaurasia, RBP Nirala, Raj Kishor Roy and Jai Prakash Yadav
Present investigation was carried out in Kharif 2019 at Experimental Farm, Bhola Paswan Shastri Agricultural College, Purnea, Bihar Agricultural University, Sabour with seven parental inbred lines and their twenty one F1’s generated through half diallel matting scheme during Rabi, 2018-19. The experiment was performed in randomized block design with three replications. Analysis of variance for Randomized Block Design (RBD) revealed the mean squares due to genotypes were highly significant for all the fourteen quantitative characters namely days to anthesis, days to sulk, anthesis-silking interval, days to 50 per cent physiological maturity, plant height, ear height, ear diameter, kernel rows per ear, kernels per row, grains per plant, 1000-kernel weight, shelling per cent and grain yield per plant except ear length. The estimates of standard heterosis over the best check, DMRH-1308 for grain yield per plant and its attributes revealed the only one cross combination among twenty one, namely P5 x P7exhibited highly significant positive standard heterosis was considered as promising experimental hybrids and may be exploited commercially after critical evaluation for their superior and stable performance over environments.
