Abstract/ Executive Summary:

Forty one CIMMYT developed hybrids along with four cheeks were evaluated to test the performance of hybrids to select better performing one(s) having higher yield potentiality. Significant variation was found for all the character among the hybrid. Considering yield and other yield contributing characters hybrid E18 and E32 were found promising.

Keywords: Evaluation, Mapping test, Hybrid, Maize

Location: BARI, Joydebpur

Start Date: 00-00-2012

End Date: 00-00-2013

Program Area: Variety and Species

Commodity: Maize

Objectives:

To test the performance of CIMMYT developed hybrids and select better one (s).

Methodology:

The experiment was conducted at BARI, Joydebpur during rabi 2012-13. Forty one CIMMYT developed hybrids and four check varieties were evaluated in this trial. Seeds were sown on 17 January 2013. The experiment was laid out in alpha lattice with 2 replications. Seed of each entry were sown in 1 row, 3 m long plot with 60 cm and 20 cm spacing between row and plant, respectively. Fertilizers were applied @ 250, 120, 120, 40 and 5 Kg/ha of N, P₂O₅, K₂O, S and Zn, respectively. All intercultural operations were done as and when necessary. Data on yield and other desirable characters were recorded on whole plot basis. Plot yield was adjusted to moisture percentage and optimum plant number and it was converted to t/ha for convenience. All data were processed and analyzed using Crop stat 6.1 program.
