Abstract/ Executive Summary:

Twenty four CIMMYT developed normal and QPM hybrids along with one local hybrid were evaluated at three locations test the performance of hybrids over locations and to select better performing hybrid(s) having higher yield potentiality. Results indicated the presence of significant variation among the tested entries for the characters under studied viz. grain yield, days to silkiest, days to maturity, plant height and ear height. Considering overall performance four hybrids namely CMS033002, CMS 983002, CMS 033010 and CMS 033016 could be selected as promising materials.

Keywords: QPM, HYV, variation

Location: Joydebpur, Ishurdi and Jamalpur under BARI

Start Date: 00-00-2005

End Date: 00-00-2006

Program Area: Variety and Species

Commodity: Maize

Objectives:

To select higher yielding hybrids, under Bangladesh condition.

Methodology:

The experiment was conducted at Joydebpur, Ishurdi and Jamalpur during rabi, 2005-06. Twety four CIMMYT developed normal and QPM hybrids and one local check Variety BHM-3 were evaluated in this study. Experimental seeds were sown on 25^th November, 2^nd December and 12^th December 2005, respectively, at Joydebpur, Ishurdi and Jamalpur in alpha lattice design with three replications. The unit plot size was maintained at 5.0 x 1.5m. Spacing was 75 x 20cm between row to row and hill to hill, respectively. After seedling emergence one healthy plant per hill was kept. Fertilizers were applied @ 250, 120, 120, 40 and 5kg/ha of N, P₂O₅, K₂0, S and Zn, respectively. All other intercultural operations were done according to the necessity. Data on yield and other morphological characters were recorded on whole plot basis. Plot yield was converted to t/ha for convenience. Statistical analyses were done using MSTAT programme.
