| dc.description | Maize (Zea mays L) is one of the most important cereal crops of the world. It belongs to the
family Gramineae and is a photo-insensitive, cross pollinated C, crop. It is one of the
promising cereal crops and ranks 3“ both in acreage and production in Bangladesh. Maize
grains have high nutritive values and used as food, fodder, feed and fuel. Its demand is
increasing day by day. Maize is being cultivated all over the wor|d but the yield of maize is
low in Bangladesh as ¢ompared to other maize growing countries. The area of maize
cultivation increased to 0.14 million hectare in 2006 from 0.09 million hectare in 2005. In the
FY2004-2005, maize production estimated by DAE was about 0.47 million metric tons, that
particularly compensated the short fall in wheat production (Bangladesh Food Situation
Report, 2005.). | en_US |
| dc.description.abstract | A field experiment was conducted at Hajee Mohammad Danesh Science and Technology
University, Dinajpur, Bangladesh, at the experimental plot of the Department of Genetics and
Plant Breeding during the Kharif season of 2008 to study on the hybrid performance of
different maize hybrids. A larger variation in plant characters and yield performance among
the hybrids was noticed. The hybrids MH7 and MHz. produced maximum grain yield per
plant (187.2 g ) which was identical with MH; and MHz, ( 186.7 and 186.2 g respectively)
while MHz; was the minimum in this respect having minimum grain yield per plant (129.2 g)
and was also identical with the Check (MH39 and MHyo). Phenotypic variance against yield
per plant (371.79) was higher than the genotypic variance (172.94). This indicated the
existence of much influence of environment on the expressivity of the character. This
character showed moderate genotypic (8.43) as well as phenotypic (12.35) co-efficient of
variation associated with low heritability (46.52 %).
The range of standard heterosis over the check variety was -1.657 to 21.55 percent for the
hybrids MH37 and MHs3po, respectively. In case of grain yield per plant, significant positive
heterosis was desirable and the hybrids MHs, MH7, MHis, MHic6, MHi7, MHis. MHi9, MH2.
and MH» showed significantly positive heterosis over the check variety. Apparently positive
heterosis.on grain yield per plant was desirable and 8 hybrids showed significant and positive
result. The highest positive heterosis was obtained in the hybrid MH7and was scored |. | en_US |
