Abstract
Background: Maize is one of most important cereal crop in world after wheat and rice. It is
grown in Pakistan as a major cash crop cultivation in the area of 1083 thousand hectares
producing 3990 thousand tones. Maize is dual propose crop it is used as feed for livestock
and food for human. It is also used as a raw material in textile, food and medicine industries.
The present study was conducted to evaluate parents and F1 hybrids of maize for seedling
traits including heritability, heterosis and heterobelteiosis.
Methodology: The genetic material was comprised of twelve parents and including their 36
F1 hybrids. The parents and F1 hybrids were sown in the iron treys filled with sand in three
replications following completely randomized design. The data was recorded for fresh root
length, fresh shoot length, fresh root-to-shoot length ratio, fresh root weight, fresh shoot
weight and fresh root-to-shoot weight ratio. The data was subjected for analysis genotypic
and phenotypic coefficients of variance. The genetic advance was calculated by using
Falconer (1989) formula.
Results: The average batter performance was given by B-336, EV-347, EV-1097Q and B327. The F1 hybrids, EV-1097Q × EV-347, EV-1097Q × EV-340, Raka-poshi × EV-347, B327 × B-316 and Sh-139 × EV-347 showed higher values of heterosis and heterobeltiosis for
respected studied traits of maize seedlings.
Conclusion: In this study, it is concluded that the F1 hybrids, EV-1097Q x EV-347, EV1097Q x EV-340, Raka-poshi x EV-347, B-327 x B-316 and Sh-139 x EV-347 may be used
as higher yield maize hybrids and parents EV-347, EV-1097Q, B-327 and B-316 may be used
to develop higher yield maize hybrids following heterosis breeding scheme.
