The objectives of the research was valuated variability of some characters caused by genotype effect (σ2g), genotype and environment intraction (σ2p), studied heritability and also to see the effect resiprocal breeding of F1 with it’s parents of corn (Zea mays L.). The experiment was conduced at exprimental field Faculty of Agricultural, North Sumatera University, Medan. with altitude ± 25 meters above sea level from Januari to April 2009, used Randomized Block Design with one factor and four replication, there is F1 from Arjuna X Sukmaraga, Sukmaraga X Arjuna, Lamuru X Kalingga, Kalingga X Lamuru, Srikandi kuning X Bayu dan Bayu X Srikandi kuning. The result of the research is genotype have significantly effect with plant’s height 2-7 weeks after planting, leaf’s number 6-7 weeks after planting, age of blooms male, age of blooms female, age of harvesting, the number of kernel per ear, the weight of kernel per ear, the weight of 100 kernel and the net of product per plot. From progeny test some character of genotype showed better of some character and maternal effect. Phenotype variability all characters showed range wide variability, heritability of plant’s height, age of blooms female, age of harvesting and weight of 100 kernel were height and genetik variability were showed wide range so selection will be effective at character than another character.
