ABDILLAH: Variability and Heritability some character a corn (Zea mays L) result selfing of second generation. Supervised by JENIMAR AND LUTHFI A.M SIREGAR. The objective of the research was to valuate variabilities of several characters affected by the genotype (σ2g), the interraction between genotype and environment (σ2p), studied heritability and also to see the effect resiprocal breeding of F2 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 F2 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, age of blooms male, the number of kernel per ear, the weight of kernel per ear, and fast of charging seed. From progeny test some character of genotype show the characteristis of one kind . Phenotype variability all characters showed range wide variability, and Ghenotipe variability all characters showed range pressed variability, heritability of plant’s height, age of blooms male, the number of kernel per ear, the weight of kernel per ear, and fast of charging seed were medium. 060307004
