ABSTRACT
This study aimed to estimate the genetic variability, heritability, and components
of production traits in closely related populations of open-pollinated corn (Zea
mays L.). The research was conducted experimentally using a randomized block
design with four half-sib families and four replications. Observed traits included
male and female flowering age, harvest age, cob weight without husk, cob length
without husk, number of seed rows per cob, number of seeds per plant, number of
seeds per row, seed weight per cob, seed weight per plant, and 100-seed weight.
Data were analyzed using SAS Version 9.04, and genetic components were
determined using Hallauer et al.'s (2010) method. Results showed that harvest age,
cob weight without husk, cob length without husk, number of seed rows per cob,
number of seeds per plant, number of seeds per row, seed weight per cob, and
seed weight per plant had significant mean squares between and within half-sib
families. Broad-sense heritability was high for harvest age, cob length without
husk, number of seed rows per cob, number of seeds per plant, number of seeds
per row, seed weight per cob, and seed weight per plant. Narrow-sense heritability
was moderate for these traits, except for male flowering age, which had low
heritability. Genetic variability was narrow for all traits across the four half-sib
families, except for seed weight per cob and seed weight per plant in the HS3
population, which showed high variability.
Keywords: genetic variability, heritability, half-sib family, open-pollinated
variety.
