Variabilitas Genetik dan Heritabilitas 20 Genotipe Tanaman Cabai (Capsicum annuum L.) Unggul Koleksi Ipb
Abstract: Study lasted from
June until November 2011, at Bogor Agricultural University (IPB), Leuwikopo,
Dramaga. This research using Randomized Complete Block Design (RCBD), one
factor consisting of 20 genotypes of chilli that comes from the collection of
IPB (C2, C5, C105, C111, C117, C118, C120, C160, C51, F5110005-91-13-5,
F5110005-91-13-12, C157, C159, F5120005-5-11-1, F8002005-2-9-12-1, C140, C19,
C18, C143, C145) with three replications. Data were analyzed using the F test
and test of Duncan New’s Multiple Range Test (DNMRT) 5% level. Result shows
that the genetic variability and heritabilty of 20 genotypes chilli in
quantitative parameters were different each other.Genotypic coeffecients of
variation (GCV) at intervals between 1,36 -22,11%. The heritability value at
intervals 42.05%-91.80%. Almost all of the observed variables had high
heritability value, except leaf length and flowering date which is only on
intermediate criteria. For weight per fruit, C143 reveal significant value than
other genotype and yield per plant C5 reveal significant value than the others.
It indicate that C143 and C5 can be selected as Hybrid chilli plant. The
genotypes tested in this study had a high level of variability that could
potentially be used as a parent for crosses. Meanwhile, the 20 genotypes that
observed qualitiatively shows it genetic relationship.
