Pendugaan Parameter Genetik Populasi Cabai (Capsicum annuum L.) Melalui Pengujian F1 Hasil Persilangan Secara Diallel
Abstract: The objective of
this research were to estimate genetic parameters such as variability,
heritability, general combining ability (GCA), and specific combining ability
(SCA), of various agronomic traits in
chili population through diallel cross. The research was arranged in a
randomized complete block design in which 15 hybrids genotypes created by half
diallel cross were evaluated with three replications. Seedlings of twenty eight
days old was transplanted to a plot of 1 m x 5 m with planting space of 50 x 50
cm. Ten samples were chosen from each plot to obtain plant height, height of stem dichotomous,
weight per fruit, fruit length, fruit rind thickness, fruit diameter and fruit
weight per plant. Data analyses were performed by analyses of variance and then
translated to genetic parameters following the Griffing’s methods model IV. The
results indicated that the value of GCA and SCA were significant for several
characters but not for others. Due to its suitable GCA value, one genotype such
as C5 may be selected as one parent to improve agronomic characters such as
hastening days to flower and harvest,
increased stem diameter, thick
fruit pulp, fruit diameter, weight per fruit, and fruit weight per plant.
Genotypes C120xC5 and C111xC19 may be utilized to improve stem diameter, thick
fruit pulp, fruit diameter, weight per fruit, and fruit weight per plant.
Heritability were significant for stem height,
dichotomous, stem diameter, fruit length, fruit flesh thickness, fruit
diameter, total number of fruits per plant, and fruit weight per plant. Fruit
rind thickness, fruit diameter, weight per fruit, and total number of fruits
per plant was positively correlated to total fruit weight per plant.
