Abstract
This research analyses the level of genetic variability, heritability
and relationships between important oil properties in lemongrass (Cymbopogon
spp.) in semi-arid weather. Twelve genotypes were evaluated based on the
content of essential oils, bit-carboxyl and germanol capacity, and morphology.
Genetic parameters such as the genotypic (s2g) and phenotypic variance (s2p)
and the genotypic coefficients of variations (GC-V) and phenotypic coefficients
of variations (PC V), broad-sense heritability (H2) and the genetic advance
(GA) were obtained to gain an insight into the possibilities of genetic gain.
Hydrodistillation was used to examine the essential oil composition and
quantified the product using a spectranalyzer, and the compositional validation
and chemotype classifications were by the use of gas chromatography-mass
spectrometry (GC-MS). The analysis of correlations and path analyses, found out
that there are significant positive relationships between the citral content
and the oil yield implying that high citral concentration could be selected
with the objective of improving quality and quantity of oils. Principal
component as well as cluster analysis distinguished the genotypes into three
chemotypic groups. The results are very crucial in future breeding and selection
of lemongrass varieties which are high-oiled and high-citral with adaptation to
semi-arid ecosystems.
