Genotype-Environment Interaction and Genetic Parameters in Chickpea (Cicer arietinum L.) Landraces

Hayel ALwawi, Mohammad Moulla, Wafaa Choumane


In order to determine the desirable line for chickpea rainfed sowing, seven local lines (K- 6, G- 35, D- 15, F-20, B -17,
H- 45 and M- 20) were selected from Syrian chickpea landraces. These lines were grown during two seasons 2006 /
2007- 2007 / 2008 at two different locations (Tal-sandal: with a mean annual precipitation of 475mm, Harran: with a
mean annual precipitation of only 300 mm). Genotype-environment interaction and genetic parameter were studied for
seed yield per plant /g, days to maturity and protein content.
The results showed that effect of location (L) and season (E) was highly significant (P < 0.01) while the interaction
among Locations, Seasons and Genotypes ( L x E x G) was not significant (P > 0.05).
The heritability for protein content varied from (0.83) to (0.93) that indicated the presence of a considerable proportion
of total variability due to genetic causes. A high genetic advance (GA) (51.5 to 62.7) % was achieved for seeds yield per
plant. The environmental variance (?2e) was very low for days to maturity and protein content. The differences between
genotypic (GCV) and phenotypic (PCV) coefficient of variability were very small.
The results recommended to selection line M-20 that was the desirable line for both seed yield per plant (33 to 40) g and
protein content (22.17 to 24.72%) as compared to other lines.
