“…At Mata, genotype, DZ-2012-CK-20113-2-0042 was the best performer as in Alaku Belle and the performance of the local variety was the poorest in a similar fashion it displayed in Shambu and Hawa Galan (Table 4). This result is in agreement with the report of Getachew et al (2015) who showed inconsistent performances of chickpea genotypes in central and eastern Ethiopia.…”

Currently, 40% of arable land in Ethiopia is affected by acidity and particularly the soil acidity problem that occurs in central and western zones of Oromia deserves immediate intervention for crop production. The objective of the present study was to examine responses of Desi type chickpea varieties against acidic soil of western Ethiopia. Pooled analysis of variance (ANOVA) indicated significant difference among genotypes indicating differential response of chickpea genotypes to acidic soil. The combined mean of genotypes indicates that Natoli and DZ-2012-CK-20113-2-0042 were top yielders. Differential response of chickpea genotypes indicates the possibilities of designing better chickpea breeding strategies that aim at screening large germplasms of chickpea genotypes for soil acidity tolerance and thereby developing a cultivar(s) with wider adaptations.

“…The AMMI stability (ASV) value is the distance from zero in a bi-plot between the IPCA 1 scores and the IPCA 2 scores (Getachew et al, 2015). In the AMMI analysis, the IPCA 1 score contributes more to the genotypeenvironment (GE) interaction sum of squares.…”

Chickpea is the major pulse crop cultivated in Ethiopia. However, its production is constrained due to genotype instability and environmental variability. This research was carried out to examine the magnitude of environmental effect on yield of chickpea genotypes and to investigate the stability and adaptability of genotypes under different agro-ecologies. Twelve genotypes evaluated in randomized complete block design with three replications in three locations for two continuative years. Various stability indices used to assess stability and genotype by environment performances. Combined analysis of variance for yield and yield components revealed highly significant (P≤0.01) differences for genotypes, environments and their interaction. Growing years do not show difference. The significant interaction showed genotypes respond differently across environments. At Guduru, Hareto and Gitilo, top performing genotype in grain yield were genotype 229961 (2.33ton/ha), genotype 225887 (3.6ton/ha), and genotype 225887 (2.23/ha), respectively. The first two principal components (PC1 and PC2), which were used to create a two-dimensional bi-plot, explained 7.5 and 3.75% of AMMI sum of squares, respectively. Hareto and Guduru are the most differentiating environments, while Gitilo is more responsive environment than the other environments since it is far away from the other in altitude. Genotype 212476 and 212976 were the most stable as well as productive at Hreto environment, genotype 229961 and 225887 were the most stable as well as productive at Guduru environment. Genotype 229959 and 215189 were stable with intermediate productive in both years and at three of the growing locations. Genotype 219804 and 225889 are less responsive. The best genotypes with respect to Guduru site are 229959 and 215189: the best genotype for environments with respect to Hareto was 212476 and 212976, and to Gitilo environment 229961 and 225887 genotypes.

“…Mean, range and coefficient of variation of agronomic traits have been widely used to determine the variations available in the population. Moreover, the values of genotypic and phenotypic coefficient of variations, >20%, 10 to 20% and <10% are considered to be higher, intermediate and lower respectively (Getachew et al, 2015). The effectiveness of selection in any crop depends on the extent and nature of phenotypic and genotypic variability present in different agronomic traits found in the population (Arora, 1991;Keneni et al, 2011).…”

“…Rehman et al (1996) and Wahid and Ahmed (1999) reported high estimate of genetic coefficient of variability for plant height and seeds per pod. Getachew et al (2015) reported high genetic coefficients of variability for seeds per plant and seed yield per plant. High genotypic coefficient of variation indicated the availability of high genetic variation for selection and improvement; while the lower value indicated that selection is not effective for particular character because of the narrow genetic variability (Singh et al, 2003;Upadhaya et al, 2008;Mullualem et al, 2017;Shiferaw et al, 2017).…”

This research aim to assess morphological diversity of the elite chickpea (Cicer arietinum L.) varieties in Ethiopia. Nineteen elite varieties of chickpea in Ethiopia were used to analyze the means and components of variability (genetic, phenotypic and environmental), and interrelationships (genetic and phenotypic) for yield and various other yield components. Such nineteen varieties were planted by the technique of Randomized Complete Block Design (RCBD) and three replications were used. Each genotype was sown in four rows with 4.8 m 2 (1 m x 4.8 m) plots area, with 40 cm and 1 m spacing between plots and blocks, respectively. In each plot, one hundred and sixty seeds were planted, using 10 cm spacing between plants These nineteen elite varieties of chickpea were evaluated for the traits of hundred seed weight, biological yield, grain yield, plant height, days to 50% flowering, number of primary branches, number of secondary branches, number of pods per plant, number of seeds per plant, harvest index and days to 90% maturity. Genetic variations were evident among released chickpea cultivars as confirmed by high phenotypic and genotypic variations for quantitative and qualitative traits. Analysis of variance revealed significant differences among the genotypes for all the characters except hundred seeds weight, days of 50% flowering and grain yield. Strong and positive significant correlation was observed between grain yield, biological yield, number of seeds per plant, number of pods per plant and number of primary branches; showing that their improvement led to yield improvement in chickpea. The result suggested from the mean values of number of seeds per plant, number of pods per plant and days of maturity that chickpea genotypes ICCV-14808, Mariye and ICCV-92069 may be used as parents in further breeding program to develop high yielding cultivars. Principal component analysis revealed that quantitative traits contributed a lot to chickpea genetic variability.
