Genotype X Environment Interaction and Stability Analysis for Yield and Yield Related Traits of Desi-Type Chickpea (Cicer Arietinum L.) In Ethiopia

Abstract

Chickpea is the major pulses grown in Ethiopia DZ-2012-CK-0040, DZ-2012-CK-0036 and DZ-2012-CK-0040, DZ-2012 and variety Natoli were recommended as specifically adapted to sites Akaki, Chefe Donsa, Debre Zeit, Dembia and Haramaya respectively.

Assessment of Genetic Variability and Yield Stability in Chickpea Genotypes under Diverse Environments

“…The predominance of linear component would help in predicting the performance of genotypes across environments. This also suggested that prediction for these attributes would be perfect, these results supporting the earlier findings of Hasan et al, (2008), Segherloo et al, (2008), Alwawi, Choumane (2010) and Tilahun et al, (2015). The genotypes had regression coefficient lesser than unity coupled with mean values less to grand mean revealed that above average stability of genotypes.…”

Genetic variability, character association and coheritability for yield traits over the locations in chickpea (Cicer arietinum L.)

“…These results were in general agreement with the findings reported by Johnson et al (2018), Sharma and Johnson (2017), Rao (2011), Shivani and Sreelakshmi (2015), Tilahun et al (2015), Johnson et al (2015), Yadav et al (2010), Yadav et al (2014), Rao and Rao (2014) and Johnson et al (2016).…”

“…The Chickpea crop shows differential performance when grown under different environments after the harvest of rice. Environmental factors such as soil moisture, sowing time, fertility and temperature and day length have strong influence during various stages of plant growth (Tilahun et al, 2015). The environment is changing day-by-day and this implies that it is necessary to evaluate crop genotypes at different environments or agro-climatic zones to assess their real performances.…”

Genotype × Environment interactioon in Chickpea (Cicer arietinum L.) under Afghanistan environments and identification of high yielding genotypes

“…Each of these genotypes yielded 0.5 t ha -1 over the average on the respective location. These genotypes also yielded the highest in the associated environments in the GGE bi-plots (Figures 2 and 3 Kan et al (2010) on the stable genotypes yielding higher than the general average, and Tilahun et al (2015) for genotypic performance based on average across the locations involved. …”

“…Graphical tools for identification of mega-environments and specifically adapted genotypes are presented in Yan et al, (2000) and Yan (2011). In neighboring Iranian environments, an analysis of genotype by environment data was carried out to examine the nature of genotype by environmental interaction in chickpea by Farshadfar et al, (2011).While several studies to evaluate GEI in chickpea have been reported for environments in many countries (Bakhsh et al, 2011;Singh et al, 1990;Bozoglu & Gulumser, 2000;Farshadfar et al, 2011;Imtiaz et al, 2013;Tilahun et al, 2015), but such an evaluation is not available for chickpea growing environments in Afghanistan.…”
