“…Similarly, different agronomic managements and development of new plant types are recommended to meet the main challenges of chickpea adaptation to stresses ( Vadez et al, 2021 ). A significant positive correlation with grain yield, high heritability coupled with high genetic variability and less yield losses under optimal conditions are essential for a character to be expressed as drought tolerance marker ( Maqbool et al, 2017 , Chandora et al, 2020 ). Therefore, a comprehensive multiple enhancement approach is needed for sustainable crop production under drought stress ( Arif et al, 2021 ).…”

Drought is a major and constantly increasing abiotic stress factor, thus limiting chickpea production. Like other crops, Kabuli Chickpea genotypes are screened for drought stress through Multi-environment trials (METs). Although, METs analysis is generally executed taking into account only one trait, which provides less significant reliability for the recommendation of genotypes as compared to multi trait-based analysis. Multi trait-based analysis could be used to recommend genotypes across diverse environments. Hence, current research was conducted for selection of superior genotypes through multi-trait stability index (MTSI) by using mixed and fixed effect models under six diverse environments. The genotypic stability was computed for all traits individually using the weighted average of absolute scores from the singular value decomposition of the matrix of best linear unbiased predictions for the genotype vs environment interaction (GEI) effects produced by a linear mixed-effect model index. A superiority index, WAASBY was measured to reflect the MPS (Mean performance and stability). The selection differential for the WAASBY index was 11.2%, 18.49% and 23.30% for grain yield (GY), primary branches per plant (PBP) and Stomatal Conductance (STOMA) respectively. Positive selection differential (0.80% ≤ selection differential ≤ 13.00%) were examined for traits averaged desired to be increased and negative (-0.57% ≤ selection differential ≤ -0.23%) for those traits desired to be reduced. The MTSI may be valuable to the plant breeders for the selection of genotypes based on many characters as being strong and simple selection process. Analysis of MTSI for multiple environments revealed that, the genotypes G20, G86, G31, G28, G116, G12, G105, G45, G50, G10, G30, G117, G81, G48, G85, G17, G32, G4, and G37 were the most stable and high yielding out of 120 chickpea genotypes, probably due to high MPS of selected traits under various environments. It is concluded that identified traits can be utilized as genitors in hybridization programs for the development of drought tolerant Kabuli Chickpea breeding material.

“…The major chickpea growing zones of Ethiopia are South Gondar, North Gondar, East Gojam, West Gojam, North Shewa, East Shewa, West Shewa, South Wollo, North Wollo, and Tigray [9]. In Ethiopia, there are about 1173 chickpea accessions collected from different agroecologies and geographical origins and stored at the Institute of Biodiversity and Conservation [10]. Although Ethiopia is bestowed with diverse agroecologies and, especially, crop diversity, the productivity of chickpea is about 850 kg/ha [7] due to the exposure of the crop to several biotic and abiotic stresses.…”

Molecular Genetic Diversity and Population Structure in Ethiopian Chickpea Germplasm Accessions

Chickpea (Cicer arietinum L.) is a cheap source of protein and rich in minerals for people living in developing countries. In order to assess the existing molecular genetic diversity and determine population structures in selected Ethiopian chickpea germplasm accessions (118), a set of 46 simple sequence repeat (SSR) markers equally distributed on the chickpea genome were genotyped. A total of 572 alleles were detected from 46 SSR markers, and the number of alleles per locus varied from 2 (ICCM0289) to 28 (TA22). The average number of alleles per locus, polymorphism information content, and expected heterozygosity were 12, 0.684, and 0.699, respectively. Phylogenetic analysis grouped the 118 chickpea genotypes from diverse sources into three evolutionary and/or biological groups (improved desi, improved kabuli, and landraces). The population structure analysis revealed six sub-populations from 118 chickpea genotypes studied. AMOVA revealed that 57%, 29%, and 14% of the total genetic variations were observed among individuals, within populations, and among populations. The insights into the genetic diversity at molecular levels in the Ethiopian germplasm lines can be used for designing conservation strategies as well as the diverse germplasm lines identified in this study can be used for trait dissection and trait improvement.

“…More precisely south-eastern Turkey and adjoining Syria are considered as the centre of origin of the crop [ 2 , 3 ]. Chickpea is cultivated mainly in arid and semi-arid areas of more than 50 countries across Asia, Africa, Europe, Australia, North America and South America [ 4 ]. Globally 17.2 million tonnes of chickpea is produced from ca.…”
