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...

With the objective of accelerating genetic understanding and crop improvement through genomics-assisted breeding, a draft genome sequence has been assembled for the CDC Frontier variety. In this context, 544.73 Mb of sequence data were assembled, capturing of 73.8% of the genome in scaffolds. In addition, large-scale genomic resources including several thousand simple sequence repeats and several million single nucleotide polymorphisms, high-density diversity array technology (15 360 clones) and Illumina GoldenGate assay genotyping platforms, high-density genetic maps and transcriptome assemblies have been developed. In parallel, by using linkage mapping approach, one genomic region harbouring quantitative trait loci for several drought tolerance traits has been identified and successfully introgressed in three leading chickpea varieties (e.g. JG 11, Chefe, KAK...

Pulses are significant parts of the diet for Ethiopians particularly of the more than 50 million Christians who do animal byproduct fasting for a long period (180-250 days a year). The per capita of legume produce is about 25kg/person and about 3/5th of produce goes for consumption, while the rest is used for marketing and seed resources. In the marking of the five decades of legumes improvement in Ethiopian, return to breeding investment ultimately have remained on an increase as we have been able to witness yield, price, nutritional quality and market avenue revamping in the due courses (Erana and Fatih, 2020). The breeding approaches have been evolved from simple accession variability assessment for diversity of originated legumes through genetic recombinant evaluation and to marker assisted approaches. A robust diversity resource development panel have already been established where hundreds of F1 recombinants enabled to evaluate thousands of subsequent filial generations, giving an opportunity of ultra super lines identification in the increasingly stiff competition for surpassing preceding cultivars with trait of interests. Ethiopia is secondary center of diversity for several legumes including Vicia, Pisum, Cicer, Lens, Lathyrus, Trigonella and Vigna. Trait converging varieties or so called products have changed in description and qualification as market derives the game. In Ethiopia, legumes constitute a critical component of the agricultural system in Ethiopia; about 12 legume economic crops classified as beans, peas and other clusters are principally grown in the country. Of these, faba bean (horse bean) (Vicia faba L.), field pea (Pisum sativum L.), chickpea (Cicer arietinum L.), lentil (Lens cultinaris Medik.), grass pea (Lathyrus sativus L.), fenugreek (Trigonella foenum-graecum L.) and lupine (Lupinus albus L.) are categorized as highland legume crops and grown in the cooler highlands. On the other hand, common bean (haricotbean) (Phaseolus vulgaris L.), soya bean (Glycine max L.), cowpea (Vigna unguiculata L.), pigeon pea (Cajanus cajan L.) and mung beans (Vigna radiata L.). are categorized as lowland legume crops and predominantly grown in the warmer and low land parts of Ethiopia (CSA, 2018; Getachew, 2019; Tegegne, 2017; Yirga et al, 2010). Dekoko (Pisum sativum var. abyssinicum) is a unique ecotype produced in niche of ecological adaptation and tradition.

The agronomic traits evaluated and tested were stand count at initial, days to flowering, days to maturity, plant height, and stand count at harvest, seeds per pod, seeds per plant, wilt score, hundred seed weight and usable grain yield per hectare. The evaluated materials showed three maturity class i.e. early, medium, and long durations. Among the tested materials, ICEAP-00557 scored the highest grain yield (2349kg/ha), followed by ICEAP-00576-1 (1737kg/ha), however, the standard check ICEAP-87091 score was comparatively inferior (1390kg/ha).

Thus, it was suggested the existence of sufficient variability for key economic yield that gives an option for promoting for high socioeconomic performance through adaptation and commercialization.
