In order to achieve more high- yielding chickpea genotypes than the existing cultivars that have suitable traits such as seed yield, more number of pods per plant, coarseness of seeds , early maturity and other desired agricultural traits, 16 advanced chickpea genotypes selected from advanced tests comparing crop year yield 2015-2016 along with Adel and Azad witness figures for three crop years (2016-2019) in Gachsaran, Gonbad, Khoramabad and Ilam were planted in the form of a completerandomized block design with three replications. Composite variance analysis showed a significant effect of genotype, environment and genotype interaction in the environment (GEI)., Therefore, Biplot method was used to analyze the genotype × environment interaction. The first two principal components explained 32/50 percent (26.12 and 24.2%, respectively) of the total GEI changes. The polygon view of Biplot showed that genotypes 18, 9, 17 and 16 with higher than average performance and near the origin of Bioplate were genotypes with high general stablity. Also genotypes 5, 12 and 11 showed adaptation to many environments. The average tester view of Biplot also showed that genotypes 12, 18 and 9 were the closest genotypes to the ATC axis and therefore the most stable and also had high average yield in different environments. The ideal genotype view of Biplot showed that genotypes 5 and 12 at the closest distance from the Biplot origin were the best genotypes and genotypes 1, 2 and 13 were the most unfavorable genotypes in terms of seed stability and yield.According to the results, genotypes 5, 9, 12 and 16 were selected as promising genotypes and candidates for introduction.

Chickpea is the second most important pulses in arid and semi-arid regions of the world. This product is often cultivated as rainfed crop, so drought stress causing 50% yield loss. In this research, 11 SSR and 6 CAPS primer pairs were used to evaluate genetic variation among 9 chickpea candidate genotypes for drought tolerant and 2 common sensitive cultivars. Ten effective SSRs were again evaluated in a population containing random genotypes for cold-tolerance. SRR band analysis in final experiment generated 40 alleles, of which 37 were polymorphic. The average number of polymorphic alleles for each gene site was 3.9 with the range of 2-9 alleles. The polymorphic information content (PIC) varied from 0.21 to 0.85. The cluster analysis, based on the UPGMA algorithm and Jaccard's similarity coefficient, splited the genotypes into nine distinct groups including four groups of drought tolerant genotypes, two relatively drought tolerant groups and other three groups belonging to the random population. The polymorphism results of the SSR and CAPS markers indicated that the two genotypes MCC544 and MCC392 were more distinctive from other drought tolerant genotypes. MCC537 and MCC696 were also highly related in a separate group, and the MCC80 was allocated in average position among tolerant genotypes. MCC427 and a common cultivar MCC358 were classified into one group as well as the international cultivar MCC252 with MCC302 genotypes. The results indicated the lack of a genetic similarity between selected population of drought tolerant candidates and cold tolerant candidates. This could indicate that there might be no pleiotropic effect among the genes involved in these stresses, which can be important for breeding purposes of this crop.

Histamine, an important biogenic amine, is produced by many organisms and play a diverse role in living organisms. Many micro-organisms synthesis and stored histamine in food, especially in canned food products, posing health threat to human. Diamine oxidase or histaminase catalysis histamine in healthy individuals and reduces its harmful side effects. In this study, a full-length cDNA encoding an amine oxidase was isolated from a chickpea (Cicer arietinum) landrace (grit), deposited in Genbank database (KU058599) and cloned in a binary expression vector. The cloned cDNA had an ORF with 2013 bp length encoding a protein with 670 amino acids and a molecular mass of 75.7 KDa. Multiple sequence alignments analysis showed that the active site and important amino acids are highly conserved in E.coli, pea and grit histaminases. Bioinformatics analysis revealed differences in 4 amino acids between grit histaminase and that of GenBank deposited Cicer arietinum amine oxidase (CAA08855). Phylogenetic analysis grouped grit histaminase (KU058599) with plant, especially legume histaminases with 99% bootstrapping.

Water deficit is the most important abiotic stress limiting crop productivity in most arid and semi-arid areas of the world and Iran. In order to achieve precise experimental comparisons, the response of chickpea genotypes MCC508 and MCC 521 to water deficit was evaluated and then expression of the genes assessed under the same stress situation. Decreasing trend of Relative Water Content (RWC) was significantly less in MCC508 compared with MCC521, especially after 24 hours (p≤0.05). Membrane Stability Index (MSI) was also higher in MCC508 whereas electrolyte leakage and Malondialdehyde (MDA) accumulation were almost stable but increased 1.2-fold relative to control after four days stress. Proline was accumulated up to 16.8 and 9.4 µ mol g-1FW in MCC508 and MCC521 after 4 days, which indicated an increase of 5.1 and 3.8 fold related to the control, respectively. Semi-quantification gene expression analysis for Dehydrin1and CapLEA-1 showed different response to water deficit for each genotype. Both of these genes up-regulated in tolerant genotype MCC508 with the amount of 4 and 2.1 fold compared to their respective control (p≤0.05) so that the up-regulation trend steadily continued under the stress situation. However, CapLEA-1 expression was not significantly regulated in the sensetive genotype; instead, Dehydrin1regulation was significantly evident as much as 1.4 fold increase and then decreased (p≤0.05). It, therefore, seems that stable, high up-regulation of Dehydrin1and CapLEA-1 genes and their function (stability of lipids and cell memebrane, correct protein folding and detoxificaton) might be a possible reason for high tolerancy response to water deficit in MCC508 compared to MCC521.

Identification of genetic diversity and classification of genetic resources (germplasm) are of important and essential activities in breeding and management of plant genetic resources. In order to study of genetic diversity of chickpea genotypes, 38 pair’s primers of SSR were used on 18 landrace and 30 improved varieties. After genomic DNA extraction and PCR reaction, primers produced 117 polymorphic bands and the mean of polymorphic band per primer was 3.5. The highest value of polymorphic information content (PIC) belonged to TAA170 primer (0.77) and the lowest value of PIC belonged to Cstms5 primer (0.08). Mean of PIC for all primers was 0.48. Calculated Jacard similarity coefficient ranged from 0.47 to 0.94 among genotypes. In order to assess genetic relationships, cluster analysis was performed by method NJ with Splitstree (ver 4.13.1) software. Results of this study revealed that SSR molecular markers has a valuable potential for evaluation and discrimination of chickpea genotypes.
