In order to identify drought tolerant chickpea genotypes, an experiment was conducted in the west of Iran, during 2007-2009 cropping seasons. Several selection indices were used to illustrate genotypic differences in response to drought stress. The results of combined analysis of variance showed that year, genotype, stress conditions and their interaction effects were highly significant. Correl...

Production of grain legumes is severely reduced in salt-affected soils because their ability to form and maintain nitrogen-fixing nodules is impaired by both salinity and sodicity (alkalinity). Genotypes of chickpea, Cicer arietinum, with high nodulation capacity under stress were identified by field screening in a sodic soil in India and subsequently evaluated quantitatively for nitrogen fixat...

The results of studies on in vitro regeneration of chickpea (Cicer arietinum L.) have shown that indirect regeneration via callus was not successful. The introduction of an efficient and repeatable regeneration protocol is necessary for using transgenic technologies for the improvement of chickpea. The present study was undertaken to investigate the possibility of indirect regeneration in vario...

Ascochyta blight caused by Ascochyta rabiei (Pass.) Labrousse is a major biotic constraint in production of chickpea. In the present investigation, all chickpea genotypes [E100Y (m), Gaurav, Pb-7 and L550] induced 100% callus on standard medium with greenish colour and fragile structure. These calli were used for in vitro screening against pathogen, A. rabiei culture filtrate at 0, 5, 10, 15 an...

Experiments were conducted to study the nodular metabolism, in order to draw comparisons between nitrogen fixation, carbon fixation and ammonia assimilation in nodule cytosol of desi (CSG 8962, DCP 92-3) and kabuli (CSG 9651, BG 267) genotypes of chickpea. Maximum acetylene reduction activity (ARA) was observed in CSG 9651 and minimum in DCP 92-3.The specific activity of ammonia assimilating en...

A set of 2486 single nucleotide polymorphisms (SNPs) were compiled in chickpea using four approaches, namely (i) Solexa/Illumina sequencing (1409), (ii) amplicon sequencing of tentative orthologous genes (TOGs) (604), (iii) mining of expressed sequence tags (ESTs) (286) and (iv) sequencing of candidate genes (187). Conversion of these SNPs to the cost-effective and flexible throughput Competiti...

Pakistan is among top three chickpea producing countries but the crop is usually grown on marginal lands without irrigation and fertilizer application which significantly hampers its yield. Soil fertility and inoculation with beneficial rhizobacteria play a key role in nodulation and yield of legumes. Four kabuli and six desi chickpea genotypes were, therefore, evaluated for inoculation respons...

Ascochyta blight is one of the major diseases of chickpea worldwide. The genetic resistance to ascochyta blight in chickpea is complex and governed by multiple QTLs. However, the molecular mechanism of quantitative disease resistance to ascochyta blight and the genes underlying these QTLs are still unknown. Most often disease resistance is determined by resistance (R) genes. The most predominan...

knowledge of the relation between agronomical traits with economical yield is very important in crop improvement and breeding. in order to study of genetic diversity and identifying yield components, 568 kabuli type germplasm and 390 desi type chickpea germplasm that were available in pulses collection of faculty of agriculture, university of tehran, was investigated in this research in 2009 in...

Double haploid technique is not routinely used in legume breeding programs, though recent publications report haploid plants via anther culture in chickpea (Cicer arietinum L.). The focus of this study was to develop an efficient and reproducible protocol for the production of double haploids with the application of multiple stress pre-treatments such as centrifugation and osmotic shock for gen...
