“…For example, in chickpea, in addition to the well-known drought tolerant accession, ICC 4958, new sources of drought tolerance have been identified using different techniques (Table 4); ICC 13124 has the highest drought tolerance efficiency (DTE), lowest drought susceptibility index (DSI) and the highest harvest index (HI) and has been identified as the most drought tolerant accession (Parameshwarappa and Salimath, 2008; Parameshwarappa et al, 2010). Recently, to combat the effect of climate change on grain legume production, new and diverse sources of heat tolerance (Krishnamurthy et al, 2011a; Upadhyaya et al, 2011a), herbicide tolerance (Tar'an et al, 2010) and accessions with greater biological nitrogen fixation (BNF) capacity (Biabani et al, 2011) for chickpea and water-logging tolerant accessions for pigeonpea improvement (Krishnamurthy et al, 2011b) (Table 4) have also been identified.…”

The narrow genetic base of cultivars coupled with low utilization of genetic resources are the major factors limiting grain legume production and productivity globally. Exploitation of new and diverse sources of variation is needed for the genetic enhancement of grain legumes. Wild relatives with enhanced levels of resistance/tolerance to multiple stresses provide important sources of genetic diversity for crop improvement. However, their exploitation for cultivar improvement is limited by cross-incompatibility barriers and linkage drags. Pre-breeding provides a unique opportunity, through the introgression of desirable genes from wild germplasm into genetic backgrounds readily used by the breeders with minimum linkage drag, to overcome this. Pre-breeding activities using promising landraces, wild relatives, and popular cultivars have been initiated at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) to develop new gene pools in chickpea, pigeonpea, and groundnut with a high frequency of useful genes, wider adaptability, and a broad genetic base. The availability of molecular markers will greatly assist in reducing linkage drags and increasing the efficiency of introgression in pre-breeding programs.

“…It should be noted that, unlike the nitrogenase activity expressed per plant per hour, the specific nitrogenase activity (per gram dry weight nodule per hour) did not appear to correlate well with nodule number and weight (Rupela, 1990). Likewise, N-fixation rates in chickpea assessed by the percentage of total N and the 15 N/ 14 N isotope ratio method correlated very weakly with nodule number and weight (Biabani et al, 2011). Biabani et al (2011) also emphasized that nodule number taken alone is a poor estimator of SNF effectiveness in chickpea and advocated the simultaneous use of several independent characteristics.…”

“…Individual nodules reach 3-4 mm in length (Aouani et al, 2001). The number of nodules per plant may lie within the following ranges, depending on chickpea genotype, rhizobial strain, and growth conditions: 2-14 (Gul et al, 2014), 8-38 (Khurana and Dudeja, 1996), 13-30 (Ben Romdhane et al, 2007), 20-36 (Aouani et al, 2001, or 21-101 (Biabani et al, 2011). Nodule dry weight per plant varies between 60 and 500 mg (Aouani et al, 2001).…”

Zn deficiency is widespread in traditional areas of chickpea cultivation worldwide. It limits chickpea productivity and causes significant losses to the economies of the world's largest chickpea exporters. This review may be of interest to researchers who would like to contribute to the improvement of chickpea cultivation on Zn-depleted soils in an environmentally sustainable manner, namely via identification of genotypes with superior symbiotic performance under Zn-limited conditions. The primary aim of the current work is to familiarize the readers with the biology and symbiotic characteristics of chickpea, and also to provide the necessary background on Zn as an essential nutrient for symbiotic nitrogen fixation (SNF). Special attention has been paid to the choice of rhizobial strains compatible with chickpea. Strains that can serve as an inoculum for simultaneous analysis of many genetically diverse chickpea lines have been suggested. The genotypes listed in this work can be good starting material for identification of chickpea lineages useful for unraveling the molecular basis of Zn-use efficiency, SNF efficiency, or both.

“…Nevertheless, while there are various benefits of improved N fixation, attempts at targeted breeding have been minimal (Herridge and Rose, 2000). Genetic diversity for traits related to enhanced N fixation has been identified in soybean (Nicolas et al, 2002;Hungria and Bohrer, 2000), field pea (Buttery et al, 1992), model species Medicago truncatula (Rangin et al, 2008), common bean (Redden and Herridge, 1999;Rodino et al, 2005), chickpea (Biabani et al, 2011), and others.…”
