In another study using the same reference population, an advanced linkage map spanning 1497.7 cM with 406 loci including 177 gene-based markers and 126 genomic SSRs (gSSRs) has been developed ( Choudhary et al., 2012 ). More information: Thomas Stefaniak et al, Comparison of Hybridization Techniques in Chickpea, Crop Science (2016). In-ovulo embryo culture is favored rather than directly culturing the hybrid embryos on the medium. Tissue culture techniques play an important role in the utilization of wild Cicer species for the improvement­ of cultivated chickpea. These techniques were more informative than previously used biochemical and molecular methods to study variation and genetic relationships in chickpea such as isozymes, storage proteins (Ahmad and Slinkard 1992; Labdi et al. BACKGROUND: Two crossing techniques for hybridization of chickpea have been reported and include pollination after emasculation and pollination without emasculation. DOI: 10.2135/cropsci2016.04.0253 Provided by American Society of Agronomy Success of crossing with emasculation varied from 5 to 17%; while the success rate varied from 20 to 50% by pollination without emasculation. 24. The effort focuses primarily on enhanced germplasm developed by crossing chickpea's wild relatives with elite cultivars, greatly increasing genetic and trait diversity. Utilization of wild Cicer species has become essential as a series of evolutionary bottlenecks have narrowed the genetic base of chickpea, thus making it susceptible to a range of diseases and pests. Besides conventional techniques, bold approaches must also be taken towards the breeding of a crop for achieving significant yield advances.

In wild chickpea (C. reticulatum), a considerable proportion of the mature pods remain intact, and this characteristic leads to the species being described as pre-adapted to domestication. Chickpea is an important legume crop, providing a protein rich diet for humans and animal feed. With the development of embryo rescue and tissue culture techniques for chickpea wide crosses at ICRISAT, it was possible to cross C. arietinum with C. bijugum and obtain healthy hybrids. Tissue culture techniques play an important role in the utilization of wild Cicer species for the improvement- of cultivated chickpea. Therefore, a new approach is needed to utilise the more distantly related species in the secondary and tertiary genepools. The importance of crossing between the two major subgroups (desi and kabuli) of chickpea has been well established since long.
