A collaborative effort was undertaken between the Crop Development Centre (Saskatoon, Canada), CLIMA (Crawley, Australia) and ICRISAT (Patancheru, INDIA) to develop an improved interspecific hybridization protocol in order to widen the genetic base of the cultivated chickpea... Keeping the hybrid embyos/ovules on the parent plant as long as possible increases the likelihood that hybrids develop to the globular or heart 4 thInternational Food Legume Research Conference October 18-22, 2005, New Delhi, India shaped stage... An experiment was conducted comparing a one-time hormone application to a daily application until the time of rescue...

The hypothesis for our studies is that optical and transmission electron microscopy (TEM) studies of embryogenesis in interspecific hybrids will aid in the identification of such barriers... For hybridisation, buds of chickpea were emasculated before anthesis, and the stigma was hand pollinated with fresh pollen from C. bijugum to create the interspecific hybrids... In summary, optical microscopy studies of embryogenesis, in both selfs and hybrids, identified deleterious changes in the fertilised hybrid seed as early as 2 to 4 days after pollination in some crosses...

Embryo rescue and plant regeneration in vitro of selfed chickpea (Cicer arietinum L.) and it's wild annual relatives.. The aims of this study were to examine embryogenesis in selfed and hybridised ovules; to develop robust techniques to rescue immature embryos in_vitro using selfed chickpea ovules; to regenerate plantlets from rescued chickpea ovules; and to apply the best techniques to rescue interspecific hybrids... Some cross pollinated ovules were rescued in_vitro and putative hybrid plantlets were regenerated...
