Chickpea Hybridization Using In Vitro Techniques [PDF]

open access: yes, 2010
Tissue culture techniques play an important role in the utilization of wild Cicer species for the improvement- of cultivated chickpea. 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.
