The TCGC Consortium aims to increase chickpea production and productivity by utilizing modern genomics approaches in breeding and popularizing improved varieties. Through marker-assisted backcrossing, lines with enhanced drought tolerance and fusarium wilt resistance were developed in the genetic background of elite chickpea varieties. Multi-location evaluations identified top performing desi and kabuli lines, while Farmer Participatory Varietal Selection trials helped promote 16 improved varieties in villages across five states. The efforts of TCGC have led to the development and adoption of high-yielding varieties that will benefit chickpea farmers.
The Translational Chickpea Genomics Consortium (TCGC) was set up to increase the production and productivity of chickpea (Cicer arietinum L.). It represents research institutes from six major chickpea growing states (Madhya Pradesh, Maharashtra, Andhra Pradesh, Telangana, Karnataka and Uttar Pradesh) of India. The TCGC team has been engaged in deploying modern genomics approaches in breeding and popularizing improved varieties in farmers' fields across the states. Using marker-assisted backcrossing, introgression lines with enhanced drought tolerance and fusarium wilt resistance have been developed in the genetic background of 10 elite varieties of chickpea. Multi-location evaluation of 100 improved lines (70 desi and 30 kabuli) during 2016-2017 and 2018-2019 enabled the identification of top performing desi and kabuli lines. In total, 909 Farmer Participatory Varietal Selection trials were conducted in 158 villages in 16 districts of the five states, during 2017-2018, 2018-2019, and 2019-2020, involving 16 improved varieties. New molecular breeding lines developed in different genetic backgrounds are potential candidates for national trials under the ICAR-All India Coordinated Research Project on Chickpea. The comprehensive efforts of TCGC resulted in the development and adoption of high-yielding varieties that will increase chickpea productivity and the profitability of chickpea growing farmers.
