Description Pigeonpea is one of the important pulse crops grown in many states of India and plays
a major role in sustainable food and nutritional security for the smallholder farmers. In order to
overcome the productivity barrier the Translational Pigeonpea Genomics Consortium (TPGC) was
established, representing research institutes from six different states (Andhra Pradesh, Karnataka,
Madhya Pradesh, Maharashtra, Telangana, and Uttar Pradesh) of India. To enhance pigeonpea
productivity and production the team has been engaged in deploying modern genomics approaches
in breeding and popularizing modern varieties in farmers’ fields. For instance, new genetic stock
has been developed for trait mapping and molecular breeding initiated for enhancing resistance to
fusarium wilt and sterility mosaic disease in 11 mega varieties of pigeonpea. In parallel, genomic
segments associated with cleistogamous flower, shriveled seed, pods per plant, seeds per pod,
100 seed weight, and seed protein content have been identified. Furthermore, 100 improved lines
were evaluated for yield and desirable traits in multi-location trials in different states. Furthermore,
a total of 303 farmers’ participatory varietal selection (FPVS) trials have been conducted in 129 villages
from 15 districts of six states with 16 released varieties/hybrids. Additionally, one line (GRG 152
or Bheema) from multi-location trials has been identified by the All India Coordinated Research
Project on Pigeonpea (AICRP-Pigeonpea) and released for cultivation by the Central Variety Release
Committee (CVRC). In summary, the collaborative efforts of several research groups through TPGC is
accelerating genetics gains in breeding plots and is expected to deliver them to pigeonpea farmers to
enhance their income and improve livelihood.
