Description Cytoplasmic and genetic male sterility based hybrids in field crops led to tremendous
increase in productivity by exploiting the genetic principles of heterosis. Pigeonpea is
an often-cross pollinated important grain legume in rainfed cropping systems, globally
cultivated in 5 million hectares. The productivity in the crop is hovering around 800
kg/ha for the past 6 decades which is unacceptably low. The phenomenon of hybrid
vigor was successfully exploited in the crop by identifying sources of male sterility
from the wild relatives. It took three decades of research efforts to develop stable
maintainers, complete restorers and heterotic hybrid combinations. The hybrids ICPH
2671, ICPH 2740 and ICPH 3762 were released for general cultivation by the farmers
in different agroecoregions of India and a number of other hybrids are in the pipeline.
Yield advantage of 30 to 40% (rainfed) and 50 to 60% (irrigated) was realized in
farmers’ fields over the local varieties. Seed production technology was standardized
by exploiting male sterility and entomophily thereby appreciable amounts of hybrid
seeds were harvested from the seed parent. Conventional and genomic approaches are
underway to identify candidate genes responsible for fertility restoration, elite parents
with resistance to fusarium wilt and sterility mosaic disease and heterotic gene pools
to breed adaptive hybrids for different niches across the globe.
