Abstract

A neglected crop of yester-years, pigeonpea (Cajanus cajan[L.] Millspaugh) is a multi-purpose, versatile food legume, which has seen greater evolution in its plant architecture, duration and yield pattern as time passed. In rainfed ecologies across the globe, pigeonpea fits in as a remunerative option to the farmers. Frequent droughts in recent past have resulted in losses to crops such as cereals, millets and oil seeds, but pigeonpea in the same cropping niche provided at least minimum assurance to small and marginal farmers, owing to its drought tolerance and ability to withstand harsh environments. The enormous variability and plasticity of the crop provided an opportunity to breeders to develop super early maturity group with the life span of less than 100 days. The existing maturity duration -- early (less than 140 days) and medium (180 to 200 days) -- imposes restrictions on adaptation to drought. The super early genotypes provide the foundation for future pigeonpea breeding because of their earliness, photo insensitive nature, impressive per day productivity, adaptability across the varying range of altitudes, stress escape mechanism and niche to fit well in various agroecologist and cropping systems. Rapid generation turnover is a boon to breeders for faster introgression of traits of interest, to carry out studies on genetics of biotic and abiotic stress by developing mapping population within very short duration. In the above context, “super early varieties and hybrids, is a wonderful breeding material to secure future sustainable dry land pigeonpea production”.
