Description Pigeonpea is a hardy, widely adapted, drought tolerant crop and
an integral component of cropping systems of small and marginal
farmers of SAT regions of the globe. The global pigeonpea
area, production and yield is approximately 6.23 mha, 4.74 MT
and 762.4 kg ha -1 respectively (FAOSTAT 2015). Inflated market
prices coupled with stagnant productivity have created a
substantial demand supply gap. This alerted breeders to break
the yield plateau by harnessing the inherent heterotic potential,
as no further horizontal increase in area under pigeonpea was
possible. Yield advantage in maize, rice, wheat and grain sorghum
through hybrid technology triggered the adaptance of the
latter in pigeonpea. As hand emasculation and pollination was
not commercially feasible, male sterile lines became imperative
for utilization of available natural out-crossing in pigeonpea.
Thus, the first pigeonpea hybrid ICPH 8 was developed using
GMS source in 1991, followed by PPH4, CoH1, AKPH4104 and
AKPH2022.Though the bottlenecks of GMS system led to the
development of the first CMS- based pigeonpea hybrid GTH-1
the first commercial CMS hybrid was ICPH 267. It has greater
root mass, depth and ability to draw moisture from deeper soil
profiles. Its fast root growth also helps in overcoming short spells
of early season drought that is often encountered in July-sown
rainfed crops. Hybrids have recorded 20% to 30% yield advantage
over existing varieties and seed production technology has
been standardized for large-scale production of commercial hybrids.
SSR based hybrid purity assessment kits are also developed
for testing GOT. The hydraulic characteristics of pigeonpea
roots is an interesting asset for both nutrient and water uptake.
In this context, hybrid pigeonpea is the best bet for maximizing
dryland productivity.
