Description Pigeonpea [Cajanus cajan (L.) Millsp.] is an important pulse crop of Indian rainfed agriculture. Of the
3.47 m ha grown under the crop in India with mean productivity of 711 kg/ha, the central and southern India
contributes over 72.8% in area and 69.5% in production with a mean yield of 649.2 kg/ha.(DAC, 2011). In
spite of dedicated variety breeding efforts, the productivity of pigeonpea has remained unacceptably low
for over 50 years. Photoperiod and thermoperiod sensitivity and perenniabiltiy are the major issues that
cause hindrance in quality seed production of the crop. To break this yield plateau, a hybrid breeding
technology, based on natural out-crossing and cytoplasmic nuclear and genetic male-sterility (CGMS)
systems were developed at ICRISAT and PJTSAU and a number of hybrids with 30-100% yield advantages
overthe control were identified. Amongthese, ICPH 2740 wasfound most outstanding. In 31 multi-location
trials conducted over five years, this hybrid (2793 kg/ha) recorded 41% superiority over the ruling variety
Asha (1985 kg/ha). The performance record of hybrids suggests that this technology has a potential for
breaking yield barrier in pigeonpea. Genome sequencing (Varshney et al. 2012), development of photo
insensitive super early maturing lines, introgression of cleistogamous flower structure to maintain genetic
purity of elite lines, use of obcordate leaf shape as NEP to assess genetic purity of hybrid parental lines and
development of disease resistant hybrids and elite breeding lines are some of the recent innovations in the
crop which offer a scope for the enhancement of production and productivity and ushers the crop as an
economical viable option by the public and private seed industry.
