Origin and Development

Hybrid ICPH 8 was bred by hybridizing a genetic male-sterile line ms Prabhat (DT) and a male-fertile inbred line ICPL 161, both developed at ICRISAT Center. To develop the male-sterile line, the ms1 gene was transferred from the original medium-duration source genotype (MS 3A) to a short-duration pigeonpea cultivar Prabhat by backcrossing. ICPL 161 was derived through pedigree selection from the cross ICPX 74076 (ICP 6 x Pant A2) with selection number 74076-46-BI-1-HINDT4-B.
