The experiment on effect of foliar spray of nutrients, growth regulators on seed yield and genetic purity testing in hybrid pegionpea [Cajanus cajan (L.) Millsp] was conducted at Seed Farm, College of Agriculture, Vijayapura, during Kharif 2019-2020. The treatment viz., foliar spray of control (T1), 1% Pulse magic (T2), 1% 19:19:19 (T3), 0.2% Borax (T4), 50 ppm NAA (T5), 1% Pulse magic+1%19:19:19 (T6), 1% Pulse magic+0.2% Borax (T7), 1% Pulse magic+50 ppm NAA (T8), 1% Pulse magic+1% 19:19:19+0.2% Borax (T9), 1% Pulse magic+ 1% 19:19:19+50 ppm NAA (T10), 1% Pulse magic+1% 19:19:19+50 ppm NAA+0.2% Borax .Foliar spray was taken at flowering stage pod filling stage. The results revealed that, foliar application of Pulse magic@1%+19:19:19@1%+ NAA@50 ppm + Borax@0.2% revealed that, the higher seed quality parameters viz: seedling vigour index I and II observed 2649 and 407, higher germination (92.67 %) respectively. The CCtc006 amplified an allele of size 230 bp in seed parent (ICPA 2039) but not its pollen parent (ICPR 2438). Further, the CCtc006 also amplified allele of size 220 bp in pollen parent (ICPR-2438) which restores the fertility in male sterile parent. Therefore, the presence of both the amplicon at 220 and 230 bp were noticed in F1 hybrid, thus conforming hybridity of pigeonpea hybrid ICPH 2438.
