Author(s):

Abstract:
Ten host differentials of Pigeonpea (Cajanus cajan L. Millsp) viz., Bahar, BRG 1, BDN 1, ICP 7035, IPA 8F, BSMR 736, BRG 2, Purple 1, ICP 2376 and ICP 8863 were studied for symptomatology of pigeonpea sterility mosaic disease by using infector row and leaf stapling technique. Disease incidence and incubation period was recorded. Reduction in leaf size, stunted plant growth, severe mosaic symptoms and complete sterility was observed in BDN 1 and ICP 8863 host differentials whereas mild chlorosis was observed on BRG 1 and ICP 7035 host differentials. Mild mosaic without sterility was recorded on IPA 8F whereas no apparent symptom of pigeonpea sterility mosaic disease was observed on Bahar. Mild vein clearing, mild to severe mosaic with ring spots was observed on ICP 2376 host differential while light and dark green mosaic pattern, pale green appearance, severe mosaic and finally reduction of plant growth was recorded on BRG 2. Mild to severe mosaic symptoms, cessations of flowers, dark green mosaic pattern and reduction of plant growth on Purple-1 host differential whereas mild to severe mosaic symptoms, cessations of flowers, reduction in leaf size and stunted plant growth on BSMR 736 was recorded.
Genotypes found resistant to moderately resistant can be utilized as parents for transferring stable sterility mosaic resistance in varietal breeding programme.
