 ABSTRACT

Pigeonpea is very sensitive to waterlogging and salinity. These two stresses adversely affect the germination and early vegetative stages of pigeonpea as compared to mature plants. Being a rainy season crop, pigeonpea is invariably exposed to intermittent waterlogging conditions for different durations from germination to early vegetative growth stages. The objective of this study was to screen thirty pigeonpea [Cajanus cajan (L.) Millsp.]  genotypes HO6-1, HO6-12, HO3-41, HO9-27, HO9-33, HO9-34, HO9-36, HO9-38, MANAK, PARAS, ICPH 2431, ICPH 2671, ASHA, MARUTI, ICPL 87051, ICP 5028, ICPL 20096, ICPL 87091, ICPL 20241, LRG 30, ICPL 20120, MAL 9, ICPL 20238, ICPL 20237, MAL 12, SIPS 2, SGBS 6, ICP 8857, UPAS 120 and ICP 7035 for waterlogging, salinity (60mM NaCl) and combined waterlogging plus salinity (30mM NaCl) tolerance. These treatments were resulted in visible yellowing and senescence of leaves, decreased plant survival, chlorophyll content and chlorophyll fluorescence. The genotypes ICPH 2431, PARAS, HO9-33, HO6-1, HO6-12, HO9-36 were found relatively tolerant while UPAS 120, SGBS 6, MAL-12, ICPL 20237, HO9-34, LRG 30 were relatively sensitive to waterlogging and salinity treatments.

Key words: Pigeonpea, Waterlogging, Salinity, Saline Waterlogging, Plant Survival, Chlorophyll Fluorescence.
