Characters in the selection of winged beans (Psophocarpus tetragonolobus (L) DC) tolerant to drought


, : Characters in the selection of winged beans (Psophocarpus tetragonolobus (L) DC) tolerant to drought. Acta Horticulturae (84): 19-21

Because of its very high demand for moisture, growth of Psophocarpus tetragonolobus is restricted to the high rainfall areas of the tropics where many other legumes are known and easily cultivated; 100 different were developed at Kade to select drought-tolerant types suitable for cultivation in arid and semi-arid zones of the tropics. The types suitable to meet the dry conditions of arid zones are those having lower leaf wt. ratios, poor nodulation, thin stems and thick pulvini.
