Abstract
Abstract In tests for drought resistance in pearl millet, three methods were used: (1) growth in pots under different soil moisture tension regimes, (2) germination of seeds and growth of seedlings in mannitol solutions of different osmotic pressures, and (3) stability of extracted chlorophyll under heat treatment. The pearl millets studied represented a considerable range of ecological adaptation varying from types grown at the edge of the Rajasthan desert in India to commercially available varieties developed at Tifton, Georgia. The results showed that as the soil moisture tension increased, the growth responses for the pearl millet varieties studied decreased in the same general pattern. Differences in magnitude of responses were also observed among the varieties. It was concluded that more progress might be made by selection for early maturity in order to avoid drought than by selection for physiological drought resistance.
