Variability among lines of Lehmann lovegrass, Eragrostis lehmanniana Nees, was present for all plant and seed characteristics and responses studied. We reconfirmed the use of program-controlled environment to consistently evaluate large numbers of seedlings and to select genotypes which are superior for seedling drouth tolerance. There was a lack of uniform association among lines for growth habit; foliage color; anther color; chromosome number; seed dormancy, weight, size, and color; and seedling drouth tolerance. No single characteristic is adequate as a criterion of selection for seedling drouth tolerance. However, we found that lines with nondormant seed of heaviest seed weight could be discarded as drouth susceptible lines before critical evaluation and selection for seedling drouth tolerance.
