In pearl millet, cytoplasmic diversity was studied using electron microscopyatthree growth
stages of male sterile and fertile lines which represented susceptible control,Tifton 23, and
five other downy mildew resistant/immune lines. Structural superiority of the resistant
lines over susceptible control was evident, particularly for the following attributes:
polyribosomal density, granum density, mode of phenolic generation, mechanism for
cytoplasmic compartmentalisation, organization of grana and stroma in chloroplast and
shape of plasma membrane. This has been discussed as a possible criterion for selecting
lines resistant to downy mildew.
Keywords: Pearl millet, downy mildew, disease resistance, male sterile, ultrastructure.
