The use of different sources of cytoplasmic
male sterility (CMS) in hybrid seed production of pearl
millet Pennisetum 9laucum (L.) R. Br.1 is advocated
to avoid possible disease epidemics occurring due to
cytoplasmic uniformity. The effects of commercially
unexploited, but potentially exploitable, sources of CMS,
like A2, A 3 and A4, on downy mildew [Sclerospora
9raminicoIa (Sacc.) Schroet] incidence were studied by
using the disease incidence of isonuclear hybrids with
male-sterile and fertile cytoplasm. The mean downy
mildew incidence of hybrids carrying different malesterile
cytoplasm was similar to that of hybrids retaining
the fertile cytoplasm. The cytoplasm accounted for only
0.6% of the total variation and its effect was non-significant;
pollinators could explain most of the variation in
determining the disease incidence of hybrids. This suggested
that these male-sterile cytoplasms are not linked
to downy mildew susceptibility and thus can be exploited
commercially to broaden the cytoplasmic base
of the male-sterile lines and, ultimately, of hybrids.
