abstract: Recently, a breeding technology for hybrid
pigeonpea [Cajanus cajan (L.) Millsp.] based
on cytoplasmic-nuclear male sterility (CMS)
and partial natural outcrossing was developed
at ICRISAT. The limited number of experimental
hybrids tested has shown the presence of a
considerable amount of hybrid vigor for seed
yield. In the present study, one extra-early- (120
d), two early- (150 d), and two late-maturing (180
d) pigeonpea hybrids were studied to generate
information on the genetics of fertility restoration
of the A4 CMS system. In the extra-earlymaturing
hybrids, pollen fertility was controlled
by a single dominant gene, whereas in the earlyand
late- maturing hybrids, male fertility was
governed by two duplicate dominant genes. It
was also observed that hybrids with two dominant
genes produced a greater pollen load and
expressed greater stability as compared with
those carrying a single dominant gene. The
information on the inheritance of fertility restoration
will help in designing strategies for breeding
elite hybrid parents, and it was concluded
that for breeding hybrids with stable fertility restoration,
the presence of two dominant genes
is essential.
