pigeonpea [Cajanus cajan (L.) Millsp.] based&#13;
on cytoplasmic-nuclear male sterility (CMS)&#13;
and partial natural outcrossing was developed&#13;
at ICRISAT. The limited number of experimental&#13;
hybrids tested has shown the presence of a&#13;
considerable amount of hybrid vigor for seed&#13;
yield. In the present study, one extra-early- (120&#13;
d), two early- (150 d), and two late-maturing (180&#13;
d) pigeonpea hybrids were studied to generate&#13;
information on the genetics of fertility restoration&#13;
of the A4 CMS system. In the extra-earlymaturing&#13;
hybrids, pollen fertility was controlled&#13;
by a single dominant gene, whereas in the earlyand&#13;
late- maturing hybrids, male fertility was&#13;
governed by two duplicate dominant genes. It&#13;
was also observed that hybrids with two dominant&#13;
genes produced a greater pollen load and&#13;
expressed greater stability as compared with&#13;
those carrying a single dominant gene. The&#13;
information on the inheritance of fertility restoration&#13;
will help in designing strategies for breeding&#13;
elite hybrid parents, and it was concluded&#13;
that for breeding hybrids with stable fertility restoration,&#13;
the presence of two dominant genes&#13;
is essential.</mods:abstract><mods:classification authority="lcc">Pigeonpea</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2011</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Crop Science Society of America</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
