Fertility restoration in cytoplasmic genic male sterile line of pigeonpea [Cajanus cajan (L.) Millsp.] derived from Cajanus scarabaeoides

Published on

For commercial exploitation of heterosis, efficient and
stable cytoplasmic genic male sterility system is developed
using first CGMS line GT-288A1B alongwith fertility
restoration mechanism from interspecific hybridization. To
identify perfect pollen fertility restorers, 543 derivative
lines of F
s and F6 populations of Cajanus scarabaeoides
x Cajanus cajan and 1365 germplasm accessions were
used as pollen parent on stable cytoplasmic genic male
sterile line GT-288A during kharif 1997 to 2003. The F1
progenies of all the crosses were evaluated during kharif
1998 to 2003 for their pollen fertility. The promising pollen
fertility restoring parents were advanced and purified
through selection and selfing. Finally eighteen -fertility
restorers were identified and characterized.
