Assessment of agro-morphological and molecular diversity among fertility restorer lines in wheat (Triticum aestivum L.)

Published on

Genetic diversity among eight diverse fertility restorer
lines of exotic and indigenous origin was studied using
agronomic characters and molecular markers. Thirty eight
of the 79 SSR markers used were found polymorphic
yielding a total of 113 alleles with mean polymorphism
information content (PIC) of 0.37 per marker. Dendrograms
resulting from an UPGMA cluster analysis classified the
fertility restorer lines into two main clusters with distinct
sub-grouping. On the whole a very low range of genetic
similarity (GS) was observed, which indicated that the
fertility restorer lines used in the study are genetically
diverse. There was low correspondence between the
similarity matrices as obtained with morphological and
molecular data. The information deduced from the study
can be utilized in hybrid breeding programme as well as
in producing combination of different fertility restorer
genes in a single genetic background.
