Allium cepa hybrids cytoplasmic genetic male sterility molecular marker restorer lines
Onion (Allium cepa) is an important vegetable/spice crop worldwide. It is an open pollinated crop; therefore, development
of onion hybrids is most sought out option to boost onion productivity. Use of cytoplasmic genetic male sterility (CGMS)
is most pragmatic method ofonion hybrid development. This includes use of three lines, i.e., cytoplasmic male sterile line
(A), its isogenic fertile maintainer line (B) and fertility restorer line (R). The conventional method of hybrid development
is less efficient as compared to molecular marker assisted methods for identification of S, T, N cytoplasm, maintainer lines
and fertility restorer genes with high heterosis. Various molecular marker systems have been established for commercial
hybrid seed production. This review examines the development and identification of male sterile and its maintainer lines
as well as restorer lines for hybrid seed production using conventional and molecular marker assisted methods.
