The subgenus Allium section Allium includes economically important species such as onion (Allium cepa L.), leek (A. ampeloprasum var. porrum L.) and chives (A. schoenoprasum L.). These species have a biennial habit and many cultivars are open pollinated; and high levels of heterozygosity must be maintained.
The Allium umbel consists of a few, to hundreds of perfect flowers of per umbel.
These flowers are too small for synthetic pollination studies and due to the large-scale emasculation it is not practical so the development of hybrid cultivars is economically feasible using systems of cytoplasmic-genic male sterility (CMS). Male sterile plants, which have not got any fertile pollen, incapable of self-pollination so any seed produced must result from cross-pollination. Allium hybrid production requires the development of male-sterile, maintainer and pollinator lines with good specific combination ability.
This review outlines the using male sterility feature in hybrid breeding program for Alliums especially for onions.
