In rice, approximately 99% of F1 hybrid cultivars have been developed using a wild abortive type of CMS (WA-CMS) and its Rf genes.
The first generation of 3-line rice hybrids was based on a wild abortive (WA) cytoplasm which was found to be a natural mutation from a wild rice (O. sativa f. spontanea) in Hainan, China (Lin and Yuan, 1980).
A wild abortive (WA -type CMS has been almost exclusively used for breeding three-line hybrid rice and contributes to 10% of the total rice cultivated area WA -typee (Li et al. [2007]; BarCMSy [2010]).
For three-line hybrid rice, wild abortive (WA) and Honglian (HL) are the representative CMS types used for commercial indica hybrid seed production, and Chinsurah Boro II (BT) is the representative CMS type used for generating japonica hybrids (Chen and Liu 2014; Huang et al. 2014; Li et al. 2007; Yuan 1994).
The same group recently used rpl5 to probe the rearranged region in the mitochondrial genome and identified the WA-CMS gene, named WA352 (Wild Abortive 352), which is comprised of three rice mitochondrial genomic segments (orf284, orf224, and orf288) and one segment of unknown origin (Figure 1), and encodes a 352-residue putative protein with three transmembrane segments (Luo et al. [2013]).
For instance, the BT-CMS (Boro II-type of CMS), WA-CMS (wild abortive-type of CMS) and HL-CMS (Honglian-type of CMS) are CMS types of rice, while the S-CMS (severely affected-type of CMS) and T-CMS (Texas-type of CMS) are of maize genotype, which arose spontaneously in a breeding line, and PET1-CMS of sunflower arose from an inter-specific cross between Helianthus petiolaris and H. annuus.
The line is distinct both genetically and cytologically from CMS-Boro (CMS-BT) rice and CMS-Wild abortive (CMS-WA) rice [ 4].
