“…In the present study, the pollen non-formation type CMS line could be developed. Expression of male-sterility in the CMS line developed by Saito et al (2009) is similar to the present study; however, a single Rf gene is assumed to control fertility restoration in their line. The difference in the number of Rf genes implies a difference between the mechanisms of these two CMS systems.…”

“…Genic male-sterility derived from spontaneous mutation has been reported (Chauhan, 1984;Jasmin, 1954;Nuttall, 1963;Phatak and Jaworski, 1989;Phatak et al, 1991). Cytoplasmic male-sterility derived from inter-specific crosses, in which wild Solanum species was used as the female parent followed by repeated backcrossing to the cultivated species to achieve cytoplasm substitution, have been reported (Fang et al, 1985;Isshiki and Kawajiri, 2002;Isshiki, 2008, 2009;Saito et al, 2009 term commercially viable hybrid breeding programs, the use of a limited number of male-sterility sources usually implies a potential risk as a result of the vulnerability of a narrow genetic basis. For example, intensive use of a single source of male-sterile cytoplasm in developing hybrid cultivars was found to be disastrous in the case of Texas cytoplasm in maize (Hooker, 1974); therefore, diverse sources of male-sterility are essential to widen this genetic base and to reduce the genetic vulnerability of cultivated eggplant.…”

In order to develop a new male-sterile line of eggplant (Solanum melongena L.), the F 1 rootstock 'Assist' (Solanum aethiopicum Aculeatum L. Group × S. melongena 'DMP') was continuously backcrossed to S. melongena 'Uttara' using 'Uttara' as a recurrent pollen parent up to BC 4 generation. All examined F 1 'Assist' produced pollen grains while BC 1 plants segregated into male fertile and sterile plants. The male-sterile plant did not produce any pollen grains. BC 2 , BC 3 , and BC 4 progenies obtained from male fertile backcross progenies were segregated into male fertile and sterile plants and each segregation ratio fitted 3 : 1. BC 3 and BC 4 progenies obtained from male-sterile backcross progenies were fixed to male-sterility without segregation. Selfed progenies of the male fertile BC 2 progeny were segregated into male fertile and sterile plants and the segregation ratio fitted 15 : 1. Therefore, the pollen non-formation characteristic is assumed to be a form of cytoplasmic male-sterility (CMS), induced by incompatibility between the cytoplasm of S. aethiopicum Aculeatum Group and the nucleus of S. melongena. Further, these segregation results indicated that two independent dominant fertility restorer (Rf) genes control the fertility restoration of this CMS. High values of fruit set, number of seeds per fruit, and the seed germination rate found in BC 4 progenies indicate that the cytoplasm of S. aethiopicum Aculeatum Group has no notable negative effect on seed fertility of S. melongena. A new male-sterile line of eggplant could be developed by utilizing the cytoplasm of S. aethiopicum Aculeatum Group.

Cytoplasmic male sterility (CMS) is a useful system to produce hybrid seeds in a variety of crop species. In eggplant, CMS systems were developed utilizing the cytoplasms of six wild Solanum species by repeated backcrossings. These CMS systems were classified into two types. The first one is anther indehiscent-type sterility in the CMS systems of eggplant with the cytoplasms of Solanum kurzii Brace & Prain, S. violaceum Ort., and S. virginianum L., in which anther contains normal pollen but does not open to release. The second one is pollen non-formation-type sterility in the CMS systems of eggplant with the cytoplasms of S. aethiopicum Aculeatum Group, S. anguivi Lam., and S. grandifolium C.V. Morton, in which anther of the male-sterile lines is completely devoid of pollen. Both types of sterility system were characterized by investigating pollen and seed fertility. Furthermore, in pollen non-formation CMS systems, two independent dominant fertility restorer (Rf) genes were discovered and a sequenced characterized amplified region (SCAR) marker tightly linked to these genes was developed.
