“…The segregation ratio of the number of non‐segregating male‐fertile F 2:3 families : number of 3 : 1 segregation F 2:3 families : number of 15 : 1 segregation F 2:3 families fitted a 7 : 4 : 4 ratio by chi‐square test ( χ 2 = 0.257, P = 0.879) as expected. All the above phenotypic and genotypic segregation data demonstrated the hypothesis that male fertility restoration of NJCMS1A was controlled by two pairs of duplicate dominant genes, which further verified the results of Bai and Gai (2005).…”

“…1998). Bai and Gai (2005) revealed that two duplicate dominant genes controlled the male fertility restoration of NJCMS1A. The genotype of NJCMS1A and NJCMS1B was designated as S( rf 1 rf 1 rf 2 rf 2 ) and N( rf 1 rf 1 rf 2 rf 2 ), respectively, while those of the restorers found in their study were grouped into four categories: (i) the cytoplasmic genotype was unknown and the nuclear genotype was two pairs of duplicate dominant genes, i.e.…”

“…Segregation analysis: The male‐fertile and male‐sterile plants in each family of F 1:2 and F 2:3 were counted, respectively, at the flowering stage and then checked at maturity according to Bai and Gai (2005). Chi‐square tests were used to test the segregation ratio of male‐fertile to male‐sterile plants in each family of each generation, as well as its homogeneity among the families.…”

The F 1 , F 2 and F 2:3 of the NJCMS1A · ÔZhongdou 5Õ cross were used to analyse the inheritance of the male fertility restoration of the cytoplasmic-nuclear male-sterile line NJCMS1A in soybean. The results of genetic analysis showed two pairs of dominant genes conferring the male fertility restoration of NJCMS1A, which further confirmed previous results. The F 2 population from the NJCMS1A · ÔZhongdou 5Õ cross was used for tagging the restorer genes for NJCMS1A with 664 pairs of simple sequence repeat primers selected randomly from the genetic linkage map of soybean published by Cregan et al. (1999). Satt626 on linkage group M and Satt300 on linkage group A1 of the integrated linkage map by Song et al. (2004) were found to link to the two restorer genes of NJCMS1A. The maximum-likelihood estimates of the genetic distance between the two markers, Satt626 and Satt300, and the two restorer genes of ÔZhongdou 5Õ were 9.75 and 11.18 cM, respectively.Key words: Glycine max -cytoplasmic-nuclear male sterilitymale fertility restoration -simple sequence repeat marker Utilization of heterosis is an effective way to increase crop yields. Cytoplasmic-nuclear male sterility plays an important role in the production of hybrid seeds. Davis (1985) reported soybean cytoplasmic-nuclear male sterility in a patent as the earliest one, but no further work was announced. 3 reported their own results on the development of cytoplasmic-nuclear male-sterile lines along with corresponding maintainers and restorers. The knowledge of inheritance of male fertility restoration of a cytoplasmic-nuclear male-sterile line is essential to hybrid seed production. With the rapid development of molecular markers, mapping male fertility restoration genes appears an effective way to study inheritance of the trait. So far, there are very few papers on tagging the restorer genes with molecular markers in soybeans, except for Xu et al. (1999) who reported that three simple sequence repeat (SSR) markers, Satt143, Satt168 and Satt441, might relate to male fertility restoration of soybean cytoplasmic-nuclear malesterile lines FuCMS1A and FuCMS2A, but without any statement regarding the genetic distance between these SSR markers and the restorer genes.The soybean cytoplasmic-nuclear male-sterile line NJCMS1A was developed through consecutive backcross procedures with the cultivar ÔN8855Õ as donor parent and N2899 (designated as NJCMS1B afterwards) as recurrent parent (Gai et al. 1995, Ding et al. 1998. Bai and Gai (2005) revealed that two duplicate dominant genes controlled the male fertility restoration of NJCMS1A. The genotype of NJCMS1A and NJCMS1B was designated as S(rf 1 rf 1 rf 2 rf 2 ) and N(rf 1 rf 1 rf 2 rf 2 ), respectively, while those of the restorers found in their study were grouped into four categories: (i) the cytoplasmic genotype was unknown and the nuclear genotype was two pairs of duplicate dominant genes, i.e. N/S(Rf 1 Rf 1 Rf 2 Rf 2 ); (ii) the cytoplasmic genotype was malesterile and the nuclear genotype was two pairs of duplicate domi...

“…Consequently, there also might exist different genetic mechanism between NJCMS3A and NJCMS1A. The previous studies (Bai and Gai 2005) showed two pairs of duplicated sporophyte male-sterile genes controlling the male sterility and male-fertility restoration of NJCMS1A, while the male sterility of NJCMS3A might be conditioned with a pair of gametophyte male-sterile genes according to the present study. Another interesting thing is that both NJCMS1B (N2899) and NJCMS3B (N21249) could maintain the male sterility of NJCMS1A and NJCMS3A.…”

Most of the cytoplasmic-nuclear malesterile (CMS) lines of soybean were developed only from a limited cytoplasm sources and performed not as good as required in hybrid seed production, therefore, to explore new male-sterile cytoplasm sources should be one of the effective ways to improve the pollination and hybridization for a better pod-set in utilization of heterosis of soybeans. In the present study, total 80 crosses between 70 cultivated and annual wild soybean accessions and three maintainers (N2899, N21249, and N23998) of NJCMS1A were made for detecting potential new sources with male-sterile cytoplasm. The results showed that in addition to the crosses with N8855.1 (the cytoplasm donor parent of NJCMS1A) and its derived line NG99-893 as cytoplasm parent, there appeared three 2006 fertility segregation of crosses between NJCMS3A and three restorers. The nuclear gene(s) of male sterility in NJCMS3A appeared different from the previously reported CMS lines, NJCMS1A and NJCMS2A. The development of NJCMS3A demonstrated the feasibility to discover new CMS system through choosing maintainers with suitable nuclear background.

“…A large body of the researchers rather conducted experiments on CMS rf ‐genes than on CMS‐related genes in soybean. Bai and Gai () suggested that two pairs of duplicate dominant genes regulated the male fertility restoration of NJCMS1A; same results were witnessed by Yang et al (). Two independent rf ‐genes loci, Satt626 on linkage group (LG) “M” and Satt300 on LG “A1”, were identified that is assumed to be related to male fertility restoration of NJCMS1A (Yang et al, ).…”

In plants, male sterility (MS) is a specific breeding target trait. With the advancements in agriculture, utilization of heterosis breeding in hybrid production through MS lines has become the main breeding tool of various cross‐pollinated and even self‐pollinated crops. Soybean is an essential source of oil and protein; however, the low yield is a major factor limiting its development. Soybean MS mainly comprises cytoplasmic‐nuclear MS and nuclear/genic MS (NMS/GMS), which can effectively utilize heterosis to improve soybean yield. This review outlines the recent research progress on the development of new genetically MS lines, exploring the underlying molecular mechanism of MS, identification and cloning of MS and fertility restoration genes, and the application of MS lines. We further discussed and prospected the future developmental scenario direction of the soybean MS, based on the previous studies of other crops sterility system. Moreover, this review also provides comprehensive information for better application of MS to soybean breeding programme.
