“…Then, simple sequence repeat (SSR) markers linked to genetic male sterility genes can play important roles in early identification and removal of male-fertile plants before flowering (Horner and Palmer 1995). In addition, these kinds of molecular markers also can be used for male-sterile line selection in backcrossing and recurrent selection breeding programs (Lewers and Palmer 1997). It is possible to facilitate identification of morphological markers linked to the genes for development of genetic linkage maps for male sterility genes, which can be utilized for quick and easier selection of male-sterile lines (Ott et al 2013).…”

In soybean, an environmentally stable male sterility system is vital for making hybrid seed production commercially viable. Eleven male-sterile, female-fertile mutants (ms1, ms2, ms3, ms4, ms5, ms6, ms7, ms8, ms9, msMOS, and msp) have been identified in soybean. Of these, eight (ms2, ms3, ms5, ms7, ms8, ms9, msMOS, and msp) have been mapped to soybean chromosomes. The objectives of this study were to (i) locate the ms1, ms4, and ms6 genes to soybean chromosomes; (ii) generate genetic linkage maps of the regions containing these genes; and (iii) develop a comprehensive map of all known male-sterile, female-fertile genes in soybean. The bulked segregant analysis technique was used to locate genes to soybean chromosomes. Microsatellite markers from the corresponding chromosomes were used on F2 populations to generate genetic linkage maps. The ms1 and ms6 genes were located on chromosome 13 (molecular linkage group F) and ms4 was present on chromosome 2 (molecular linkage group D1b). Molecular analyses revealed markers Satt516, BARCSOYSSR_02_1539, and AW186493 were located closest to ms1, ms4, and ms6, respectively. The ms1 and ms6 genes, although present on the same chromosome, were independently assorting with a genetic distance of 73.7 cM. Using information from this study and compiled information from previously published male sterility genes in soybean, a comprehensive genetic linkage map was generated. Eleven male sterility genes were present on seven soybean chromosomes. Four genes were present in two regions on chromosome 2 (molecular linkage group D1b) and two genes were present on chromosome 13 (molecular linkage group F).

“…However, a genetic component probably exists as shown by insect-mediated cross-pollination with phenotypic recurrent selection (Ortiz-Perez et al 2008). Recurrent selection in soybean with male-sterile, female-fertile mutants was reviewed by Lewers and Palmer (1997). These genetic differences in soybean should be amenable to plant breeding manipulation similar to what has been with alfalfa (Teuber et al 1983(Teuber et al , 1990.…”

The field of plant breeding covers a broad range of different species and categories of plants. While there are many techniques and issues that are similar across these species, many more are unique to each genus.The Handbook of Plant Breeding is organized by major crop categories and includes the most up-to-date molecular techniques being used. It will serve as a resource for plant breeding laboratories in both the university and industrial setting.More information about this series at

“…To date, male‐sterile, female‐fertile soybean lines have been used in research for population development with the hope of developing commercial hybrids (Lee et al, 1994). Male‐sterile, female‐fertile lines also have been used as a means to develop intermated populations in mass recurrent selection programs (Burton et al, 1990; Lewers and Palmer, 1997). The use of male‐sterile, female‐fertile lines with the objective of developing hybrid soybeans for commercial planting still remains a possibility.…”

Day Temperature Influences the Male‐Sterile Locus ms9 in Soybean

et al. 2012

Cultivated soybean [Glycine max (L.) Merr.] is a major source of oil and protein in global food production. As demand for soy‐based products increases, it is essential for breeders to find ways to increase yield beyond conventional methods. Alternative methods of cultivar development and improvement must be identified. Our objectives were to determine if the ms9 locus conferring male sterility in soybean was environmentally sensitive and, if it were, to determine which environments could be used in hybrid seed production. This was accomplished through characterization of pollen phenotypes and selfed seed set among progeny of soybean genotype T359H (Genetic Type Collection number T359H), a heterozygous maintainer line for the ms9 locus. T359H was evaluated in seven environmental regimens in growth chamber experiments. We used a split‐plot design to test the effect of temperature regimens and male‐sterile phenotypic classifications within chambers. As day temperature increased from 30 to 35°C, selfed seed set on male‐sterile, female‐fertile plants decreased. Conversely, night temperature affected neither fertile nor male‐sterile, female‐fertile selfed seed set. This suggests that ms9 can be used in hybrid seed production in controlled environments where day temperature is 35°C during the flowering. These temperature conditions and their effect on ms9 may provide an alternative method to produce hybrid seed in soybean cultivar development programs.
