Inheritance of fertility restoration was studied in crosses involving ten elite restorer lines of rice viz. BR6839-41-5-1R, BR7013-62-1-1R, BR7011-37-1-2R, BR10R, BR11R, BR12R, BR13R, BR14R, BR15R and BR16R and one male sterile line Jin23A with WA sources of cytoplasmic male sterility. The segregation pattern for pollen fertility of F2 and BC1 populations of crosses involving Jin23A indicated the presence of two independent dominant fertility restoring genes. The mode of action of the two genes varied in different crosses revealing three types of interaction, i.e. epistasis with dominant gene action, epistasis with recessive gene action, and epistasis with incomplete dominance.DOI: http://dx.doi.org/10.3329/bjpbg.v24i1.16997

The two chromosomal male-sterility mutants referred to as Pugsley's male-sterile and the Probus male-sterile fail to complement one another. Partial monosomic analysis revealed that both mutants are located on chromosome 4A. A strong homoeoallelic 'echo' was received from chromosome 4B with the Probus mutant, mslb, but not with Pugsley's mutant, msla.

Nuclear Locus

Progenies (total of 1,114 seedlings) from crosses representing all possible genotypic combinations between 4 male-fertile and 1 male-sterile apricot parents were scored for the male sterility trait. Crosses between putative heterozygous normal cultivars yielded 25% of male-sterile seedlings, which supports a previous hypothesis that male sterility is controlled by a recessive allele of one nuclear locus. Crosses between those parents and putative homozygous normal cultivars did not produce any male-sterile tree. Finally, the proportion of male-sterile progeny in crosses between a male-sterile and two male-fertile cultivars depended on the genotype of the male parent. When it was heterozygous approximately 50% of the progeny was sterile, whereas when a homozygous fertile parent was used, no male-sterile progeny was obtained. These results confirm a previously proposed model, in which the male sterility trait in apricot is controlled by a single recessive gene.

Extensive Breeding

The inheritance of an induced mutant for spindly branch and male sterility (SBMS) was investigated in common bean (Phaseolus vulgaris L.) in F2 and backcross populations. The results support the hypothesis that the mutant is controlled by a single recessive gene. Extensive breeding work with SBMS, involving several thousand F2 progeny, produced no recombinant of the types expected if two closely linked genes controlled the character. Therefore, a single pleiotropic gene apparently controls SBMS. Allelism tests demonstrated that SBMS is allelic with sb but not with sb-2 and sb-3. The gene symbol sbms is proposed for SBMS because it is a new allele at sb, with the order of dominance being Sb > sb > sbms. Various ways to exploit the new mutant for marked male sterility are discussed.

Chromosome Arm

ABSTRACT The factors for Cornerstone and Probus male sterility are allelic on chromosome arm 4Aα. They map independently of the centromere, but show linkage with a rye segment located 1 crossover unit from the centromere on the β arm. The alien segment causes asynapsis and some precocious terminalization of chiasmata when in repulsion with the mutants. The mutants, presumed to be terminal deletions, cause some desynapsis, but not asynapsis.

Hybrid Seeds

The utilization of heterosis is an important way to improve wheat yield, and the production of wheat hybrid seeds mainly relies on male-sterile lines. Male sterility in line 15 Fan 03 derived from a cross of 72,180 and Xiaoyan 6 is controlled by a single recessive gene. The gene was mapped to the distal region of chromosome 4BS in a genetic interval of 1.4 cM and physical distance of 6.57 Mb between SSR markers Ms4BS42 and Ms4BS199 using an F2 population with 1205 individuals. Sterile individuals had a deletion of 4.57 Mb in the region presumed to carry the Ms1 locus. The allele for sterility was therefore named ms1s. Three CAPS markers were developed and verified from the region upstream of the deleted fragment and can be used for ms1s marker-assisted selection in wheat hybrid breeding. This work will enrich the utilization of male sterility genetic resources.

Male Sterility Gene

Mutations that result in plant male sterility provide means not only to probe reproductive development but also to facilitate commercial heterosis application and hybrid seed production. In this study, we report a novel male sterility gene, ms91(t), in a spontaneous mutant line (SH38) from a Chinese rice cultivar (Oryza sativa subsp. japonica ‘Jijing14’). The sterility of SH38 was studied by examining its progenies derived from crosses with 6 japonica cultivars. Corresponding F2 populations were obtained by selfing each of the 6 F1s and a backcross population was produced by crossing SH38 to the F1 of SH38 × C18. Our results revealed that SH38 has normal agronomic traits but produces no pollen grains. Segregations of male-sterile and male-fertile progenies in the F2 and backcross populations fit well with ratios of 3:1 and 1:1, respectively, indicating that ms91(t) is a single recessive gene. Amplified fragment length polymorphism (AFLP) analysis of SH38 and Jijing14 plants showed the presence of a unique band in SH38. Simple sequence repeat (SSR) analysis of the bulked and individual progenies of the F2 population of SH38 × C18 showed linkage of ms91(t) with the SSR marker RM5853 on chromosome 1. Subsequently, ms91(t) was fine-mapped to the interval between markers RM7075 (3.75 cM) and RM5638 (3.57 cM). Our results would facilitate the isolation of ms91(t) and male sterility in heterosis application.

X Triticosecale Wittmack

The difference in height between a chemically-induced (EMS) semidwarf mutant of hexaploid triticale (X Triticosecale Wittmack) and its tall parent (6TA204) was found to be controlled by a single recessive gene. The pedigree of the 6TA204 parent involved the combination of two hexaploid triticales, one octoploid triticale, and one dwarf hexaploid wheat (Triticum aestivum L. em. Thell). The dwarfness of the hexaploid wheat (P41603E), itself known to be conditioned by one or more recessive genes, was masked in the 6TA204 parent. In the derivation of the semidwarf 6TA204, it is postulated that either (1) a dominant gene for tallness was mutated to the recessive state, or (2) that a suppressor gene closely linked with a recessive gene for semidwarfism was impaired by EMS treatment, thereby allowing the expression of the semidwarf condition. Spike length of the semidwarf remained comparable to that of the tall parent; however, its cytological stability and fertility were significantly lower.

Moderate Resistance

The inheritance of stem rust (Puccinia graminis f. sp. tritici Eriks. and Henn.) resistance was studied in 'K253', a hexaploid wheat (Triticum aestivum L.) with resistance derived from a tetraploid wheat (T. turgidum L.). The studies indicated that 'K253' carries one dominant gene for good resistance to races 29 and 56 (probably Sr9e) and one recessive gene for moderate resistance to race 15B-1. In addition, some plants apparently carry a recessive gene for moderate resistance to race 56. Four different types of hexaploid near-isogenic lines were produced. One carried Sr9e and another the gene for moderate resistance to race 15B-1. Two carried genes that had not been identified in the genetic studies, including one that was apparently not derived from K253.Key words: stem rust resistance, Puccinia graminis tritici, wheat, Triticum aestivum, Triticum turgidum.
