Genetics of thermosensitive genic male sterility in rice
Euphytica, 1996Inheritance of thermosensitive genic male sterility (TGMS) in Norin PL12 and IR32364TGMS and their allelic relationship were studied from F1, F2 testcross (TC) and F3 generations of the crosses made with the two mutants and several fertile tester parents. F2, TC and F3 segregation behavior for pollen and spikelet fertility indicated that the TGMS trait

Analysis of genic male sterility in Brassica oleracea
Euphytica, 1993The male sterility system MS-1 of Brassica oleracea was studied in order to elucidate if nucleo-cytoplasmic interactions determine this system. Crosses of male sterile MS-1 genotypes with heterozygous MS-5 genotypes gave fully fertile F1 progenies. Selfing of seven F1 plants resulted in five F2 populations showing a 9:7 segregation ratio and two a 3:1 ...

Progress on genic male sterility gene in soybean.
Yi chuan = Hereditas, 2021Male sterility refers to the phenomenon that stamens cannot grow normally and produce viable pollen grains in plants. Hybrid seed production by taking advantage of the trait of male sterility is an effective and quick strategy to increase crop yield. Up to date, the yield of rice (Oryza sativa L.), maize (Zea mays L.), wheat (Triticum aestivum L.) and ...

Cytokinins in a genic male sterile line of Brassica napus
Physiologia Plantarum, 1992Endogenous cytokinin levels were analyzed in four different organs viz., root, stem, leaf and mature flower, of the wild type (cv. Westar) and a genic male sterile (GMS) line of Brassica napus. Various cytokinins viz., bases (Z, DZ), ribosides (ZR, DZR), glucosides (OGZ + OGZR, OGDZ + OGDZR) and nucleotides (ZNT, DZNT) were quantified using Amaranthus ...

Photoperiod-sensitive genetic male-sterile (PSGMS) rice, with its male fertility regulated by photoperiod length, is very useful for hybrid rice development. However, breeding for new PSGMS lines has faced two major difficulties - the stability of male sterility and the reversibility of male fertility.

Planta, 2003
The tapetum plays a crucial role in pollen development. This secretory tissue produces numerous nutritive proteins necessary for pollen maturation. The tapetum, whose cells undergo programmed cell death (PCD), is completely diminished by the time the pollen is fully mature. Our previous studies on a thermosensitive genic male-sterile (TGMS) rice (Oryza

Genic Male Sterility (g-mst) is of a wide occurrence in flowering plants and the majority of the steriles have arisen as spontaneous mutants (Table 2.1). Only a few have been induced after mutagen treatments (Table 2.3). In about 175 species in which mst has spontaneously arisen, the majority are dicots in species as well as in species crosses (Fig.

Cytochemical investigation of genic male-sterility in Chinese cabbage
Sexual Plant Reproduction, 2005A genic male sterile Chinese cabbage, Brassica campestris L. ssp. chinensis Makino, was examined using cytological and cytochemical methods to characterize the process of pollen abortion in this plant. Thick sections of both fertile and sterile anthers at different developmental stages were stained using Toluidine Blue O, Periodic Acid-Schiff’s (PAS ...

Molecular markers for genic male sterility in Chinese cabbage
Euphytica, 2003The gms gene of Chinese cabbage (Brassica campestris ssp. chinensis) conferring a recessivegenic male sterility was mapped with AFLPmarkers. Four markers were found to betightly linked to the gene with a distanceof

Analyses of a genic male-sterile mutant in soybean
2018Genetic and cytological studies were conducted with a new male-sterile, femalefertile soybean [Glycine max (L.) Merr.] mutant. This mutant was completely male sterile and was inherited as a single-recessive gene. No differences in female or male gamete transmission of the recessive allele were observed between reciprocal cross-pollinations in the Fi or
