Cytology and Genetics of a Tissue Culture-Derived Soybean Genic Male-Sterile, Female-Sterile

Genetics and cytology of a genic male-sterile, female-sterile mutant from a transposon-containing soybean population.

A male-sterile, female-sterile soybean mutant (w4-m sterile) was identified among progeny of germinal revertants of a gene-tagging study. Our objectives were to determine the genetics (inheritance, allelism, and linkage) and the cytology (microsporogenesis and microgametogenesis) of the w4-m sterile. The mutant was inherited as a single recessive nuclear gene and was nonallelic to known male-st...

Genetic identification of a female partial-sterile mutant in soybean.

We report here the genetic identification of a female partial-sterile mutant derived from soybean mutant L67-3483. L67-3483, which originated from the cultivar Clark after X-ray irradiation, is male and female fertile. All F1 plants in reciprocal pollinations of L67-3483 with 'Clark', 'Minsoy', or 'BSR 101' were female partial sterile. Partial sterility is expressed in the heterozygous conditio...

Analysis of Cytoplasmic Effects and Fine-Mapping of a Genic Male Sterile Line in Rice

Cytoplasm has substantial genetic effects on progeny and is important for yield improvement in rice breeding. Studies on the cytoplasmic effects of cytoplasmic male sterility (CMS) show that most types of CMS have negative effects on yield-related traits and that these negative effects vary among CMS. Some types of genic male sterility (GMS), including photo-thermo sensitive male sterility (PTM...
