In past five years from 1984 to 1988, 48 cases of male sterile (ms) mutants in nine varieties were found, in which 30 cases belonged to R_1 generation and 28 to R_2 generation. The frequency of ms variation in R, generation was around 1% and 2% in R_2 generatiom. According to the characters of ms-mutants and their genetic expressions,pollen grain free(nuclear sterile) and abortive pollen (cytoplasmic genetic sterile) could be classified, In 1R54, two cases of pollen grain free ms-mutants were…

A new excellent cytoplasmic type of cytopLasmic male sterile (CMS) line (S10-2A) has been developed from Minghui 63, and One exceptional restorer line was obtained form the fertile revertants of Baoyuan A and Hongyuan A by means of genealogical method, respectively.

Male Sterile Mutants from Rice Somaclones

The new cytoplasmic male sterile (CMS) lines with non-WA cy toplasm have been studied and developed for a long time and some shortcomings can be found in WA-type cytop lasm such as poor disease/insect resistance and low quality.

Cytoplasm and cytoplasm-nucleus interactions affect agronomic traits in japonica rice

Results indicated that cytoplasm and cy toplasm-nucleus interaction played important roles in yield, low temperature tolerance, and some important agronomictraits in japonica rice.

The establishment of in vitro culture and genetic transformation of the wheat Glu-1Dx5 gene to rice plants by gene gun bombardment

Four indica types, Fatmawati, Ciapus, BP-23 and BP-360-3, had callus induction-related traits similar to those of Nipponbare and would be useful for tissue-culture based research and for crop improvement program, particularly for genetic transformation.
