INHERITANCE OF FERTILITY RESTORATION INVOLVING WILD ABORTIVE CYTOPLASMIC MALE STERILITY SYSTEM IN RICE (Oryza sativa L.)
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 t...
متن کاملMitochondrial comparative proteomic analysis of sterile line and its maintain line of purple cytoplasmic rice (Oryza sativa)
CMS/Rf systems in rice (Oryza sativa) have long been exploited for hybrid breeding to enhance productivity. Ying xiang CMS/Rf system is a new type. In this study, a mitochondrial comparative proteomic analysis of Ying xiang Sterile Line and its Maintain Line was started for a comprehensive investigation of the mitochondrial proteins’ functions in rice cytoplasmic male sterility. Mitochondria we...
متن کاملThe Possible Role of Atp6 Gene in Cytoplasmic Male Sterility in WA (Wild Abortive) Type of Rice (Oryza sativa L.)
The possibility of occurrence of some rearrangements inside and or around coxII and atp6 genes and their relationship with male sterility in rice lines having wild abortive (WA) cytoplasm was studied. Two sterile (IR58025A and IR62829A) and two maintainer lines (IR58025B and IR62829B) were used. Radioactive Southern blotting was employed to carry out the experiments. The hybridization of coxII...
متن کاملWhole mitochondrial genome sequencing and transcriptional analysis to uncover an RT102-type cytoplasmic male sterility-associated candidate Gene Derived from Oryza rufipogon.
Cytoplasmic male sterility (CMS) is a maternally inherited trait in which plants fail to produce functional pollen and is associated with the expression of a novel open reading frame (orf) gene encoded by the mitochondrial genome. An RT102A CMS line and an RT102C fertility restorer line were obtained by successive backcrossing between Oryza rufipogon W1125 and O. sativa Taichung 65. Using next-...
متن کاملMapping QTLs for Fertility Restoration of Different Cytoplasmic Male Sterility Types in Rice Using Two Oryza sativa ×O. rufipogon Backcross Inbred Line Populations
Hybrid rice breeding using cytoplasmic male sterility/fertility restoration (CMS/Rf) systems plays an important role in ensuring global food security. Two backcross inbred line (BIL) populations derived from either Xieqingzao B (XB)//XB/Dongxiang wild rice (DWR) (XXD) or XB//DWR/XB (XDX) were used to detect quantitative trait loci (QTLs) for fertility restoration of Dwarf wild abortive- (DA-), ...
