Inheritance of fertility restoration of cytoplasmic male sterility in indica rice
1985
Huang, C.S. | Tseng, T. | Liu, C.
Two indica rice crosses between Zhen Shan 97 (WA)A and restorer lines were used in this study. The F1's that were fertile had a normal stainable pollen ratio. The spikelet fertility of the F2's segregated in a ratio of 3:1, indicating that the action of fertility restoration is sporophytic and that at least a single dominant gene is involved. Linkage between the fertility restorer and the color of the lemma napalea E had a recombination value from 9.7% to 27.1%. No Rf plant or line that restored the Reimei (rufipogon) A cytoplasmic male sterility was recovered in the BC1 and F5 of Reimei (rufipogon) A L1R5032-6B-13-1. The F1 of this cross showed a degree of fertility restoration. When these F5 lines were testcrossed with Zhen Shan 97A, various degrees of fertility restoration occurred, including complete restoration
