Genetic Performance of the Semidwarfing Allele sd1 Derived from a Japonica Rice Cultivar and Minimum Requirements to Detect Its Single-Nucleotide Polymorphism by MiSeq Whole-Genome Sequencing.

ABSTRACT: The influence of the semidwarfing gene sd1 derived from the rice cultivar Jukkoku (Jukkoku_sd1) and IR8 (IR8_sd1), which contributed to the Green Revolution, d60 from Hokuriku 100, as well as the combination of sd1 and d60 (Jukkoku_sd1 plus d60 and IR8_sd1 plus d60), was investigated using isogenic lines raised by backcrossing with the cultivar Koshihikari. The isogenic lines carrying Jukkoku_sd1, IR8_sd1, d60, Jukkoku_sd1 plus d60, and IR8_sd1 plus d60 had considerably shorter culm lengths than Koshihikari by 19.2%, 22.8%, 26.0%, 45.1%, and 43.4%, respectively. The sd1 plus d60 lines showed additively reduced culms, indicating that the function of d60
