Abstract:
The inheritance pattern of aroma in aromatic rice (Oryza sativa L.) was carried out in the four crosses among seven diversified aromatic and non-aromatic elite lines of. In four crosses viz., GR-104 × IET-26215, IET-24617 × NWGR-9081, IET-26214 × GAR-1 and IET-26215 × GNR-2, the parents viz., GR-104, IET-26215, NWGR-9081, IET-26214 and GAR-1 were aromatic, while IET-24617 and GNR-2 were non-aromatic. All the F1 plants of the four crosses were non-aromatic indicating that the gene controlling aroma in the donor parents was recessive. F₂ generations of all crosses segregated into different aromatic and non-aromatic plants. The segregation ratio of non-aromatic to aromatic plants was 3:1 in F₂ plants confirming the monogenic inheritance of aroma. These showed that there would be a high probability of success in selecting for aroma using pedigree breeding in early segregating generations of F₂.
