Abstract:

Many scientists have systematically studied how purple color is inherited in rice leaves. Three pairs of basic genes (C, A, P) control the inheritance of anthocyanin pigments (Nagao 1951). The C-A-P gene system in japonica rice is suitable for indica rice (Kinoshita 1984). Tongmin et al (1996) studied the inheritance of two purple rice lines and the possibility of their use as morphological markers in hybrid rice breeding.

The experiment was conducted in 2000-03 at ACRI. The genotypes involved in the crosses were aromatic rice varieties (ADT41,Pusa Basmati 1, and Basmati 370), nonaromatic varieties (ADT39 and AD98028), and a nonaromatic TGMS line (TS29) with purple basal nodes.
