Abstract

The red colour of rice is confined entirely to the pericarp and this is lost partially or completely when rice is subjected to various degrees of polishing, after husking. Independent segregation of red and white rice has been observed in cross progenies by several workers. Parnell (1917), Hector (1913), McKerral (1913), Thompstone (1915) and Van der Stock (1912) have all recorded a simple 3: 1 ratio of red to white rice. Lien Fang Chao (1928) has however recorded as 15: 1 ratio of red to white in addition to 3: 1. During the season of 1931-32 a cross was made between T. 322 having long panicle and white rice and T. 206 with short panicle and red rice, with the object of studying the correlation between panicle length and yield, and incidentally the rice colour was studied in the progenies. The F₁ generation was pure for red rice. The F gener- ation showed segregation for rice colour and the following results were obtained.
