Based on amylose content determination done on single grain of rice, the present experiment aimed at elucidating the mode of inheritance of amylose content of rice crosses and their reciprocal including F1, F2, F3 generations. Ths results indicated that the gene dosage effect only existed in parts of the crosses and their reciprocal, in the crosses of high/low and middie/low amylose content hsren (indica) rice variety, a single major gene in association with modifying genes governed the inheritance of amylose content, high and middle amylose content was completely dominant over low amylose.
