Water is the main factor in reducing rice yields. Tolerant rice varieties in locations with sufficient and limited water are needed to maintain rice productivity. Rice varieties that produce stable rice yields in paddy fields and dry land are called amphibious rice, but it has limited information about the traits. Therefore, the objective of the research was to examine growth response and identify amphibious traits in several rice varieties. This research used a factorial completely randomized block design (CRBD), which consisted of rice varieties and land conditions as factors. Ten commercial rice varieties originating from lowland rice and upland rice (IPB 9G, Inpago 10, IPB 3s, inpari 32, Inpari 43, Ciherang, IR 64, Way Apo Buru, Intani 605, and Mapan 05) were tested in paddy fields and dry land. The results showed that limited water in dry land causes slower rice growth, a delay in flowering age, and an increase in empty grains. NSC did not correlate with rice yields in dry land and paddy fields. The percentage of empty grains and rice yield can be used as references to identify amphibious traits in rice varieties.
