ABSTRACT
One way to increase rice productivity in tidal lands containing salinity stress
(NaCl) using characters tolerant varieties. This research was conducted for 6
months, from July to December 2017 in Kreongan Village, Patrang Subdistrict,
Jember Regency. This research uses Non Factorial Random Block Design (RAK)
with 1 factors and 4 replications. Varieties treatment used were Inpari 42 (V1),
IPB 3S (V2), IR64 (V3), Ciherang (V4), Mekongga (V5), IR66 (V6), and Sintanur
(V7). The result of the research on soil containing 5303,45 ppm of salinity stress
showed that qualitatively all varieties match the description. While quantitatively
showed that the varieties has significant effect on the vegetative plant height, and
has real hight significant effect on the plants level tolerance, generative plant
height, leaf flag length, length of panicle, number of grain each panicle, number
of pithy grains, weight of 1000 grains, number of tillers, number of productive
tillers, production each hectare, yield potential, germination capacity,
germination speed and seed germination sequential. The results showed that the
Inpari 42, IPB 3S, IR64, Ciherang, Mekongga, Sintanur are tolerant varieties and
IR66 is moderately tolerant. Sintanur variety showed the best result in production
each hectare, yield potential and seed quality. Furthermore, to obtain a suitable
new type of rice on the salinity stress (NaCl) can be done genetic diversity by
crossing method.
