Rice lines potentially as new varieties for acidic dry lands

Dry land has great potential to support programs to increase national rice production by increasing the planted area. The aim of the study was to evaluate the yield of upland rice lines to obtain several lines of upland rice which had high yield and had the potential to be released as new varieties for acid dry land. The experiment was carried out in Lampung on DS 2020. A total of 60 advanced upland rice lines and comparison varieties were used as material for this experiment. The variables observed were plant height, number of productive tillers, age of flowering plants (50%), harvestable age (80% yellowing of rice), number of filled and empty grains per panicle, weight of 1000 filled grains, yield. milled dry grain and its resistance to biotic and abiotic stress. From the preliminary yield test, ten lines showed comparable yields above the best comparison variety Inpago 12. The lines were B14986E-MR-26 (6.78 t/ha), B15151E-MR-23 (6.39 t/ha), B15151E-MR-21 (6.61 t/ha), B15151E-MR-18 (5.95 t/ha), B15340 -2B-TB-23 (5.87 t/ha), B15154E-MR-2 (6.33 t/ha), B15151E-MR-1 (5.78 t/ha), B13017B-RS*1-2-6-PN-11-2-1 (5.94 t/ha) and B15511D-KR-31 (6.32 t/ha). Those lines have long (L), medium (M) and medium chalkiness (M) sizes. The rice texture is between medium and soft.
