We aimed to assess survival rate of grafted-seedling of local Durian (Durio zibhetinus) in the Osingnese orchards Banyuwangi. This study mapped the location of wild seedling distribution, grafting of durian seedling, and evaluating the survival rate of grafted-seedling growth. Wild seedling mapping used GPS and coordinates of seedling and analyzed spatially using QGIS 2.8. Individual rootstock for grafting was selected from wild seedling in types of open and close canopy orchards. Grafting experiment used three red durian variants: DB, RX, and BMS as scion. Each orchard experiment 6 grafting treatments and 5 repetitions. Survival rate was observed every 2 weeks after grafting. Survival rate compared the percentage of living and dead scion. Growth models was analyzed by multivariate Clusters and biplot on PAST. The best percentage of scion survival rate shows by DB variant in the first orchard under close canopy (80%) and BMS in the third orchard in close canopy (60%). Adaptation analyzed by scion characters growth consists of three groups. The less adaptive character (first group): BMS-K₁-O, BMS-K₂-C, BMS-K₂-O, BMS-K₃-O, DB-K₂-O, DB-K₃-O, RXK₁-O,RX-K₂-O, and RX-K₃-O. Second, group of adaptive character: DB-K₁-O, DB-K₂-C, DB-K₃-C, RX-K₁-C, RX-K₂-C, RX-K₃-C, and BMS-K₁-C. Third group with more adaptive character includes DB-K₁-C and BMSK3C.
