Rubber (Hevea brasiliensis L.) productivity fluctuate each year. It is caused by several factors, including rainfall, leaf fall, and clones. There are three factors are related from each other. This research aims to determine the resistance of clone after peak production and their ability to recover. The research was conducted in Afdeling Galardowo (Kebun Getas – PTPN IX) which has altitude 325-445 meters above sea level and has B climate type according to Schmidt and Ferguson. This research used descriptive analysis method with Randomized Block Design (RBD) and Duncan Range Test (DRT) which consist four treatment there are BPM 1, BPM 24, RRIM 712, and RRIC 100 clones with four replication productions in 2011, 2012, 2013, and 2014. Data analysis was carried out in June, July, August, September, October, and November. The result of this research in June and October showed significantly difference tested by DRT. Overall, BPM 24 had the highest average which indicates that it is more resistant after peak production. In addition, BPM 24 clone showed the best production recovery.
