Abstract


The research has been done in ± 54 high sea level at Balai Penelitian Sungei Putih, Pusat Penelitian
Karet, Galang, Deli Serdang-North Sumatera Province. The research held in February until July
2012. The objective of this research to get the best progeny based on potential of latex yield
characteristic and timber yielding of crossing result 2001-2003. This research is done by measuring
mean value, maximum value, minimum value, range, class, interval, correlation, 10% and 1%
selection intensity. The research used to 1013 progeny on nine years old.
Based on selection as latex with 10% selection intensity found 86 progeny, and 1% selection
intensity there are 34 progeny, and found 5 progeny can developed directly because have
production above 30 g/t/t. In hence, timber yielding progeny with 10% selection intensity there are
132 progeny, and 1% selection intensity got 34 progeny. 15 progeny with 10% selected intensity as
latex and timber yielding namely: 13/01/A, 86/02/B, 41/01/A, 331/01/A, 57/01/A. 577/01/A,
639/01/A. 45/02/B, 671/01/A, 239/01/A, 619/01/A, 160/01/A, 139/01/A, 195/01/A, and 423/01/A
and 1% selection intensity there are 3 progeny i.e. 139/01/A. 195/01/A, and 423/01/A.
Key words : Hevea brasiliensis, hand pollination, selection, progeny.
