Abstract
A breeding plot with two recommended rambutan lNepheium lappaceum Linn. clones namely R99 and R134 and another tourteen popular clones namely R3 R4 R7 RY R137 R13Y R153 R156 R157 R160 R161 R162 R168 and R170 was established at MARDI Research Station Bukit Ridan in order to obtained F1 hybrid seeds. Ten thousand open pollinated seeds trom RYY and R134 plants were COllected and established as close planting experimental plots with 7 000 F1 seedlings at MARDI Research Station Bukit Tangga in 1989. R99 and R134 were chosen as the maternal parents because almost all the agronomic characters of these clones are acceptable except for the testa that remained attached to the aril when the aril was removed. Six years later 50 of the population flowered and about 40 of them were males. Seven percent of the population flowered two weeks earlier than both parents. Less than 1 produced high quality fruits with a combination of good appearance high recovery with non-attached testa to the aril. Ten percent of the population was highly susceptible to bark borers pink disease and serious physiological disorders.Available at Perpustakaan Sultan Abdul Samad Universiti Putra Malaysia 43400 UPM Serdang Selangor Malaysia. mal SB 359 I61 1996 Vol. 1 Call Number
