Inbreeding is a common method used to reproduce candidate mother plant from selected parental lines for commercial seeds in Reciprocal Recurrent Selection (RRS) oil palm breeding program. However this practice may increased homozigosity level of population. This study concerned the homozygosity SP540T fourth generations and Dura Deli Dolok Sinumbah fifth (3 crosses respectively) their correlation with inbreeding depression symptoms. Polymerase Chain Reaction-Simple Sequence Repeat (PCR-SSR)...

The oil palm breeding program for the species Elaeis guineensis and backcross oleifera is running slowly because an annual plant. Therefore, it necessary to have alternative approach that can accelerate program. SNP (single nucleotide polymorphism) genome-wide was then used study association between 18 phenotypes of bunch component in germplasm E. from Suriname Brazil Coari, some interspecific hybrids elite progeny guineensis. genotyping by sequencing (GBS) analysis produced a total 459...
