【 摘 要 】

Sampoerna Agro and NEIKER perform jointly since many years collaborative R&D projects related to Molecular breeding and Marker assisted selection in Oil palm in order to accelerate the oil palm breeding program and to improve its efficiency. The detection of candidate genes for useful traits offers the possibility to apply them - after developing the corresponding markers - in marker assisted selection (MAS) within breeding programmes. The survey of the allelic diversity of such genes in available germplasm and the analyses of their particular effects permits to select the most efficient alleles or allele combinations for these purposes. Within this project, we have identified useful candidate genes for different productive and quality traits as well as for stress tolerance using different molecular tools. We have characterized the allelic variation in this germplasm in order to develop marker assisted breeding strategies through Model building. The developed Models which show large correlations between predicted and observed values explaining large portions of the total variance can be used to assign breeding values to parents and to predict progeny performances of their crosses. In this paper, we summarize the R&D activities which are being performed and practically implemented at Sampoerna.
