Abstract

Pratama et al, 2018. Oil Palm Breeding Program Strategy for Suboptimal Area in PT Binasawit Makmur  . JLSO 7(1):26-36. Suboptimal areas have great potential to be used an alternative land for cultivation of oil palm.We needed superior oil palm material to be able to grow well on that land. PT. Binasawit Makmur (BSM) through the Breeding Unit has developed a strategy regarding the assembly of superior material oil palm drought resistant. Therefore, this research aimed to develop  a strategy regarding breeding program in suboptimal lands of PT Binasawit Makmur.  The strategies used were  introducing, evaluating, and selecting genetic material based on productivity components (total and weight of fresh fruit bunches/ha, extraction rate) and high increment.  In addition, the efforts have been made to obtain drought tolerant material are conducting a progeny trial (DXP Trial) on mature palm to obtain drought tolerant in the dried season. Based on the results of the progeny trial, both of parents were traced to a crossing program. Currently, the seeds of the crossing have been obtained to confirm the results of the research on the nursery scale. In the nursery trial, research will be conducted to measure the proline content, stomata and chlorophyll content. Selection in the mature palm DXP progeny trial was followed by application a molecular tool such as SSR and SNP. Through this approach, a superior genetic material in terms of productivity and also drought tolerance can be developed and therefore can be used for recombination and release of new varieties.

Abstract

Surahman H, Sulaksono G, Sembiring Z, Kurnianingsih A, Priadi DP, Asmono D. 2020. Effect of plant gowth regulator on the gowth of zygotic embryos in three types of oil palm fruit (Elaeis guineensis Jacq.) in tissue culture. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 149-159.Embryo culture is a widely used and effective way of overcoming the dormancy nature of seeds in oil palm.  At the germination stage, the influence of gowth regulators play an important role although in relatively lower concentrations in the germination media. This aim research determined the effect of adding various concentrations of gowth regulator on the three types of oil palm fruit based on the thickness of the shell. This research carried out at the Tissue Culture Laboratory of PT. Sampoerna Ago Tbk. from September 2018 to January 2019. The gowth regulator substances used in this study were NAA, BAP and GA3. The composition of the gowth regulators used were H1 = 0.05 mg/L NAA + 0.1 mg/L BAP + 0.1 mg/L GA3, H2 = 0.05 mg/L NAA + 0.3 mg/L BAP + 0.1 mg/L GA3, H3 = 0.05 mg/L NAA + 0.5 mg/L BAP + 0.1 mg/L GA3 and H4 = No gowth regulator. While the types of oil palm fruit used were C1 = Dura, C2 = Tenera and C3 = Pisifera. This research used a factorial complete randomized design with three replications. The results showed that in general the use of gowth regulator substances H1 = 0.05 mg/L NAA + 0.1 mg/L BAP + 0.1 mg/L GA3 and the type of dura fruit showed positive results based on viability, scoring, survival and height of plantlets when compared with other treatments.
