Abstract
The objective of this experiment was to study on vegetative growth, heritability, and correlation in seedling stage of oil palm hybrid variety SUB PSU 1, a total of 27 crosses derived from the crossing between one male pisifera and different female dura parents namely No. 31, 52, 59, 69, 81, 96, 106, 118, 129, 136, 142, 155, 171, 177, 184, 201, 203, 207, 222, 227, 229, 230, 232, 237, 239, 240 and 202 / 6. The experiment was carried out at the Faculty of Natural Resources, Prince of Songkla University during May 2018 - January 2019. The experimental design was CRD with collection of vegetative characteristics at 12 months after planting, five plants per cross. It was found that all characteristics were significantly different and they had a narrow sense heritability (h2) at the low-level between 0.73 - 2.36 %, as well as positive correlations on vegetative growth characteristics. In addition, it was found that 8 crosses showed good growth characteristics including; 59, 136, 142, 184, 227, 239, 240 and 202 / 6. This data can be used to select maternal dura oil palm plants for quality oil palm seedling production.
