Cameroon Virescens Oil Palm (Elaeis guineensis) from IOPRI’s Germplasm

Abstract

In the assumption of oil palm breeders, virescens oil palm type has no real economic value. Therefore, the nigrescens is more considered. However, the virescens gives a visual cue that fruits are ripe without waiting to detach. In 2010, Indonesian Oil Palm Research Institute (IOPRI) successfully planted an open-pollinated population of Cameroon oil palm. The population was characterized for virescens type frequency, as well as the bunch components, quantity and quality of crude palm oil. The virescens frequency per accession was sufficiently wide, ranging from 3.33-65.71%, and was affected by the parent type, nigrescens or virescens. Most of the virescens's fruit form is observed to be of dura, except one sample, which was observed to be tenera. The mesocarp to fruit (MF) and industrial extraction ratio (IER) percentage are similar to the nigrescens dura, namely 37.7% and 9.5%, respectively. Its oil quality is better than nigrescens, and it has total carotene ranging from 155-1246 ppm. The oleic fatty acid is higher than 50%, and the palmitic is lower than 40%. Due to the ease of determining mature fruits, as well as the higher oil quality, virescens oil palm type is recommended to be introgressed in a breeding program.

Towards the fourth decade of IOPRI’s oil palm clones: Upcoming new variety

“…The database program consists of master data, ortet identification, entire laboratory processes, and a summary of all data. The clonesproduced were tested in the field with the first planting in 2013 and continued with the next test in 2015 [33].…”

Keragaman Genetik Varietas Kelapa Sawit (Elaeis guineensis Jacq.)

“…Diantara ketiga perbedaan warna buah kelapa sawit tersebut, jenis yang paling umum ditemukan yaitu nigrescens. Jadi yang paling sering digunakan untuk menciptakan jenis baru berasal dari indukan nigrescens dan virescens (Siregar et al, 2020). Variasi genetik virescens lebih luas dibanding jenis lain.…”

Gagasan: Akselerasi Pemuliaan Kelapa Sawit Virescens Memanfaatkan Teknologi Genome Editing Dan Nano Partikel

“…Hal ini disebabkan perubahan warna menjadi oranye terang lebih mudah dilihat saat mengidentifikasi buah matang dari kejauhan dibandingkan nigrescens yang berwarna ungu gelap kemerahan. Oleh karena itu, kriteria matang panen jenis buah nigrescens adalah sejumlah buah lepas dan jatuh ke tanah yang menyebabkan potensi kehilangan hasil dan pekerjaan tambahan untuk mengumpulkan buah (Siregar et al, 2020;Mohd Ramadhan et al, 2021).…”

“…Kelapa sawit virescens menunjukkan warna buah oranye pekat pada tandan matang dan warna buah hijau pekat pada tandan mentah. Tandan buah segar virescens (a); berondolan virescens (b); berondolan nigrescens (c) (Siregar et al, 2020) b a c…”
