“…Recently, the concept of adaptation developed into an influential research area for many fields of study (Van Aalst et al 2008;Obayelu et al 2014). It has been imperatively adapted as a policy response to the negative effects of climate change together with mitigation, therefore adaptation and mitigation had to be considered equally (Burton et al 2006;Hill 2008;Devi et al 2017).…”

Climate change is one of the multiple challenges facing all categories of farmers globally. However, African farmers are the most sensitive in respect of climate variability and change. Climate change impacted negatively on crop production and the livelihoods of the local farmers. In black township South Africa, agricultural activities are highly dominated by small-scale farmers, whose farming system is highly vulnerable to changes in climate. This paper presents the analysis of how small-scale farmers employed adaptation strategies in response to climate change and determinants of small-scale households' choices of coping and adaptation approach to climate variability and change in Vhembe District, South Africa. Multi nominal logit model was used on a surveyed of 224 local farmers. Farmers' socioeconomic attributes, was used in response to climate changes and further, households have adaptation strategies both on-farm and off-farm approach. Such approaches were; drought-tolerant seeds, shorter cycle crops, diversification of crops, changing planting dates, small-scale irrigation, migrating to urban areas and involvement in petty business. The results of the findings reveals that the significant drivers affecting choice of adaptation approach include climate information, gender, farm size, education level, farmer experience, decreasing rainfall and increases in temperature as farmers' determinant choices of adaptation to climate change. While, on the other hand, off-farm resources, headed households and age had no significant impact on the choice of coping and adaptation approach to climate change. Therefore, policy makers in the local municipality should play a significant role by enhancing adaptation strategies appropriate for particular climatic shock on the study area.

“…Instead of choosing a character (which is a result of many genetic studies), the MAS is based on the genes that provide the desired character. This is called the quantitative feature locus (QTL) the choice of specific alleles in the marker locus is dependent [13,14]. To summarize the theoretical advantages of MAS:…”

“…Penggunaan penanda molekuler untuk seleksi tanaman dapat memperpendek siklus pemuliaan tanaman dan seleksi yang dilakukan lebih valid, sehingga hanya kelapa sawit terpilih yang ditanam di lapangan. Melalui kemajuan teknologi molekuler, identifikasi dan karakterisasi gen potensial dan variasi genom yang meregulasi pertambahan tinggi batang sebagai langkah awal pemuliaan tanaman dapat dicapai (Roberdi et al, 2015;Devi et al, 2017).…”

Tanaman dengan pertambahan tinggi yang lambat merupakan karakter penting dalam program pemuliaan kelapa sawit dan brasinosteroid merupakan hormon penting yang berpengaruh untuk karakter tersebut. Gen sterol metiltransferase 1 (SMT1) merupakan salah satu gen kunci dalam biosintesis brasinosteroid. Pengembangan marker molekuler dapat dimulai dengan identifikasi dan karakterisasi gen yang terkait dengan karakter target. Penelitian ini bertujuan untuk mengisolasi dan mengkarakterisasi keragaman nukleotida gen SMT1. Amplifikasi PCR dilakukan menggunakan genom Elaeis oleifera (E.o.), E. guineensis (E.g.) dan hibrida dari keduanya (E.g. x E.o.) dengan sepasang primer spesifik gen SMT1. Dalam penelitian ini berhasil diamplifikasi satu potongan DNA gen SMT1 dan dari hasil DNA sequencing berhasil diidentifikasi sebanyak 501- 505 pb. Potongan DNA yang diidentifikasi terdiri atas partial intron 8, exon 9, intron 9, dan patial exon 10, yang menyandi antara 104-105 residu asam amino. Domain residu asam amino terkonservasi ditemukan dalam hasil translasi amplikon, yang berkorelasi dengan situs aktif dalam biosintesis brasinosteroid dan mengkonfirmasi identitas amplikon sebagai bagian dari gen SMT1. Keragaman nukleotida potongan DNA gen SMT1 yang teridentifikasi berpotensi dapat digunakan untuk pengembangan marker molekuler yang bermanfaat untuk pemuliaan tanaman kelapa sawit, terutama untuk karakter pertambahan tinggi tanaman yang lambat. Kata kunci: Brasinosteroid, sterol, tanaman kerdil
