Daftar Isi:
- Keyword : Karakterisasi, Morfologi, Tanaman Jarak Pagar. Abstraksi Jarak pagar merupakan salah satu tanaman yang potensial sebagai penghasil minyak nabati. Dalam rangka mendukung pengembangan jarak pagar untuk menyediakan varietas unggul dengan produktivitas tinggi perlu dilakukan karakterisasi sebelum melakukan pelepasan. Penelitian ini bertujuan untuk mendapatkan informasi tentang karakter morfologi beberapa nomor hibrida jarak pagar dan tetua persilangan persilangan jarak pagar dan informasi tentang similaritas antar hibrida dan tetua persilangan jarak pagar. Kegiatan penelitian ini dilaksanakan di Desa Kepuharjo Kecamatan Karangploso Kabupaten Malang pada Oktober 2014 - Agustus 2015. Penelitian dilakukan dengan mengamati karakter morfologi empat nomor hasil persilangan jarak pagar yaitu 5.1.14 (SP 8 x SP 16), 6.2.10 (SP 8 x SP 38), 7.2.8 (SP33 x HS 49), 18.1.14 (SM 35 x SP 38) dan enam tanaman tetua antara lain HS-49, SP-8, SM-35, SP-33, SP-16, SP-38 serta dua tanaman perbandingan yaitu, IP-3A dan IP-3P. yang meliputi morfologi batang, daun, bunga, buah dan biji. Hasil penelitian menunjukkan antar genotip terdapat keragaman pada sifat-sifat diameter batang, sudut percabangan, warna daun muda, warna daun tua, percabangan pada tangkai bunga dan rata-rata panjang tangkai buah. Tanaman hasil persilangan 5.1.14 memiliki kemiripan dengan tetua jantan (SP-8) sebesar 75% dan tetua betina (SP-16) sebesar 75%; 6.2.10 memiliki kemiripan dengan tetua jantan (SP-8) sebesar 60%-65% dan tetua betina (SP-38) sebesar 60%-65%; 7.2.8 memiliki kemiripan dengan tetua jantan (SP-33) sebesar 70%-75% dan tetua betina (HS-49) sebesar 60%-65%; 18.1.14 memiliki kemiripan dengan tetua jantan (SM-35) sebesar 85%-90% dan tetua betina (SP-38) sebesar 85%. Jatropha curcas L. is a plant that is potentially as vegetable oil. In order to support the development of jatropha to provide improved varieties with high productivity needs to be characterized before release. This study aimed to obtain information about the morphological characters of some number of hybrid Jatropha and Jatropha hybrid crosses elders and information about the similarity between hybrid and hybrid Jatropha elders. The research activities carried out in the village Kepuharjo Karangploso District of Malang Regency in October 2014 - August 2015. The study was conducted by observing morphological characters of four numbers of crossbred Jatropha namely 5.1.14 (SP 8 x SP 16), 6.2.10 (SP 8 x SP 38), 7.2.8 (SP33 x HS 49), 18.01.14 (SM 35 x SP 38) and six elders among other crops HS-49, SP-8, SM-35, SP-33, SP-16, SP -38 as well as two plants that comparison, IP and IP-3A-3P. which includes morphological stems, leaves, flowers, fruits and seeds. The results showed that there are variations among genotypes on the characters of stem diameter, branching angle, the color of young leaves, the color of old leaves, flower stalks and branches on the average length of the fruit stalk. Crop yields crosses 05/01/14 resemblance to the male elders (SP-8) by 75% and female elders (SP-16) by 75%; 6.2.10 has similarities with the male elders (SP-8) by 60% -65% and the female elders (SP-38) of 60%-65%; 7.2.8 has similarities with the male elders (SP-33) by 70% -75% and the female elders (HS-49) of 60%-65%; 01/18/14 resemblance to the male elders (SM-35) of 85%-90% and the female elders (SP-38) amounted to 85%
