“…Similar results found in this study using UBC 834 primer were obtained in a study on estimative genetic diversity among 16 physic nut accessions with ISSR markers, with percentage of polymorphism equal to 57% (Camellia et al, 2012). However, in a study on the correlation of phenotypic and genetic diversity, 35.7% polymorphism was obtained using the primer UBC 809 (Sunil et al, 2011), which is much lower than that observed in this study.…”

ABSTRACT. Physic nut (Jatropha curcas L.) presents high oilseed yield and low production cost. However, technical-scientific knowledge on this crop is still limited. This study aimed to evaluate and estimate the genetic variability of hybrids obtained from dialell crossing. Genetic variability was carried out using ISSR molecular markers. For genetic variability, nine primers were used, and six were selected with 80.7% polymorphism. Genetic similarity was obtained using the NTSYS pc. 2.1 software, and cluster analysis was obtained by the UPGMA method. Mean genetic similarity was 58.4% among hybrids; the most divergent pair was H1 and H10 and the most similar pair was H9 and H10. ISSR PCR markers provided a quick and highly informative system for DNA fingerprinting, and also allowed establishing genetic relationships of Jatropha hybrids.

“…About two thirds of our 42 F 2 plants had oil content ranging from 31-40%. Based on the earlier reports, seed oil contents of J. curcas accessions varied from 17.4% in Malaysian accessions 27 , and 17.5% in Indian accessions 28 , to 64.3% in Chinese accessions 29 , and 64.5% in 72 accessions from 13 countries 17 . Oil contents of nontoxic Mexican and toxic Indian J. curcas were from 35.4-40.7% 30 , showing less variation than those from interspecific hybrids.…”

Jatropha or physic nut (Jatropha curcas) is being genetically improved in many countries for commercial plantation as a source of biodiesel. This study investigates the variation in physicochemical properties of seed and oil obtained from F2 plants of a cross between J. curcas cv. "Chai Nat" and J. integerrima (a local dwarf ornamental type from Thailand). The results revealed a high diversity in properties of seed and oil showing a number of promising genotypes. Out of 296 F2 plants derived from an F1 plant, 42 of them showed small canopy size, high in seed yield, oil content, and oleic acid content, but low in linoleic acid content. Some plants showed a kernel to seed weight ratio of more than 0.8. Some plants had over 40% seed oil content. Phorbol ester content of their seeds varied from 0.7-4.6 mg/g, with an average of 1.9 mg/g. Seed yield of the F2 plants showed a positive correlation with oil yield per plant (r = 0.99), while there were weak relationships between oil content with the other traits. A highly negative correlation was observed between oleic and linoleic acids (r = −0.97).

ABSTRAKPotensi produksi jarak pagar (Jatropha curcas L.) provenan Improved Population (IP) merupakan hasil prediksi dari produksi individu tanaman terbaik pada umur satu tahun dari suatu populasi tanaman. Sampai saat ini produksi jarak pagar secara aktual masih jauh lebih rendah dari potensinya. Keragaman tanaman diduga menjadi salah satu penyebab kesenjangan tersebut. Penelitian yang bertujuan untuk mengidentifikasi keragaman pertanaman IP-3A dilakukan pada Agustus-Desember 2010 di Kebun Percobaan Asembagus, Situbondo. Pertanaman IP-3A berumur 2 tahun, baik yang berasal dari benih maupun setek diambil 75 contoh ta-naman untuk diamati pertumbuhan dan produksinya. Data yang diperoleh dianalisis keragamannya. Hasil penelitian menunjukkan bahwa pertumbuhan tanaman dan produksi biji per tanaman jarak pagar IP-3A, baik yang berasal dari benih maupun setek, sangat beragam. Koefisien keragaman pertumbuhan tanaman yang meliputi tinggi tanaman, diameter kanopi, diameter batang, dan panjang per ruas batang lebih kecil dari 20%, sedangkan jumlah daun, diameter batang utama, panjang batang, volume batang, jumlah ruas batang, dan volume per ruas batang berkisar 20-50%. Koefisien keragaman komponen produksi yaitu jumlah tandan berbuah, jumlah buah per tandan, dan jumlah buah per tanaman berkisar 50−160%. Koefisien keragaman produksi biji berkisar 98−160% dengan produksi maksimum sebesar 4,30−8,55 kali produksi reratanya. Keragaman produksi biji yang tinggi menyebabkan adanya kesenjangan antara potensi produksi dengan aktualnya.Kata kunci: Jatropha curcas L., jarak pagar, IP-3A, keragaman, populasi, pertumbuhan, produksi Growth And Yield Variability of Jatropha IP-3A Plant Population ABSTRACTPotential yield of Improved Population (IP) provenances were predicted from the best yield of individual plants in one year old population. In the field, actual yield of jatropha is lower than its potency. The high variability in plant population may cause the divergence of the yields. A research to find out production variability of IP-3A was conducted from August to December 2010 at Asembagus Experimental Station, Situbondo. Seventy five sample plants were taken from IP-3A plantation aged 2 years from seedling and stem cutting. The sample plants were observed for their growth and yield. Variability analysis was used in this research. The result showed that plant growth and yield of jatropha IP-3A plantation, both from seedling and stem cutting were varied. Coefficient variability of plant growth including plant height, canopy diameter, stem diameter, and stem length per internode was less than 20%, whereas those of number of leaves, main stem diameter, stem length, stem volume, number of stem internodes, and volume of stem internodes ranged from 20−50%. The coefficient variability of yield components, including number of fruit bunches, the number of fruits per bunch, and number of fruit per plant ranged from 50−160%. The coefficient variability of yield ranged from 98-160%, which is 4.30 to 8.55 times of the average yields. The high vari...
