Jatropha curcas L. (Euphorbiaceae) is a species grown in tropicalcountries and used for biodiesel production. Morphophysiological traits were analyzed to assess the genetic diversity in nine genotypes of J. curcas under deficit water. Seeds of plants from different populations, collected in diferente brazilian regions, were grown under two water regimes (100% and 50% tank capacity). Multivariate analysis was used to characterize genetic diversity. The UPGMA dendrogram built from the genetic distance group indicated the segregation of genotypes into five groups for growth traits and six groups for physiological traits. Then, an principal components analysis was carried out, to evaluate the pattern of character variations and then segregate the characteristics that could distinguish parental genotypes for use in plant breeding. Results showed 65.50% and 56.02% for the two first principal components of growth and physiological traits, respectively. Total root area was the most determining trait for genetic dissimilarity (18.9%) and group formation, followed by plant height (17.9%) and number of leaves (17.6%). On the other hand, stomatal conductance (gs) (24.9%) and guaiacol peroxidase (GPX) (20.9%) were the most determining physiological traits. The analysis of morphophysiological traits indicated CNPAE-298 and 299 as the most distant genotypes among the plant groups. Under water-limited conditions, total root area, plant height, gs and GPX were the most efficient traits to explain genetic dissimilarity among the genotypes, and for this reason they should be referred as a priority for further studies on genotypes selection in this species.

<p>The interest in using Jatropha curcas L. from the<br />family Euphorbiaceae for the production of biofuel is rapidly<br />growing. The research objective was to determine genetic<br />variation of several high yielding physic nuts based on their<br />morphology, agronomy, and isozyme characters. The<br />research used Completely Randomized Design with three<br />replications. The treatment was consisted of 8 genotypes i.e.<br />IP-1A, IP-1M, IP-2P, Lombok Timur, Lombok Tengah,<br />Lombok Barat, Sumbawa, and Bima. Analysis of isozyme of<br />the eight genotypes was also conducted according to 5<br />enzyme systems, i.e. peroksidase, esterase, aspartat<br />aminotransferase, malat dehidrogenase, and alcohol<br />dehidrogenase. Observation was done on qualitative and<br />quantitative characters as well as banding pattern derivedisozymes.<br />The results showed that genetic variation was low<br />when based on qualitative characters and isozyme (0-25%)<br />but relatively high when based on selected quantitative<br />characters analysis (17-81%). Analysis of combined<br />qualitative, quantitative, and isozyme characters still gave<br />low genetic variation (6-33%). Based on the quantitative<br />characters at similarity coefficient of 46% the genotypes can<br />be devided into three clusters. Improved population<br />genotypes, i.e. IP-1A, IP-1M, and IP-2P were placed in 3<br />different clusters, while other genotypes from NTB area<br />were grouped in the same cluster. Therefore, selection<br />among population of the same ecotype based on agronomic<br />characters such as yield components, yield and oil content<br />was suitable in Jatropha improvement, especially when<br />genetic variation was low. Furthermore, introduction,<br />mutation and crossing are suggested to increase genetic<br />variation of current Jatropha collection.</p>
