| Popis: | Objective: To characterize different provenances of Jatropha curcas L., introduced and collected, through morphoagronomic indicators, in order to select those with the best performance. Materials and Methods: The study was conducted during one year (2019) in areas of the Pastures and Forages Research Station Indio Hatuey. The work was done with plant material from Paraguay, Ecuador and eastern Cuba. The different Jatropha curcas L. provenances were propagated by seeds. The indicators height, number of branches, stem diameter, quantity of racemes and their length, quantity and length of inflorescences, quantity of fruits and their sizes, were measured, among other variables. The data were processed through the principal component (PCA), cluster and correlation analyses. Results: Of the variability, 96,8 % was explained through four components. The fruit quantity, length and width, quantity of seeds and their sizes, as well as quantity of inflorescences and stem diameter were the indicators with which 55,6 % of the variability was explained in the first two components. Five groups were formed. The second was the one with the best performance in six of the evaluated indicators. Conclusions: There is variability for the evaluated morphoagronomic traits. The provenance Ecuador 2 was the one with the best performance in six of the evaluated indicators. It was followed by Paraguay 2 in four indicators, for which both were selected and turned out to be promising for their study in future breeding programs. |
