The objective of this research was to evaluate the phenotypic behavior of 130 Jatropha curcas L. (Jatropha) accessions and the genetic variability of selected Jatropha accessions. The selected variables were assessed between 2008-2014 based on the number of fruits per tree (FP), the number of seeds per fruit (SpF), weight of 100 dry seeds (100SW), seed length (SL), seed width (SW), smallest deviation standard as regular seed production (RP), highest deviation standard as irregular seed production (IP), seed oil content (Oil), seed production in g per tree (SP). Correspondence Analysis techniques were also applied in selected elite Jatropha accessions. The genotypic and phenotypic correlation coefficient between seed length, seed width, 100-seed weight and oil content for selected Jatropha accessions were applied. Variance, genotypic and phenotypic coefficients of variation, heritability (broad-sense) and genetic advance were calculated for several Jatropha phenotypic characteristics. CP041, CP052, CP037, CP054, CP060, CP122, CP118, CP120, CP121 INIAP Jatropha accessions were selected basically for SP and FP. A high statistically significant correlation (genotypic and phenotypic) between seed length - seed width was obtained from the chosen Jatropha accessions. Genetic association in the characteristics of growth and production highlighted the low phenotypic diversity in the Jatropha Portoviejo Research Station (EEP) of the National Institute for Agricultural and Cattle Ranching Research (INIAP) germplasm bank. There is an urgent need to improve the germplasm resource by obtaining new accessions, mainly from countries considered as centers of origin of the species. 2020 artículo científico 0304-2847 https://www.redalyc.org/articulo.oa?id=179964927005 https://www.redalyc.org/journal/1799/179964927005/ https://www.redalyc.org/journal/1799/179964927005/html/ https://www.redalyc.org/journal/1799/179964927005/179964927005.epub https://www.redalyc.org/journal/1799/179964927005/movil 10.15446/rfnam.v73n3.85788 en http://www.redalyc.org/revista.oa?id=1799 Revista Facultad Nacional de Agronomía - Medellín application/pdf Universidad Nacional de Colombia Revista Facultad Nacional de Agronomía - Medellín (Colombia) Num.3 Vol.73 |
