Resumen
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.
