Abstract:
The aim of this study was to determine the genetic diversity in accessions of Jatropha curcas located in the Mexican germplasm collection. Mexican collection has 400 germplasm accessions and is located in the municipality of Tuxtla Chico, Chiapas to 400 meters above sea level under humid tropical conditions. In this collection was conducted agronomic characterization, morphological and molecular. The results showed differences among accessions. The variation in yield of fruit was 3 grams to 2.6 kilograms per tree. The average male to female flower ratio was 12:1, however it was detected trees with flowers completely pistillate. Morphological characterization was carried out in 90 accessions using 68 descriptors of leaf, flower, fruit and seed. The results showed that variation is reflected by the shape of leaf, fruit and seed and the weight of fruit and seed. Molecular characterization was based on Mexican germplasm comprising 88 accessions using 6 primer of AFLP (Amplified Fragment Length Polymorphism) and 16 primer SSR (Simple Sequence Repeat) markers. This study revealed high genetic diversity over 70%. We conclude that there is considerable genetic diversity in germplasm Jatropha Mexican which extends the possibility of obtaining new varieties with desirable agronomic and industrial characteristic.
