Abstract:
Different geographic seed sources (80) of Jatropha curcas L. were collected in South China and planted in a germplasm resource garden to study their biological and agricultural properties. The average ground diameter, tree height and crown size of two-year old plants of the 80 sources was 7.6 cm, 167 cm and 114 cm, respectively, the average 1000-seed weight was 0.676 (0.477-0.876) kg. The trees grew further to the average size of 12.6 cm diameter, 2.69 m height and 2.1 m crown at the 4th year. Among the 80 sources, six sources had higher oil yield (seed oil content of 40%-42%) and better behaving in expression of phenotype were selected for a small-scale trial of forestation to determine oil yield. Among them a provenance with outstand in expression of phenotype yielded 964.3, 2000.6 and 2858.7 kg/ha was achieved for two- three- and four-year old trees, respectively. Additionally, a new Jatropha mutant was found in the wild and hybridization experiments showed that its oil content increased by 6%.
