Abstract:
Induced mutation can be used for improving quality in term of seed
production, oil content in seed and early maturity of Jatropha with the
aim for bio_diesel in Indonesia.
The doses of 10, 15,20, and 25 Gy of
gamma applied to cuttings was able to increase genetic variability in
vegetatively propagated plants of Jatropha at M1V1 (mutant-vegetative-1)
generation. Selection for desirable trait will be done at M1 V2
(mutant-1 and vegetative-2) generation untill homogenous plants
obtained. Gamma rays at dose of 20 to 25 Gy damaged several genes
controlling growth and development on Jatropha which was shown by dwarf
and poor plant growth compared to control (plant without irradiation).
Irradiation with the dose of 10 Gy raised genetic variability on plant
development which was identified with early maturity, 100 seeds weight
was 30% over control, and the number of branch growth was good.
