The Bionic Jatropha breeding program in 2012

Since we started our JcL breeding program we focused primarily on elite non-toxic hybrid cultivars. We have completed the main phase of a proof of concept (PoC) meant to significantly reduce the commercial risk involved in a full scale program go ahead.

By the end of 2011 we have succeeded in showing the validity of all three of our principal approaches, one involving traditional intra specific hybridization, one an already well documented inter specific hybridization path and one a completely innovative bottom up inter specific hybridization method.

We have recently decided, to add a 6 months extension to the PoC to gather more useful planning data especially by reaching the third generation of hybrid breeding, but also by further verifying and confirming protocols developed over the last 18 months.

During the PoC we have worked with 5 different toxic JcL accessions from Africa and Asia as well as 4 distinct non-toxic accessions from the center of origin and a number of accessions from 2 related species. All that parental material has been used to establish a stable, mature selection of germplasm ready to be used in larger scale breeding approaches.

We have also expanded our carefully selected population of parental material for further breeding by another 8 unique non-toxic and 15 toxic JcL accessions. Especially useful is a male sterile, high yielding non-toxic accession and a line exhibiting natural polyploidy.

Currently we have approximately 50 intra and interspecific hybrids growing and we expect some of them to set flowers within the next few weeks. With the resulting BC1F1 and F2 generations we will soon enter the core breeding phase.

Over the coming 6 months we will initiate some systematic feed trials with the first generation non-toxic material we have planted at our farm. For this purpose we have established a small poultry test farm comprising of chicken, guinea fowls and turkeys.
