Non-Toxic Elite Seeds
JATROPOWER key focus area: non-toxic Jatropha for biofuel and animal feed ingredient as by-product
JATROPOWER is committed to the delivery of quality non-toxic Jatropha seedlings from selected elite accessions and continuous technical support for its cultivation, harvesting and seed processing to customers. From the base of over 20 non-toxic accessions, elite cultivars have been selected and are being improved genetically by a marker assisted crossing program.
First results of our hybridisation and improvement programme of the best toxic and non-toxic plants seem not only to promise that a similar non-toxic yield can be achieved as with the best toxic hybrids, which has been shown to be much superior than that of average natural plants. Read More
Also very interesting is the inheritance pattern of the non-toxic trait, which we have shown to follow the Mendelian pattern of inheritance. The dominance of the toxic character results in the cross pollinated seeds of the non-toxic plants (which are themselves always non-toxic) likely producing daughter plants that could produce toxic seeds. This provides natural protection for the producer of non-toxic Jatropha seed material from unauthorised multiplication through seeds generated from a plantation.
Apomixis is a character in Jatropha that could result in easier generation of clones from desired plants. Jatropower has identified certain leads towards using this character to enable easier generation of clones of the desirable hybrids.
JATROPOWER’s non-toxic elite seeds are commercially available since 2015.
A publication that came out of our research on variation in Jatropha accessions and markers for early identification of the non-toxic character of Jatropha that can assist in its accelerated genetic improvement can be seen at http://www.sciencedirect.com/science/article/pii/S0168945213000447
