SGB global field trials reveal rust-resistant Jatropha curcas

June 18, 2013 |

In California, SGB has identified fungal rust-resistant hybrids of Jatropha curcas through its global network of field trials. Identification of the trait provides a critical defensive attribute to ensure plant health and yield preservation for the non-food energy crop. At multiple JMax Knowledge Center trial sites, several of SGB’s high yielding hybrids manifest a range of resistance levels to the fungal rust pathogen (Phakopsora arthuriana) – from complete immunity to moderate resistance. Rust-related diseases can be destructive not only to Jatropha, but to mainstream crops as well. The UN Food and Agriculture Organization (FAO) estimates that 29 countries in Africa, Asia and Southeast Asia — accounting for 37 percent of global wheat production — are currently affected or at potential risk from a particularly potent form of wheat stem rust called Ug99 (Puccinia graminis f. sp. Tritici). Asian soybean rust (Phakopsora pachyrhizi) increased 84% in Brazil this past cropping season compared to the previous year, according to the Embrapa Consortium of Anti-rust. Furthermore, the International Coffee Organization has called the current rust outbreak in Central America the worst since 1976.
