Perennial rice different distantly related perennials in the hopes that at least one of these strategies would enable genes from the perennial to be moved to the cultivated rice gene pool. Hu Fengyi, now deputy director of the Food Crops Institute at YAAS, worked on the IRRI perennial-rice project and was senior author of the paper that first reported on mapping of genes for rhizome production in rice. Using the F2 population derived from the Oryza sativa/O. longistaminata cross, two dominant-complimentary genes, rhz2 and rhz3 controlling rhizomatousness were mapped. These were found to correspond with two QTLs associated with rhizomatousness in the
Mythimna separata light dorsal stripe, with black-brown lateral stripe along spiracle line. spiracles brown with black rim. Pupae are yellowish brown and shiny. The moth flies from January to April depending on the location. The larvae feed on a range of agricultural plants like "Zea mays", "Sorghum bicolor" and "Oryza sativa" and are thus considered a pest. Caterpillars do not feed on "Momordica charantia" due to the presence of the triterpenoid glucoside called momordicine II, which is a natural inhibitor of caterpillar actions. China experiences periodic outbreaks of northern armyworm infestation. The outbreak in 2012 was particularly severe. Larva can be hand
