Oryza glaberrima has been sequenced, and was published in 2014. This allowed genomic as well as physiological comparison with related species, and identified some effects of some genes. African and Asian rice do not readily interpollinate, even under controlled conditions, and when they do, the offspring are very rarely fertile. Even the fertile crossbred offspring have low fertility. Crossbreeding seems to have succeeded in at least one area of Maritime Guinea, as some varieties there show crossbred genes. More recently, the nerica cultivars (new rice for Africa) have been developed using green revolution techniques like embryo rescue. Over 3000 crosses were made
Saluria inficita the plants show dried up shoots and turn yellow. Damage can controlled by hand picking, pheromone usage, light traps and usage of chemical insecticides such as carabaryl, methyl parathion, phosphomidon or dimethoate. Saluria inficita Saluria inficita, the white stem borer, is a moth of the family Pyralidae. The species was first described by Francis Walker in 1863. It is found in India and Sri Lanka. Its caterpillars are pests of "Eleusine coracana", "Oryza sativa", "Setaria italica" and "Zea mays". The adult has brownish wings. A pale white band runs along the margin of forewings. Hindwings white. The caterpillar is whitish
