Oryza glaberrima deep water, and makes it easier to harvest. African rice tends to elongate rapidly if completely submerged, which is not advantageous in regions prone to short floods, as it weakens the plant. The grains of African rice are more brittle than those of Asian rice. The grains are more likely to break during industrial polishing. Broken rice is widely used in West Africa, and some cookbooks from the region will suggest manually breaking the grains for certain recipes,(example) but most broken rice eaten is from Asian rice, about 16% of which is broken in processing. The genome of "O. glaberrima"
Scirpophaga nivella orange anal tuft, sometimes brownish in the female. The larvae are off white with a reddish dorsal line. Major feeding plant is sugarcane, besides "Oryza sativa", "Scirpus", "Cyperus", "Eleocharis" (including "Eleocharis dulcis") and "Calidum articulatum" are also susceptible as feeding plants of the moth. Caterpillars bore into midrib, by leaving red markings and small holes on the leaves. Then it bore in the upper portion of stem, causing "dead heart" symptoms. Gradually, side branches start growing from a lower node, giving a characteristic "bunchy top" appearance to the plant. Most effective method is using biological predators and parasitoids. It is
