Oryza rufipogon is a species of flowering plant in the family Poaceae. [2] [3] It is known as brownbeard rice, [4] wild rice, [5] and red rice. [5]In 1965, Oryza nivara was separated off from O. rufipogon.
Oryza coarctata is a form of wild rice that grows in saline estuaries and is harvested and eaten as a delicacy. [3] The plant is salt-tolerant, and is seen as a possibly important source of salt-tolerance genes for transfer to other rice species. [4] [5] It is closely related to Oryza australiensis. [6]
Breeding locations are often chosen for very specific requirements of shelter and proximity to food; moreover, the breeding season is a particular time window that has evolved for each species to suit species anatomical, mating-ritual, or climatic and other ecological factors. [1]
Choosing from among the possible quality goals and then achieving them is a "formidable challenge" [35] for all rice breeding programs. Low yield: the high yield of elite grain varieties is always compromised by crossing with wild material. However, even low-yielding wild rice species can harbor genes for increasing yield [36] [37]
Rice can come in many shapes, colours and sizes. This is a list of rice cultivars, also known as rice varieties.There are several species of grain called rice. [1] Asian rice (Oryza sativa) is most widely known and most widely grown, with two major subspecies (indica and japonica) and over 40,000 varieties. [2]
Wild rice, also called manoomin, mnomen, psíŋ, Canada rice, Indian rice, or water oats, is any of four species of grasses that form the genus Zizania, and the grain that can be harvested from them. The grain was historically and is still gathered and eaten in North America and, to a lesser extent, China , [ 2 ] where the plant's stem is used ...
Mares carry their young (called foals) for approximately 11 months from conception to birth. (Average range 320–370 days.) [2] Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year.
In domestic breeding, the foal and dam are usually separated from the herd for a while, but within a few weeks are typically pastured with the other horses. A foal will begin to eat hay, grass and grain alongside the mare at about 4 weeks old; by 10–12 weeks the foal requires more nutrition than the mare's milk can supply.
