Upland rice (also called dry rice) is rice grown in dry-land environments. The term describes varieties of rice developed for rain-fed or less-intensely irrigated soil instead of flooded rice paddy fields or rice grown outside of paddies.
These are the southern delta (with its Mekong Delta dominating rice coverage), the northern delta (the tropical monsoon area with cold winters) and the highlands of the north (with upland rice varieties). [3] The most prominent irrigated rice system is the Mekong Delta. [3] Rice is a staple of the national diet and is seen as a "gift from God". [4]
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]
As a plant breeder, he made significant contributions to rice breeding. He provided guidance for the development, isolation, and release of nine Seed Board rice varieties: Milpal 4, HBD-2, Azmil 26 and C-22 for upland rice production, and C-18, C4-63, C4-137, C-168 and C-12 for lowland rice production.
The broad classification of rice grown includes long-grain rice, medium-grain rice and short-grain rice. [27] While more than 100 varieties of rice are now grown in the world, in the US 20 varieties of rice are commercially produced, primarily in the states of Arkansas, Texas, Louisiana, Mississippi, Missouri, and California.

Rice production is based on its environment, resulting in rain-fed lowland rice, winter rice, deep-water rice, upland rice and irrigate rice. [4] Out of the three distinct seasons, the monsoon season is the main rice production season as rice paddies rely on copious amounts of water. [ 4 ]
38 million ha (26%) of rice lands are terraced but unirrigated. This cropping system produces about 17% of world rice. [8] While upland rice production systems were the initial target for the perennialization of rice, the perennial habit may prove to have benefits in paddy systems where erosion is less of a concern.
