Penglai Rice
Penglai rice ( zh, 蓬萊米, ), also called Ponglai or Hōrai rice, is the most popular List of rice cultivars, rice cultivar in Taiwan. It accounts for over 90% of local rice production, far more than the two other major types of rice planted and consumed in Taiwan, zailai rice and glutinous rice. Penglai rice is a Hybrid (biology), hybrid produced by crossbreeding between strains of the subspecies ''Oryza sativa'' subsp. ''japonica'' (japonica rice). It was initially developed by the Japanese when Taiwan was Taiwan under Japanese rule, under Japanese colonial rule because the colonizers preferred the taste of their home-grown japonica rice. But japonica rice's sensitivity to day-length did not allow it to grow well in Taiwan's long hours of sunlight and subtropical climate. In 1921, Japanese researchers , known as "father of penglai rice", and his colleague Megumu Suenaga (末永仁), known as "mother of penglai rice", began to crossbreed two strains of highland japonica rice, ...

Oryza Sativa
''Oryza sativa'', having the common name Asian cultivated rice, is the much more common of the two rice species cultivated as a cereal, the other species being ''Oryza glaberrima, O. glaberrima'', African rice. It was History of rice cultivation, first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago. ''Oryza sativa'' belongs to the genus ''Oryza'' and the BOP clade in the grass family Poaceae. With a genome consisting of 430megabase, Mbp across 12 chromosomes, it is renowned for being easy to Genetically modified rice, genetically modify and is a model organism for the study of the biology of cereals and Monocotyledon, monocots. Description ''O. sativa'' has an erect stalk stem that grows tall, with a smooth surface. The leaf is lanceolate, long, and grows from a ligule long.

List Of Rice Cultivars
This is a list of rice cultivars, also known as rice varieties. There are several species of grain called rice. Asian rice (''Oryza sativa)'' is most widely known and most widely grown, with two major subspecies (''indica'' and ''japonica'') and over 40,000 varieties. Also included in this list are varieties of African rice (''Oryza glaberrima'') and wild rice (genus ''Zizania''). Rice may vary in genetics, grain length, color, thickness, stickiness, aroma, growing method, and other characteristics, leading to many cultivars. For instance, over nine major rice cultivars exist to make sake alone. The two subspecies of Asian rice, indica and japonica, can generally be distinguished by length and stickiness. Indica rice is long-grained and unsticky, while japonica is short-grained and glutinous. Rice can also be divided based on processing type into the two broad categories of brown and white. Brown rice is whole grain, with only the inedible hull of the seed removed, while wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zailai Rice
Zailai rice () is a cultivar of rice derived from the subspecies ''Oryza sativa'' subsp. ''indica'', or indica rice, traditionally grown in Taiwan. It is one of three major types of rice planted and consumed in Taiwan, the other two being penglai rice and glutinous rice. The name "zailai" is derived from the Japanese "ざいらい" meaning "existing", to distinguish it from the penglai rice hybrids developed by the colonizers when Taiwan was under Japanese colonial rule. Zailai rice cultivars can be sub-divided into soft (''e.g.'' "Taichung Sen No. 10") and hard (''e.g.'' "Taichung Sen No. 17") indica rice varieties. Zailai rice cultivation in Taiwan began in the 17th century during the Dutch Formosa period, when the Dutch introduced indica rice and water buffalo to the island; the Hokkien immigrants from the Fujian area in China also imported different strains of indica rice. Subsequently, zailai rice was planted around the island by military settlements of the Kingdom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glutinous Rice
Domestication syndrome refers to two sets of phenotypic traits that are common to either domesticated plants or domesticated animals. Domesticated animals tend to be smaller and less aggressive than their wild counterparts; they may also have floppy ears, variations to coat color, a smaller brain, and a shorter muzzle. Other traits may include changes in the endocrine system and an extended breeding cycle. These animal traits have been claimed to emerge across the different species in response to selection for tameness, which was purportedly demonstrated in a famous Russian fox breeding experiment, though this claim has been disputed. Other research suggested that pleiotropic change in neural crest cell regulating genes was the common cause of shared traits seen in many domesticated animal species. However, several recent publications have either questioned this neural crest cell explanation or cast doubt on the existence of domestication syndrome itself. One recent publica ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Crossbreeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding. In animal breeding, ''crossbreeds'' are crosses within a single species, while '' hybrids'' are crosses between different species. In plant breeding terminology, the term ''crossbreed'' is uncommon, and no universal term is used to distinguish hybridization or crossing within a population from those between populations, or even those between species. Crossbreeding is the process of breeding such an organism. It can be beneficially used to maintain health and viability of organisms. However, irresponsible crossbre ...

Japonica Rice
Japonica rice (''Oryza sativa'' subsp. ''japonica''), sometimes called sinica rice, is one of the two major domestic types of Asian rice varieties. Japonica rice is extensively cultivated and consumed in East Asia and Italy, whereas in most other regions indica rice is the dominant type of rice. Japonica rice originated from Central China, where it was first domesticated along the Yangtze River basin approximately 9,500 to 6,000 years ago. Classification The subspecies ''japonica'' can be classified into three subgroups, 'temperate japonica', 'tropical japonica' (obsolete designations: 'javanica'; ), and 'aromatic'. Temperate japonica is cultivated in East Asia (China, Japan, Korea, and Vietnam), while tropical japonica is in Indonesia, Madagascar, and also the Americas where it was brought to with slave trade.

Taiwan Under Japanese Rule
The Geography of Taiwan, island of Taiwan, together with the Penghu, Penghu Islands, became an annexed territory of the Empire of Japan in 1895, when the Qing dynasty ceded Taiwan Province, Fujian-Taiwan Province in the Treaty of Shimonoseki after the Japanese victory in the First Sino-Japanese War. The consequent Republic of Formosa resistance movement on Taiwan was Japanese invasion of Taiwan (1895), defeated by Japan with the Capitulation of Tainan (1895), capitulation of Tainan. Japan ruled Taiwan for 50 years. Its capital was located in Taipei, Taihoku (Taipei), the seat of the Governor-General of Taiwan. Taiwan was Japan's first colony and can be viewed as the first step in implementing their "Nanshin-ron, Southern Expansion Doctrine" of the late 19th century. Japanese intentions were to turn Taiwan into a showpiece "model colony" with much effort made to improve the island's economy, public works, Industrial sector, industry, cultural Japanization (1937 to 1945), and sup ...

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication ( translesion synthesis). Mutations may also result from substitution, insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics ( phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutati ...

Mount Penglai
Penglai ( zh, t=蓬萊仙島, l=Penglai Immortal Island) is a legendary land of Chinese mythology. It is known in Japanese mythology as Hōrai and Bồng Lai in Vietnam. McCullough, Helen. ''Classical Japanese Prose'', p. 570. Stanford Univ. Press, 1990. . Location According to the '' Classic of Mountains and Seas'', the mountain is located at the eastern end of Bohai Sea. According to the pre-Qin mythology which retells the legend of Xu Fu presenting a memorial to the Qin Emperor in order to seek for the elixir of life, there are three godly mountains which are found in the Bohai sea where immortals reside. These mountains are Penglai, Fāngzhàng (), and Yíngzhōu (/). Other islands where immortals reside are called Dàiyú () and Yuánjiāo (). In the ''Illustrated Account of the Embassy to Goryeo in the Xuanhe Era'' (; ''Xuanhe fengshi Gaoli tujing''), written in 1124 by Xu Jing (), Mount Penglai is located on an inhabited island which is found within the boundaries of ...
