Maypan Coconut Palm

	Maypan Coconut Palm Maypan is an F1 hybrid coconut palm that was developed by the Research Department of the Coconut Industry Board of Jamaica to be resistant to Lethal Yellowing disease. It was created experimentally in 1962 by cross pollinating two varieties of ''Cocos nucifera'' and, after extensive disease exposure and yield performance trials, was named and released in 1974 when a suitable method of mass controlled pollination had been devised.

	F1 Hybrid An F1 hybrid (also known as filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. F1 hybrids are used in genetics, and in selective breeding, where the term F1 crossbreed may be used. The term is sometimes written with a subscript, as F hybrid. Subsequent generations are called F, F, etc. The offspring of distinctly different parental types produce a new, uniform phenotype with a combination of characteristics from the parents. In fish breeding, those parents frequently are two closely related fish species, while in plant and animal breeding, the parents often are two inbred lines. Gregor Mendel focused on patterns of inheritance and the genetic basis for variation. In his cross-pollination experiments involving two true-breeding, or homozygous, parents, Mendel found that the resulting F1 generation was heterozygous and consistent. The offspring showed a combination of the phenotypes from each parent that were genetically dominant. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Coconut The coconut tree (''Cocos nucifera'') is a member of the palm tree family ( Arecaceae) and the only living species of the genus ''Cocos''. The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a nut. The name comes from the old Portuguese word '' coco'', meaning "head" or "skull", after the three indentations on the coconut shell that resemble facial features. They are ubiquitous in coastal tropical regions and are a cultural icon of the tropics. The coconut tree provides food, fuel, cosmetics, folk medicine and building materials, among many other uses. The inner flesh of the mature seed, as well as the coconut milk extracted from it, form a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of clear liquid, called ''coconut water'' or ''coconut juice''. Mature, ripe coconut ...

picture info	Palm Tree The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Lethal Yellowing Lethal yellowing (LY) is a phytoplasma disease that attacks many species of palms, including some commercially important species such as the coconut and date palm. In the Caribbean it is spread by the planthopper ''Haplaxius crudus'' (former name ''Myndus crudus'') which is native to Florida, parts of the Caribbean, parts of Australia and Central America. The only effective cure is prevention, i.e. planting resistant varieties of coconut palm and preventing a park-like or golf-course-like environment which attracts the planthopper. Some cultivars, such as the Jamaica Tall coconut cultivar, nearly died out because of lethal yellowing. Heavy turf grasses and similar green ground cover attracts the planthopper to lay its eggs there, and the nymphs develop at the roots of these grasses. The planthoppers' eggs and nymphs can pose a great threat to coconut-growing countries' economies, especially ones into which grass seeds for golf courses and lawns are imported from the Americas.

	Malayan Dwarf Dwarf coconut is a range of varieties of coconut palm. The use of the word “dwarf” here does not refer to the tree's size, as it can reach heights of 50–100 feet which is certainly not a dwarf. Instead, the dwarf designation refers to the size in which it will begin to produce the coveted or harvestable coconut. Dwarf varieties Other types of dwarfs are: (in alphabetical order) Cameroon Red Dwarf Chowghat Dwarf Green Chowghat Dwarf Orange Coconino Eburnea Equatorial Guinea Green Dwarf Equatorial Guinea Yellow Dwarf Fiji Dwarf: form a large bulb at the lower stem Gangabondam Ghana Yellow Dwarf Gon Thembili Haari Papua Kelapa Gading Kelapa Radja Laccadive Dwarf Lakshadweep Dwarf Maldive Dwarf Mangipod Mu-see-Keo N'uleka Nok-koom Pilipog Pugai Pumila Rath Thembli Regia Malayan Dwarf The ''Malayan Dwarf'' is a variety of dwarf coconut. The palm is classified based on the nut color: ivory yellow nuts, apricot red nuts, and green nuts. The palm's resistanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Pollen Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Panama Tall Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of E ...
