polyploid
polyploid, a. (n.) Biol. (ˈpɒlɪplɔɪd) [a. G. polyploid (H. Winkler 1916, in Zeitschr. f. Bot. VIII. 422): see poly- and -ploid.] Having more than two homologous sets of chromosomes (in each cell nucleus). Also as n., a polyploid organism.1920 W. E.

Polyploid complex
A polyploid complex, also called a diploid-polyploid complex, is a group of interrelated and interbreeding species that also have differing levels of ploidy In many diploid-polyploid complexes the polyploid hybrid members reproduce asexually while diploids reproduce sexually. wikipedia.org

The transcriptional landscape of polyploid wheat | Science
Polyploidy arises from whole-genome duplication or interspecific hybridization and is ubiquitous in eukaryotic plant and fungal lineages. Polyploidy has been proposed to confer adaptive plasticity, thereby shaping the evolution of plants, fungi, and, to a lesser degree, animals ( 1, 2 ).

Crepis
Polyploid individuals may still be able to carry out sexual reproduction and therefore produce sexual offspring, allowing for the formation of new polyploid When pollen from a polyploid individual fertilizes diploid flowers, the resultant seeds are typically polyploid, which lowers the diploid population over wikipedia.org

Why do plants produce so many hybrids as a kingdom? Why do plants produce so many hybrids? I have read that they are the largest kingdom of organisms to do so. Does this have something to do with polyploidy events?
Specifically if you look at the grasses, most grasses that are diploid (eg., AA, BB), cannot hybridize, but in some rare events when they form polyploid

Reciprocal silencing
When a polyploid species arises, its genome contains homoeologs, duplicated chromosomes with equivalent genetic information. Reciprocal silencing on the population level has been proposed as a means of allopatric speciation following a polyploid event. wikipedia.org

染色体倍性
有些常见生物就是多倍体（polyploid），譬如金鱼、鲑鱼、蚂蟥、扁形虫、有尾目和蕨类植物。多套的动物通常都是低等动物，或能行孤雌生殖的居多。 这种多倍体，又分异源多倍体（Allopolyploidy）和同源多倍体（Polyploid或Autopolyploidy，或「单源多倍体」），特别是前者的染色体来自不同种。 在双套生物中，有一个过程，将双倍体的细胞分裂成单倍体，使配子结合后的合子为双倍体，称为减数分裂。 wikipedia.org

更大的山药从哪里来？ 追踪多倍体植物"美味"传播历史的全球努力
山药是通过栽培 克隆繁殖 大多数新品种是组织培养产生的体细胞克隆。 确定山药驯化中心和多样化的基因库对于在未来寻找更具弹性和更高产的品种非常必要。 1886年， 德坎多勒 首先提出山药起源于印度-马来亚地区，多年来甚至今天，山药的驯化问题仍未解决。
