Amphidiploid - Encyclopedia.com
2018年5月17日 · amphidiploid Describing an organism, cell, or nucleus that contains diploid sets of chromosomes originating from two different species. Crosses between taxonomically unrelated organisms are usually infertile, principally because the chromosomes lack a partner with which to pair during meiosis.

Amphiploidy - an overview | ScienceDirect Topics
Areas of overlap or points of contact between two populations that are distinguishable based on one or more heritable characters where viable or partially fertile hybrids are formed. Permanent transfer of genes from one or more species, subspecies, or race into another species, subspecies, or race via hybridization and back-crossing.
Generation of amphidiploids from hybrids of wheat and related …
The present study describes the development of F1 hybrids between wheat and related species from the genera Aegilops, Secale, Thinopyrum, and Triticum and production of new amphidiploids. Amphidiploid lines were produced from 20 different distant relatives. Both colchicine and caffeine were successfully used to double the chromosome numbers.

2017年4月19日 · This amphidiploid can be crossed with cultivated peanut (AABB) to provide genes of interest to the cultivar. In this study, the sterile diploid hybrids from A. magna V 13751 and A. kempff-mercadoi V 13250 were treated with colchicine for polyploidization, and the amphidiploids were crossed with A.
