摘 要 ：韭(Allium tuberosum Rottl. ex Spreng.)原产我国,由于抗逆性强,栽培容易,又具有特异的辛香气味,自古以来就是群众喜爱的蔬菜品种之一。据文献记载,栽培的韭有二倍体和四倍体两类,分别由野生的二倍体韭和四倍体韭经长期驯化而来。栽培的四倍体韭产量比二倍体高。目前各地的商品韭多为四倍体,二倍体已不多见,而三倍体韭迄今未见报道。
Abstract:It was a fine variety of fragrant-flowered garlic(Allium tuberosum Rottl. ex Spreng.)that was discovered in the western of Yunnan Province in 1982. It grows vigorously but does not bear fruit. It can be propagated asexually only by bulb. Its karyotype was studied The chromosome number in its somatic cells is 2n=24, which contains three complete sets of chromosomes and is a triploid. The karyotype is 2n = 3x = 24 = 21m +3st. The genome constitution of the triploid is very similar to that of widely cultivated tetraploid. As the triploid variety is of some superior qualities, it is propagated vegetatively by local peasants.
