甜菜多倍体品种是用人工诱变的方法,将普通二倍体糖用甜菜细胞核中的染色体(n=18)加倍而变成四倍体(n=36),然后再用四倍体和二倍体甜菜杂交制成三倍体杂种(n=27)直接用于生产。四倍体和三倍体甜菜通称为“多倍体”甜菜,其特点是产量显著优于双亲,含糖分接近或高于两亲本,并且有抗逆性强,纯度高,灰分低,杂质少,易结晶等优点,目前西欧各国采用多倍体品种,其单位面积产量和产糖量都显著上升。 The beet polyploid variety is a method of artificial mutagenesis, doubling the chromosome of common diploid sugar (n = 18) in the nucleus of beet to become tetraploid (n = 36), and then using tetraploid and Diploid beet hybrids made of triploid hybrids (n = 27) were used directly in the production. Tetraploid and triploid beet Commonly known as “polyploid” beets, which are characterized by significantly better yields than their parents, sugar content close to or above the amphipathic, and have strong resistance, high purity, low ash, low levels of impurities , Easy to crystallize, etc. At present, polyploid varieties are used in all countries in Western Europe, and the yield per unit area and the amount of sugar produced have both risen significantly.
