| 摘 要： | 利用超薄平板微型聚丙烯酰胺凝胶等电聚焦电泳技术,对286份梨材料进行了等位酶遗传变异分析.在8个酶系中共检测到19个清晰位点和82个等位基因,19个位点均为多态位点,位点最大等位基因数为6,体现出梨属植物丰富的遗传多样性;不同居群具有特有等位基因;通过82个等位基因可以将286份材料完全区分开,表明等位酶基因型指纹可用作梨品种区分与鉴定的依据.

| Abstract: | Allozymic variation of 286 pear materials were investigated using vertical slab polyacrylamide gel electrophoresis.82 alleles of 19 loci in 8 enzyme systems were detected.All loci are polymorphic.The maximum number of alleles in a locus is 6.The result demonstrated a rich genetic diversity in pear germplasm.some specific alleles were detected in different population.Based on multi-locos genotype fingerprinting cultivars with82 alleles, 286 pear materials were clear identified, suggesting allozyme is a useful marker for peach cultivars identification. |
