【摘要】 偏分离是遗传作图中的普遍现象,是一种强有力的进化动力。在植物方面,标记偏分离的比例、程度、来源、遗传效应等因物种、群体类型、杂交组合、标记类型等的不同而有很大变化。从偏分离的表现和共同特征、偏分离产生的原因、偏分离基因位点的标记定位、偏分离对遗传作图的影响及克服方法等方面,对植物(主要是作物)中的偏分离研究进展进行了综合分析。更多还原

【Abstract】 Segregation distortion, which is identified as a strong evolutionary force, is common in genetic mapping. In plants, the percentage, degree, origin and genetic effects of segregation distortion vary significantly with species, population types, crosses and marker types. The exhibition and common features, causes, methods of mapping segregation distortion loci, effects of segregation distortion on map construction and corresponding mapping strategies in plants, mainly in crops, are reviewed.更多还原
