【摘要】 在不同花生品种之间,烂果率存在着明显的遗传差异。试验表明烂果率的高低与杂种的亲本密切相关。如果双亲均为易烂果品种,则杂种F₁也易烂果。如果双亲之中有一个亲本为易烂果品种,另一方为抗烂果品种,则杂种的烂果率一般介于双亲之间。烂果率的遗传力不高（变动于0.1531到0.4177之间）,这表明烂果率是一种数量性状,可能受控于微效基因。更多还原

【Abstract】 The peanut rotting-pod rate in different cultivars has evident genetic variation .The result of this experiment showed that the rotting-pod rate of F1 was closely related to parents.If both parents were susceptable to the disease, the hybrid F1 was also susceptable.If one parent was susceptable and the other resistant, the rotting rate of hybrid F1 would show in the middle of parents.The heritability ( h2 ) of resistance to rotting pod was low (range from 0.1531 to 0.4177), which revealed that rotting resistance was a quantitatively related to polygenes.更多还原
