利用双亲的信息有效地预测杂交后代性状分布,对提高育种效率有着积极的作用。本文借助于有效因子的概念建立了水稻主要性状 F_2代分布模型。通过一系列试验数据估计出模型的参数。然后,应用这些模型对另一些杂交组合进行预测。经过与实测结果的比较,可以看出预测的准确性是令人满意的,说明本文所述方法是有效及可行的。 Using parents’ information to predict the distribution of traits in hybrid progenies effectively has a positive effect on improving the breeding efficiency. In this paper, the concept of effective factor was used to establish F_2 generation distribution model of rice main characters. Through a series of experimental data to estimate the model parameters. These models are then used to predict other hybrid combinations. After comparison with the measured results, it can be seen that the accuracy of the prediction is satisfactory, indicating that the method described herein is effective and feasible.
