近年来,生物统计学在作物育种工作的许多方面,得到广泛应用。这对于揭示作物本身内在的规律,对于育种工作的科学化和效率化,都做出很大贡献。 但是,任何事物,都有其相反的一面。生物统计学的应用亦莫能例外。例如,我们通过对作物性状相关性的分析,可以找出一系列相关性显著或极显著性状,作为选配组合、进行杂种后代选择等的依据。还可以通过杂种后代性状与产量相关性的分析,找出选择有效的性状,提高育种工作的准确性和效率。这无疑对育种工作是有益的。但如果 In recent years, biometrics has been widely used in many aspects of crop breeding. This is to reveal the inherent laws of the crop itself, for the scientific and efficient breeding work, have made great contributions. However, everything has its opposite. Biostatistics are no exceptions. For example, by analyzing the correlations of crop traits, we can find out a series of significant or highly significant traits related to selection of hybrid offspring as an option. Through the analysis of the correlation between traits and yield of hybrid progeny, we can find out the effective traits of selection and improve the accuracy and efficiency of breeding work. This undoubtedly is good for breeding work. but if
