| 摘 要： | 通过对草莓种质资源的主要数量性状进行分析研究,得出了草莓果实主要数量性状的变异情况,并且对这些数量性状进行K-S检验,对符合正态分布的数量性状统一用(X-1.2818s)、(X-0.5246s)、(X 0.5246s)和(X 1.2818s)4个点分为5级,从而使性状值落入1~5级的概率分别为10%、20%、40%、20%和10%;或用(X 0.5246s)和(X 1.2818s)2个点分为3级,性状值落入3级的概率分别为30%、40%和30%。

| Abstract: | The main quantitative characters of strawberry germplasm were studied,and the variations of main quantitative characters of strawberry fruit were gained and these main quantitative characters were analysized by K-S.The values of normally distributed characters could be divided,in a unified way,into 5 grades by dividing points:(X-1.2818s),(X-0.5246s),(X 0.5246s) and(X 1.2818s),or into 3 grades by dividing points:(X 0.5246s) and(X 1.2818s).In the former case the occurrence probability of 1-5 grade was 10 %,20 %,40 %,20 % and 10 % respectively,in the latter case,the occurrence probability of 1-3 grade is 30 %,40 % and 30 %,respectively. |
