Test Data Intuitive Analysis On Hybridized Rape Quality.

This paper conducted an intuitive analysis on rape quality test data. The following results were obtained:1. The standard error was estimated using the range R = xmax ?xmin of the samples x1, x2,…, xn .2. The mean x i and the range Ri of glucosinolate content for each breed planted in different regions were gained. The mean x and R of x i and Ri divided the plane xi ? Riinto four regions. All the breeds were divided into such four categories as universal adaptation, specific adaptation etc. If x i was close to x and Ri to R , this breed belonged to adaptation.3. In regional test, the stability of each glucosinolate content was analyzed:(1) The stability was analyzed bases on the sequence of variation coefficient (CVi) of every component, and the less of the CVi , the more steady of the component.(2) The importance of glucosinolate component content related to total content was described using totalcontentxi= component contentxi. The importance of every component variation related to total content was described using totalcontenty i= conponentcontentrangeRi. The plane x i ? yi was divided into four regions:x i?< x ,yi< y ;x i?> x ,yi< y ;x i?< x ,yi> y ; x i?> x ,yi> y . using the mean x and y of x i and yi. If one glucosinolate component content was in the region xi > x, y i>y, the glucosinolate content variation was controlled by the variation of this component.
