1 beet varieties often determines the stability of the promotional value of the varieties and production efficiency. And foster stable traits, varieties with high yield and quality level is the relentless pursuit of the goal of breeding work. Sugar beet growing areas span, terroir and ecological conditions vary widely. Kinds of units to be selected according to the ecological conditions of the region the beet varieties suitable for cultivation in the region in order to achieve the maximum economic benefit. Objective, comprehensive, just and comprehensive assessment of beet varieties stability is essential. This study aimed at the application of an integrated approach to determine the stability of the sugar beet varieties, studies have shown that this method can be objective, comprehensive, integrated assessment of the stability of the sugar beet varieties. First proposed the concept of stability of varieties. Stability refers to artificially regulate a variety of phenotypic state (including changing the composition and the frequency of the genotype groups) or in changes in the environment, maintain their phenotype (including genotype maintain the original composition and the frequency), its yield and some economic traits in different regions and different years to adapt to changes in the environment, the ability to maintain a relatively stable. The stability of the species is divided into static and dynamic stability. Followed by a full stable mechanism: Variety Stability is essentially a buffer species to environmental change. A variety of stability there are two obvious ways, individual buffer and groups buffer. Third varieties stability measurement methods: 1, according to varieties, the average yield and the size of the phenotypic variation coefficient of the grouping of varieties; 2, according to the environmental variance Law, the stability of the reactive species of environmental variance method is static stability; according to the size of the genotype environment interaction. (1) ecological effects; the ② stability variance. 4, according to the linear regression of the performance of the genotype and the environment stability parameters. Of ① Fnlay and wilkinson law. The ② Eberllart-Russell method. 5, the coefficient of determination r to law. 6, nonparametric stability analysis-Hulhn the Nallar law. In this paper, DPS data processing system tested eight varieties around the point of production, sugar content, sugar-producing amount of processing. Comprehensive Assessment results show that: from the production point of view, A, G, D, No. varieties performed well or better. E, F, B performance in general, C, H performance is not good or better; sugar point of view: H, D No. varieties were better, B, A, F varieties good or better performance, G, E, No. performance varieties, C No. varieties poor performance; sugar yield from the point of view, No. A good performance of varieties and, G D No. varieties performed better, the general performance of B, F, E, varieties, C No. varieties performance bad , H No. varieties poor performance. Eberhart-Russell, on this basis, further evaluation. Rberhart. The principle of Rallell: According to the gene × environment interaction principle provide two parameters determination of the stability of the varieties, the reaction parameters (Paramttr.Of Res.Pnle environment). Its estimated value regression coefficient B_j; offline regression variance S to 2d_j called the stability parameter. (Parameiterof.Itability) Ebtrhart-Rulltll interpretation of the two parameters called Jilin Agricultural University Thesis beet varieties grid qualitative analysis when h years old knife that stability varieties, so the long difference () was not significant, ie varieties ring. Habitat reaction linear relationship established in this context, where Bu large, L changes by one unit then Y changes increase accordingly, _ and thus should be planted in a highly suitable environment to its full production potential, where Bu smaller > 1. Varieties shown little response to the environment, there is a wide range of adaptability. Bu is negative, the varieties of small mouth with a wide range of responses to the environment adaptability. B is negative, the varieties can be adapted to a poor environment. Thus, when the S \\ L; 0 and the difference was not significant, b predict the performance of the varieties, Where in this case) varieties oh pre-side performance. . Species, known as the stability of varieties, and thus stability forecast meaning. Other hand, if S \\ l; significant difference () \regression coefficients Bu deviation before.!; cloud first test sound economic traits, yield, sugar content and sugar-producing amount of analysis of variance, and seek the points mean square error, mean square error from points count _ the average error mean square mean square as a merger, production S \\ 271) l the sugary S - called sugar yield S * () suddenly called J contingent _ # leisure points yield, sugar content and production Boring the amount of average variance analysis results showed that the varieties X environment mean square for the F test should be MSC = S at first glance even as the denominator: l, l given the results of varieties x regions significantly Bodhisattva, should be further for stable parameter estimation. otherwise meaningless and h and the pair I; First calculate the production environment including the boring rates and sugar yield index mouth again + splash environmental index obtained regression coefficients and regression sum of squares and then come to the d spoon;, according to the results of the two parameters and points ---- analysis point of view, from a production point of view, all varieties S \\ fly () difference was potato, indicating that the relationship between the genotype and the environment is unstable to non-_ linear relationship butterfly and death from the point of view of all varieties regression mean square was not significant Lu, and the value is very small, 8P varieties established the linear relationship of the Environmental Response, man, 11, D number is the stability of species with a wide range of adaptation r +, C, E, G, No. varieties not suitable for production on the application. H No. varieties should be planted in a highly suitable environment - 0 stars from sugar yield analysis results, D, G, H No. varieties S tea spoon significant difference 0, indicating genotype work environment relationship exists between non - linear relationship will not be discussed. A, B, C, E, F, No. varieties S and 0 the difference was not statistically Department. varieties on the environment anti __. should be a linear relationship was established, in this context, A variety b; -0 9515, and the average number of high, indicating the product _ good stability, wide adaptability, B, C, E, F, No. varieties and death mean performance in general, not suitable for the production , -. together A variety stability varieties with a wide range of adaptability, and the actual kiss. \
