Comparisons and Correlation Analysis of Different Identifying Methods for Grape Cultivars Resistance to Plasmopara viticola
摘要
Abstract
[Objective]Selecting suitable inoculation method is one of the most important factors to determine whether the identification of cultivar resistance to disease is successful or not and whether the result of identification is reliable. Comparison and correlation analysis of different indentifying methods for grape cultivars resistance to Plasmopara viticola were conducted in this paper to look for a simple and fast identifying method, and to lay foundation for identification of cultivar resistance to disease and pathogenic differentiation. [Method] The results from identification of 15 different resistance grape cultivars to Plasmopara viticola by indoor identification of leaves, field identification by leaf inoculation and identification by natural infection were analyzed by correlation analysis with DPS, and the feasibilities of three identification methods were compared. [Result]The results showed that the three methods were consistent and the correlation coefficients were above 0.95; high resistance, resistance, susceptible and high susceptible cultivars were preliminary screened from 15 cultivars, which laid the foundation for identification of cultivar resistance to disease and pathogenic differentiation. [Conclusion] Inoculating leaf tissues indoors was an effective method for grape cultivars resistance to PlasTnopara viticola because it was simple, fast, reliable and easy to control.关键词
