运用函数图形计算烟草种质资源的抗病性

Calculating Disease Resistance of Tobacco Germplasm Resources Using Function Graphics

摘要: 摘要：以目前通用的烟草抗病性指数鉴定方法为基础，通过建立一个新的方程，运用函数图形，鉴定烟草种质资源的抗病性强弱，并与国内通用的抗病性鉴定方法进行比较。结果表明，两种方法具有一定的相似性和部分差异性。该方法可供病害专家和烟草育种专家参考。

Abstract: Abstract: Based on common used index approach of tobacco disease resistance, we established a new function and applied function graphics to evaluate the disease resistance of the tobacco germplasm resources. The result showed that there were both similarity and difference between the common approach and the new approach. The new approach can be used as a reference by experts of tobacco breeding and pathology.
