采用系统聚类分析方法 ,把来源于全球的 1 2 1个荞麦品种分成了 1 2类 ,即 高产类、 1 -1中高产高产类、 1 -2中高产中产类、 1 -3中高产高秆大粒中产类、 2 -1中低产高产类、 2 -2中低产中产类、 2 -3中低产早熟大粒低产类、 2 -4中低产低产类、 -1低产中产类、 -2低产矮秆低产类、 -3低产无产类和 特矮低产类。并对各类荞麦品种的性状特征及黄土丘陵区所适宜的荞麦品种的生态性状及特性进行了论述
A total of 121 buckwheat cultivars from the world were classified into 12 high-yielding varieties by systematic clustering analysis. Among them, 1 -1 middle and high yielding middle class, 1 -2 medium high yield middle class, 1 -3 middle high yield high yield Middle and low yielding middle class, low yielding middle class and low yielding middle class, low yielding middle class and low yielding middle class, -2 middle and low yielding middle class, -2 middle and low yielding middle class and low yielding middle class, Low-yield category, -3 low yield pro-category and special low-yield category. The characteristics of buckwheat varieties and the ecological characters and characteristics of buckwheat varieties suitable for loess hilly region were also discussed
