摘要
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。
varieties of buckwheat representing various variety ecotypes have been classified into 4 groups and 12 types by means of systematical classification method.The 4 group are:Ⅰ high yielding,Ⅱ medium yielding,Ⅲ low yielding and Ⅳ low yielding with quite dwarf plant.The medium yielding of which has 2 subgroups,i.e.Ⅱ 1 medium to high yielding, Ⅱ 1-2 medium to low yielding. The 12 type are:Ⅰ 1 high yielding, Ⅱ 1 1 high yielding,Ⅱ 1 2 medium yielding,Ⅱ 1 3 medium yielding with high plant height and large seed,Ⅱ 2 1 high yielding,Ⅱ 2 2 medium yielding,Ⅱ 2 3 low yielding with early ripenting and large seed, Ⅱ 2 4 low yielding,Ⅲ 1 medium yielding, Ⅲ 2 low yielding with dwarf,Ⅲ 3 Zero yieding and Ⅳ 1 low yielding with quite dwarf plant.
