六十年代以来我国已育成大批高产早籼品种,品种间的株型结构存在较大的差异。明确其株型结构类型,对进一步开展株型育种具有现实意义。1986年我们收集了一些早籼品种,并采用数值方法对其进行株型结构分析。材料和方法由中国水稻研究所提供的浙江省历年引种或育成的早籼品种93个,种植在浙江农业大学实验农场。其中农家品种9个,历年来育成并推广的矮秆高产品种49个,近年新育成的品种35个。随机区组设计,

Since the 1960s, a large number of high-yielding early indica varieties have been bred in China. There is a big difference in the plant type structure among varieties. Clearly the type of plant structure, to further carry out plant type breeding has practical significance. In 1986, we collected some indica varieties and used numerical methods to analyze them. Materials and Methods 93 early indica cultivars introduced or bred in Zhejiang Province were provided by China National Rice Research Institute and planted in experimental farm of Zhejiang Agricultural University. Among them, there are 9 farmer varieties, 49 dwarf high-yielding varieties bred and popularized over the years and 35 newly-bred varieties in recent years. Randomized block design,
