选择来自广东佛冈县地处山林区远离稻田的一个普通野生稻生境中的25份野生稻样本,以国外多年生、一年生普通野生稻7份样本和广东地方栽培稻8个品种为对照进行种植观察,调查了21个形态生物学性状,对调查数据作方差分析表明,有20个性状表现极显著差异,1个性状表现显著差异。通过模糊聚类分析,可将25份样本分为4类,各类与对照材料之间表现不同的遗传差异,说明该生境野生稻存在较丰富的遗传变异,但从形态生物学和生育期观察,从中尚未发现一年生型、栽培型、粳型等变异类型的分化。
Twenty-five wild rice samples from a common wild rice habitat in Fulin County, Guangdong Province, which is far away from the paddy field in Shanlin District, were planted with 8 perennials, 7 annual wild common rice varieties and 8 cultivated local rice cultivars in Guangdong , 21 morphological and biological traits were investigated. An analysis of variance on the survey data showed that there were 20 significant traits and 1 significant trait. By means of fuzzy clustering analysis, 25 samples can be divided into 4 categories, and all kinds of genetic materials showed different genetic differences, indicating that the habitat wild rice is rich in genetic variation, but from morphological and biological observation of growth period , From which we have not found any variation of the type of annual, cultivated or japonica type.
