摘要：

为了明确上海地区杂草稻形态学和农艺形状的多样性，为杂草稻的田间识别和利用提供理论支持，采用杂草稻田间育苗移栽方法，对杂草稻形态学和农艺性状进行观察，明确上海地区杂草稻形态学和农艺性状多样性。结果表明，上海地区杂草稻形态学和农艺性状多样性较丰富，变异程度较大。上海地区杂草稻主要以籼型和偏籼型为主。通过聚类分析可将36份杂草稻样本主要分为3类。主成分分析结果表明，上海地区杂草稻穗形因子、生育期因子、株型因子、粒型因子、分蘖角因子、结实率因子6个指标累计贡献率达到了85%以上。

Abstract:

It was carried out the research on morphology and agronomic traits diversity of transplanting weedy rice in Shanghai, in order to provide theoretical support to field identification and utilization. The results showed that, the diversity was abundant and variant degree was greater. Weedy rice types were indica type and partial indica type mostly. Thirty-six materials could be classified into three clusters by cluster analysis. The cumulative contribution of panicle type factor, growth period factor, plant type factor, grain type factor, tiller angle factor and seed setting rate factor comes up to 85% by main factor analysis.
