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.
