62 representative taro germplasm resources of different types preserved in National Aquatic Vegetable Germplasm Repository(Wuhan)were selected to identify and evaluate its main agricultural and qualitative traits.It showed that plant height,growth period,single cormel weight,dry matter content and starch content of taro with numerous cormels(white bud)were lower than those of taro with numerous cormels(red bud).But leaf area,tiller number,corm weight,cormel weight,total corm and cormel weight,commodity cormel weight and cormel number of taro with numerous cormels(white bud)were higher than those of taro with numerous cormels(red bud).Growth period was significantly positively correlated with plant height,corm weight and single cormel weight,significantly negatively correlated with tiller number significantly positively correlated with leaf area,dry matter content,starch content,significantly negatively correlated with cormel number.The correlation between any two traits of plant height,leaf area,cormel weight,total corm and cormel weight and commodity cormel weight was significantly positive.Dry matter content and starch content were significantly negatively correlated with cormel weight,total corm and cormel weight,commodity cormel weight,negatively correlated with single cormel weight.Based on the analysis results,10 excellent germplasm resources were screened,including 3 specific germplasm resources.
