摘要
从国家水生蔬菜种质资源圃(武汉)中选择62份有代表性的不同类型多子芋种质资源,对其主要农艺性状及品质性状进行鉴定评价和优异种质资源筛选.结果表明,白芽多子芋的株高、生育期、单个子孙芋质量、干物质含量、淀粉含量均低于红芽多子芋,而叶面积、分株数量、母芋质量、子孙芋质量、球茎总质量、商品芋质量、子孙芋数量均高于红芽多子芋.生育期与株高、母芋质量、单个子孙芋质量呈极显著正相关,与分株数量呈极显著负相关,与叶面积、干物质含量、淀粉含量呈显著正相关,与子孙芋数量呈显著负相关.株高、叶面积、子孙芋质量、球茎总质量、商品芋质量间两两呈极显著正相关.干物质含量和淀粉含量与子孙芋质量、球茎总质量、商品芋质量呈极显著负相关,与单个子孙芋质量呈显著负相关.在此基础上,筛选出优异种质资源10份,其中包含3份特异种质资源.
Abstract
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.
