芋种质资源颜色性状多样性观察

         

摘要

为了探究芋种质资源颜色性状的变化规律,以保存在国家种质武汉水生蔬菜资源圃的300多份芋种质资源为材料,按照《农作物种质资源鉴定评价技术规范芋》对芋种质资源的颜色性状进行观察和归类,并重点对芋的叶心色斑颜色、叶柄中下部颜色及母芋芽色的相关性进行总结和探讨。根据叶柄中下部颜色将滇南芋分为绿柄野芋(白芽类型)、乌绿柄野芋(红芽类型)和紫柄野芋(白芽类型)3个类型;将芋中的多子芋分为绿柄多子芋(一般为白芽类型)、乌绿柄多子芋(一般为红芽类型)和红紫柄多子芋(白芽类型)3个基本类型,将芋中的多头芋分为绿柄多头芋(白芽类型)和乌绿柄多头芋(红芽类型)2个类型。从滇南芋和芋的整体来看,只要叶柄中下部颜色含有乌绿色成分,则母芋芽色一般为红色类型。从叶心色斑颜色来看,滇南芋中的绿色者,母芋芽色为白色类型;紫红色或紫色者,母芋芽色可能为白色类型,也可能为红色类型。芋中,多子芋叶心色斑颜色为紫红色者,母芋芽色为红色类型;黄绿色或绿色者,母芋芽色为白色类型。多头芋中,叶心色斑颜色为绿色者,母芋芽色为红色类型;紫红色者,母芋芽色为白色类型。%In order to find out the changing rule of color characters of taro germplasm resource,we observed and classified the color character diversities of taro 〔Colocasia antiquorum Schott andColocasia esculenta (L.) Schott〕 germplasm resource according to the Technical Code for Evaluating Crop Germplasm Resources-Taro 〔Colocasia esculenta (L.) Schott〕,taking over 300 taro germplasm resources conserved in Wuhan National Germplasm Repository for Aquatic Vegetables. We summarized and focused on the correlation between leaf junction color,color of middle to lower part of petiole,and bud color of corm. According to the color of middle to lower part of petiole,C. antiquorum Schott was divided into 3 types as wild taro with green-petiole(white bud type), wild taro with purple-green-petiole (red bud type) and purple-petiole(white bud type). InC. esculenta (L.) Schott,taro with numerous cormels was divided into 3 basic types of green-petiole taro with numerous cormels (white bud type generally),purple-green-petiole taro with numerous cormels (red bud type generally) and red-purple-petiole taro with numerous cormels (white bud type generally). Taro with multi-headed corm was divided into 2 types of green-petiole-taro with multi-headed corm (white bud type) and purple-green-petiole taro with multi-headed corm (red bud type). Looking from the whole ofC. antiquorum Schott andC. esculenta (L.) Schott,if there was purple-green color component in the color of middle to lower part of petiole,its bud color of corm was red type and the others were white type generally. Looking from leaf junction color,inC. antiquorum Schott,that of green was white bud type and that of purple-red was white bud type or red bud type. InC. esculenta (L.) Schott,if the leaf junction color of taro with numerous cormels was purple-red,its bud color of corm was red type,and if that was yellow-green or green,its bud color of corm was white type. In taro with multi-headed corm,if the leaf junction color was green,its bud color of corm was red type,and if that was purple-red,its bud color of corm was white type.
