Chromosomal Ploidy Identification of Taro (Colocasia) Germplasm Resources
摘要
Abstract
Chromosome ploidy of taro ( Colocasia ) germplasm resources, such as C. antiquorum Schott and C. esculenta ( L.) Schott, whose genotypes were the richest, were studied by flow cytometry analysis. The results showed that chromosome ploidy level of C. antiquorum Schott was diploid ( 2n= 2x=28 ). In C. esculenta ( L.) Schott, taro with large corm was diploid ( 2n=2x=28 ). The taro with multi-head and taro used for corm and cormels were triploid ( 2n=3x=42 ). Generally, taro with numerous cormels was triploid ( 2n=3x=42 ), while taro with numerous cormels, whose potile was purple-green and bud was white, was diploid ( 2n=2x=28 ). Meanwhile, there exists diploid ( 2n=2x=28 ) in taro with numerous cormels, whose petiole was green and it was introduced from India.关键词
