Chromosome Number of Cultivated Local Taro (Calocasia esculenta (L.) Schott) in Surin Province, Thailand
Keywords:
Chromosome Number, Native Taro, Surin ProvinceAbstract
This research aimed to study chromosome number and classify cultivated taro in Surin of 7 strains, namely Trow Sla (Pheuk Mag), Trow Gon (Pheuk Loog), Trow Kyong Gahom (Pheuk Hoy Deang), Trow Gamoon (Pheuk Tean), Trow Poang Laloa (Pheuk Khai Nog Khao), Trow Khmoa (Pheak Dum), and Trow Pa Am (Pheuk Whan). Apical root meristem of each taro were study somatic chromosome number using Acetocarmine Squash Technique.
The result revealed that there are two kinds karyotype of taro; diploid (2n=28) and triploid (3n=42). Three strains of Surin cultivated taro has chromosome count of 2n=28, namely Trow Sla, Trow Pa Am and Trow Khmoa. These three strains were dasheen cultivated type. In addition, four strains of Surin cultivated taro has chromosome number of 3n=42, namely Trow Gon, Trow Kyong Gahom, Trow Gamoon, and Trow Poang Laloa. These four strains were eddoe cultivated type.
