Identification of Cassava (Manihot esculenta Crantz.) Morpho-physiological Traits in the Toba Regency

Abstract

In Toba, cassava is the third most important crop after food crops (rice and maize) and secondary crops (soybeans and peanuts). Previously, research in Toba Regency had never been conducted on the morphology and physiology of cassava. Various villages infact, in several locations in Toba Regency produce different varieties of cassava. Finally, this research was done. Identifying the morphological, physiological, and related characteristics of cassava (Manihot esculenta Crantz.) in Toba Regency is the aim of this study. In October 2018, the research was conducted in Toba Samosir Regency, but in 2020 it has become Toba Regency. Two villages from the same sub-district were chosen as research sites for this study, which was conducted utilizing a descriptor guide and descriptive analytic methods using a sample area in Toba Regency, that are Pintu Bosi and Sidulang. At the research location, seven genotypes of cassava have been identified: G1, G2, G3, G4, G5, G6, and G7. The genotype of G1 and G5 display the Euclidean square values with the lowest values, while G3 and G7 display the greatest values. There are one, two, and three kinship groupings with a disagreement scale of 11%, 17%, and 25% in the dendogram that was created.
