Introduction

The Araceae crop, commonly known as taro, is a staple food in many parts of the world, including Indonesia. In Labuhan Batu Selatan Regency, North Sumatra Province, taro is an important crop for local farmers, providing a source of income and food for the community. However, the morphological characteristics of taro plants in this region have not been well-documented, making it difficult to identify superior genotypes for cultivation.

This study aims to identify the morphological characteristics of taro plants (Araceae) that grew in Labuhan Batu Selatan Regency, North Sumatra. The study was conducted over a period of two months, from September to October 2021, using a survey method that refers to the IPGRI (International Plant Genetic Resources Institute) descriptors. The sampling technique used was accidental sampling.

Methodology

The researchers observed various morphological parameters of taro plants, including:

Leaf Stranding Patterns

The shape of the leaves of the leaf can also affect the yield and quality of the tubers. The leaves can be flat, jagged, or curved.

Leaf Strands

The base color of the leaves can also affect the yield and quality of the tubers. The base color can be green, dark green, or light green.

Leaf Strand Color

The color of the leaves of the leaf can also affect the yield and quality of the tubers. The color can be different from the base color of the leaf strands.

Connection Pattern on the Leaves

The shape of the connection between the leaf stalks and leaf strands can also affect the yield and quality of the tubers.

The Color of the Sap of the Leafy Tip

The color of the sap coming out of the tip of the leaf when it is cut or damaged can also affect the yield and quality of the tubers.

Length/ Width Ratio of Leaf Lamina

The ratio between the length and width of the leaf strands can also affect the yield and quality of the tubers.

Main Color of Leaf Bone

The length of the leaf stalk from the base to the tip that sticks to the leaf strands can also affect the yield and quality of the tubers.

Color of Leaf Stalk

The color of the leaf stalks can also affect the yield and quality of the tubers.

Lower Cross Section of the Leaf Stalk

The lower cross section of the leaf stalk can also affect the yield and quality of the tubers.

The Color of the Leaf Midrib

The color of the leaf midrib that surrounds the taro plant stems can also affect the yield and quality of the tubers.

The Edge Color of the Leaf Midrib

The edge color of the leaf midrib can also affect the yield and quality of the tubers.

Length of Tubers

The length of the taro tubers from the end to the other end can also affect the yield and quality of the tubers.

Tuber Diameter

The diameter of the taro tuber on the widest part can also affect the yield and quality of the tubers.

Branching Tubers

The number and form of taro tuber branching can also affect the yield and quality of the tubers.

The Shape of the Tubers

The general shape of taro tubers can also affect the yield and quality of the tubers.

Tuber Weight

The weight of taro tubers can also affect the yield and quality of the tubers.

The Color of the Tuber Cortex

The outer skin color of taro tubers can also affect the yield and quality of the tubers.

The Color of the Middle Tuber Meat

The color of taro tubers in the middle can also affect the yield and quality of the tubers.

Surface of Tubers

The texture of the surface of the tubers of the tubers can also affect the yield and quality of the tubers.

Thickness of Tubers

The thickness of the tubers of taro tubers can also affect the yield and quality of the tubers.

Number of Kormel

The number of tubers (kormel) that grow around the parent tubers can also affect the yield and quality of the tubers.

Plant Production

The number of taro tubers produced per plant can also affect the yield and quality of the tubers.

Root Color

The color of taro plant roots can also affect the yield and quality of the tubers.

Results

The results of the study showed that there were 13 genotypes of taro in Labuhan Batu Selatan Regency, which were divided into two types, namely Xanthosoma sp and Colocasia. Data analysis using dendograms shows the existence of kinship between taro genotypes. S2 and S13 genotypes have the closest kinship with the value of 4,223 sissimiliarity, while S1 and S2 genotypes have the farthest kinship with 7,797 disssimiliarity.

Conclusion

This study shows a significant morphological diversity in taro plants in Labuhan Batu Selatan. This data has the potential to be used in the conservation and development program of taro cultivation, especially in an effort to choose superior genotypes that have the potential to produce larger and high-quality tubers.

Recommendations

Based on the results of this study, the following recommendations are made:

Further research is needed to identify the genetic diversity of taro plants in Labuhan Batu Selatan Regency.
The morphological characteristics of taro plants should be used as a selection criterion for superior genotypes.
