Study of Morphological and Agronomic Characteristics of Three Genotypes of Sweet Potato (Ipomoea batatas L.) from North Sumatra

Introduction

Sweet potatoes (Ipomoea Batatas L.) are one of the most widely consumed food plants globally, with a rich genetic diversity that has been exploited for centuries. Despite their popularity, there are still many sweet potato genotypes whose characteristics have not been fully identified, hindering their potential for development and improvement. This study aims to bridge this knowledge gap by investigating the morphological and agronomic characteristics of three sweet potato genotypes originating from North Sumatra.

Background

North Sumatra, a region in Indonesia, is known for its rich agricultural heritage, with sweet potatoes being one of the staple crops. However, the genetic diversity of sweet potatoes in this region remains largely unexplored, limiting the potential for crop improvement and development. This study seeks to address this knowledge gap by identifying the morphological and agronomic characteristics of three sweet potato genotypes from North Sumatra.

Methodology

This study was conducted on Jalan Harmonika Pasar 1, Padang Bulan Selayang II, Medan City, with a height of about 25 meters above sea level, during the period August to November 2021. The design used in this study was a random design group (RAK) one factor, with a focus on three sweet potato genotypes namely Perbaungan, Noni Bay, and Padang Sidimpuan. Identification of morphological characters was carried out based on the Sweet Potato Descriptor Guide compiled by IPGRI.

Results

The results of this study showed that there were significant differences in the morphological and agronomic characters between the three tested genotypes, with an exception to the average parameter of tubers. Padang Sidimpuan genotype recorded the highest yields in several parameters, including tubers length, tubers per sample, tuber diameter, and organoleptic tests. This discovery shows that Padang Sidimpuan genotype has the potential to be superior in tubers production.

Furthermore, this study also noted that the coefficient of genetic diversity and the highest phenotypic diversity coefficient found in observed parameters such as tendril length, tuber weight per sample, tuber diameter per sample, and the average weight of tubers. This shows a high variation between individuals in each genotype, which can be utilized in plant breeding programs to improve the quality and quantity of sweet potato production in the future.

Discussion

The results of this study have significant implications for the development of sweet potatoes in Indonesia, particularly in North Sumatra. The identification of morphological and agronomic characteristics of various genotypes can provide valuable information for farmers and researchers in choosing the right varieties to be planted in accordance with environmental conditions and market needs. This study also highlights the potential of sweet potatoes as a source of food and as an economic commodity, which can contribute to community food security.

Conclusion

In conclusion, this study has provided valuable insights into the morphological and agronomic characteristics of three sweet potato genotypes from North Sumatra. The results of this study have significant implications for the development of sweet potatoes in Indonesia, particularly in North Sumatra. The identification of morphological and agronomic characteristics of various genotypes can provide valuable information for farmers and researchers in choosing the right varieties to be planted in accordance with environmental conditions and market needs.

Recommendations

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

Further research: Further research is needed to explore the genetic diversity of sweet potatoes in North Sumatra and to identify new genotypes with desirable characteristics.
Breeding programs: Breeding programs should be established to improve the quality and quantity of sweet potato production in North Sumatra.
Variety selection: Farmers and researchers should select varieties that are suitable for the environmental conditions and market needs of North Sumatra.
Community engagement: Community engagement and outreach programs should be established to promote the development of sweet potatoes in North Sumatra and to raise awareness about the importance of sweet potatoes as a source of food and as an economic commodity.

Limitations

This study has several limitations, including:

Sample size: The sample size of this study was limited to three genotypes, which may not be representative of the entire population of sweet potatoes in North Sumatra.
Environmental factors: The study was conducted in a single location, which may not be representative of the entire region.
Methodology: The study used a random design group (RAK) one factor, which may not be the most effective design for this study.

Future Directions

Future studies should aim to:

Explore genetic diversity: Explore the genetic diversity of sweet potatoes in North Sumatra and to identify new genotypes with desirable characteristics.
Develop breeding programs: Develop breeding programs to improve the quality and quantity of sweet potato production in North Sumatra.
Promote community engagement: Promote community engagement and outreach programs to raise awareness about the importance of sweet potatoes as a source of food and as an economic commodity.
