Genetic Diversity Test on Some Peanut Ecotypes (Arachis hypogaea L.) from Various Locations in the Tarutung Area

Introduction

Understanding the Importance of Genetic Diversity in Peanut Cultivation

Genetic diversity is a crucial aspect of plant breeding, as it allows for the development of crop varieties that are better adapted to specific environmental conditions. In the case of peanut cultivation, genetic diversity can play a significant role in determining the yield and quality of the crop. This study aims to evaluate the genetic diversity of various peanut ecotypes (Arachis hypogaea L.) from different locations in the Tarutung area, with the goal of identifying the most promising ecotypes for further breeding and development.

Background on Peanut Cultivation in the Tarutung Area

Peanut cultivation is an important crop in the Tarutung area, with many farmers relying on it as a primary source of income. However, the area's unique environmental conditions, including soil type and climate, can affect the yield and quality of the crop. In order to improve peanut cultivation in the Tarutung area, it is essential to understand the genetic diversity of the crop and identify the most suitable ecotypes for the region.

Methodology

Experimental Design and Materials

This study employed a random block design with five replications to evaluate the genetic diversity of four peanut ecotypes: Is Adancoting, Simaung-Maung, Stone Fence, and Pancur Napitu. The experiment was conducted in Tanjung Anom, Pancur Batu District, from December 2007 to March 2008. The ecotypes were tested for various parameters, including seed weight, plant height, number of branches, flowering time, and pod weight per plant.

Data Analysis

The data collected from the experiment were analyzed using statistical methods to determine the heritability of each parameter. Heritability is an important indicator in plant breeding, as it shows how much phenotypic variation can be inherited. In this study, the heritability of each parameter was calculated to determine the extent to which genetic factors influenced the variation.

Results

Comparison of Peanut Ecotypes

The results of the experiment showed that the Stone Fence ecotype (E3) had the highest seed weight, with an average weight of 208 grams. In contrast, the Adancoting ecotype (E1) had the lowest seed weight, with an average weight of 130 grams. The Simaung-Maung ecotype (E2) had an average seed weight of 155 grams, while the Pancur Napitu ecotype (E4) had an average seed weight of 175 grams.

Heritability Analysis

The heritability analysis revealed that the lowest heritability was found in the weight of 100 seeds and the weight of the pods per plot. This suggests that these characters have greater variations caused by environmental factors than genetic factors. Conversely, characters such as plant height, number of branches, and flowering time indicated high heritability, which means that existing variations are more influenced by genetic factors.

Discussion

Implications of the Results

The results of this study have significant implications for peanut cultivation in the Tarutung area. The Stone Fence ecotype, which had the highest seed weight, shows great potential for further breeding and development. In contrast, the Adancoting ecotype, which had the lowest seed weight, may require additional breeding efforts to improve its yield and quality.

Significance of the Study

This research is very important for the development of peanuts in the Tarutung and surrounding areas. By recognizing the ecotype that has the best results, farmers can choose the type of peanuts that are in accordance with environmental conditions in their area. In addition, the results of this study can be a reference for peanut breeding programs to develop superior and adaptive varieties of climate change and soil conditions.

Conclusion

Summary of the Study

In conclusion, this study aimed to evaluate the genetic diversity of various peanut ecotypes from different locations in the Tarutung area. The results showed that the Stone Fence ecotype had the highest seed weight, while the Adancoting ecotype had the lowest seed weight. The heritability analysis revealed that some characters, such as plant height and number of branches, have high heritability, while others, such as seed weight and pod weight, have low heritability.

Future Directions

This research is expected to provide broader benefits for the agricultural sector, especially in increasing the production of peanuts in Indonesia. Future studies can build on the findings of this research by conducting further breeding and development of the Stone Fence ecotype and other promising ecotypes. Additionally, researchers can explore the use of genetic markers to identify the genetic basis of the heritability of various characters in peanuts.
