Vegetative and Generative Character Diversity Test of several soybean varieties (Glycine Max L.) with the Row System
Introduction
The soybean plant is one of the most widely cultivated legumes in the world, with Indonesia being one of the largest producers of soybeans. The country's climate and soil conditions make it an ideal place for soybean cultivation, and the crop is an important source of protein and income for many farmers. However, soybean production in Indonesia is facing several challenges, including low yields, poor quality, and limited genetic diversity. To address these challenges, it is essential to understand the genetic diversity of soybean varieties and to develop more effective cultivation strategies.
Methodology
This study aims to examine differences in vegetative and generative characters among several soybean varieties (Glycine max L.). The study was conducted on the research land of the Faculty of Agriculture, University of North Sumatra from March to June 2010. The method used in this study was a non-factorial random design. The varieties tested include white fans, red fans, Anjasmoro, and Wilis.
The study used a total of 16 parameters to evaluate the vegetative and generative characters of the soybean varieties. These parameters include the periods of the V2, V3, and V4 periods, the generative stages of R1, R2, and R8, plant height, the number of branches on the main stem in the R8 stage, the flowering date (R1), the date of the aging (senescence), the number of empty pods per plant in the R8 stage, the number of seeds per plant in the R8 stage, and weighs 100 seeds in the R8 stage.
Results
The results of this study showed that there were significant differences between varieties in the periods of the V2, V3, and V4 periods and at the generative stages of R1, R2, and R8. In addition, plant height also shows a significant difference from stages V1 to V9, as well as at stages of R3 to R8. Other measured variables include the number of branches on the main stem in the R8 stage, the flowering date (R1), the date of the aging (senescence), the number of empty pods per plant in the R8 stage, the number of seeds per plant in the R8 stage, and weighs 100 seeds in the R8 stage.
Discussion
One of the interesting findings of this study is that high genetic variance values ​​are found in the parameter of the number of empty pods per plant, the number of branches on the main stem, and seed weight per plant. On the other hand, the other four parameters show the value of low genetic variance, namely the date of the stages, the flowering date (R1), the date of aging, and the full aging date (R8). This shows that certain characters have more genetic variations than others, which can be utilized in soybean breeding to increase yields.
The high heredity value is also observed in the weight parameter of 100 seeds, the flowering date (R1), the weight of the seeds per plant, and the height of the plant. Meanwhile, the value of heredity is being found in the parameter of the stage date, the number of branches per plant, and the number of pods per plant. However, one parameter, namely the number of productive branches per plant, shows a low heredity value.
Conclusion
This study provides an important insight into genetic diversity in soybean varieties, which can be the basis for plant breeders in choosing superior varieties to increase soybean productivity and competitiveness. In addition, understanding of vegetative and generative characters also helps in the development of more effective cultivation strategies, which can contribute to improving overall agricultural products.
Recommendations
From the results of this study, it is expected to be a reference for further research and application in the field to optimize soybean production in Indonesia. The study suggests that plant breeders should focus on developing soybean varieties with high genetic variance values, particularly in the parameters of the number of empty pods per plant, the number of branches on the main stem, and seed weight per plant. Additionally, the study recommends that farmers should adopt more effective cultivation strategies, such as using high-yielding varieties, optimizing fertilization and irrigation, and controlling pests and diseases.
Limitations
This study has several limitations. Firstly, the study was conducted on a limited number of soybean varieties, which may not be representative of the entire soybean population in Indonesia. Secondly, the study used a non-factorial random design, which may not be able to capture the interactions between different variables. Finally, the study did not consider the environmental factors that may affect soybean production.
Future Research Directions
Future research should focus on developing more effective cultivation strategies for soybean production in Indonesia. This can be achieved by conducting more extensive studies on the genetic diversity of soybean varieties, as well as by developing more effective pest and disease management strategies. Additionally, research should be conducted on the environmental factors that affect soybean production, such as climate change and soil degradation.
Conclusion
In conclusion, this study provides an important insight into genetic diversity in soybean varieties, which can be the basis for plant breeders in choosing superior varieties to increase soybean productivity and competitiveness. The study also highlights the importance of understanding vegetative and generative characters in developing more effective cultivation strategies. Future research should focus on developing more effective cultivation strategies for soybean production in Indonesia, as well as on understanding the environmental factors that affect soybean production.
