Identification of Vegetative and Generative Characters in Several Populations of Black Corn Genotypes and Purple Corn

Understanding the Genetic Diversity of Black and Purple Corn

Differences in characteristics between black corn and purple corn can be influenced by genetic factors and the environment in which they grow. High genetic diversity and significant heritability can be used as a basis in the selection process in plant breeding programs. This study aims to identify genetic diversity and heritability values in vegetative and generative characters of several black and purple genotypes.

Research Methodology

The study was conducted at UPTD BI Palawija Tanjung Selamat, Medan Sunggal District, Deli Serdang Regency, Medan, with a height of ± 43 meters above sea level, from September to December 2021. Research design uses a random design group with one factor consisting of four Corn genotypes, namely Black Aztec, Dwarf Blue Jade, Srikandi Ungu 1, and Maiz Morado.

Observed characteristics are divided into two main groups: vegetative characters and generative characters. Vegetative characters include plant length, number of leaves, and stem diameter. While generative characters include male flowering time, female flowering time, harvest time, cob length, cob diameter, cob weight per plant, and 100 seed weight.

Research Results

The results showed that there were significant variations in vegetative and generative characters among each corn genotype. The high genetic diversity coefficient is found in the character of the weight of the cob per plant and the weight of 100 seeds, which indicates the potential for a good selection for genetic increases in these characters. On the other hand, the coefficient of moderate genetic diversity is in the length and diameter of the cob, while the length of the plant, the number of leaves, the diameter of the stem, and the time of the appearance of male and female flowers indicates the coefficient of low genetic diversity.

Furthermore, high heritability values are found in the harvest age character of the four corn genotypes studied. This indicates that the character is strongly influenced by genetic factors, so it can be expected that the results of better breeding if selection is based on the character.

Analysis and Discussion

Knowing the genetic diversity and heritability of vegetative and generative characters is an important step in plant breeding. Character with a high genetic diversity coefficient shows a significant variation in the population, which can be used as a basis for the selection of superior individuals. Conversely, characters with low genetic diversity may not show adequate variations for the selection process, so that it becomes less effective as a target of breeding.

The results showing the high heritability value at harvest age are very important, because this shows that individuals who have harvest age can be derived to their offspring. Therefore, breeding to shorten the age of harvest can be focused on genotypes with these characters to improve the efficiency of corn production.

In the context of sustainable agriculture, understanding of genetic diversity and heritability is not only useful for increasing results, but also to develop varieties that are more resistant to climate and disease change. Thus, black and purple corn breeders are expected to increase food security and support food diversity in the community.

Implications of the Study

Overall, this research provides an important insight into the characteristics of black and purple corn genotypes, as well as its relevance in the sustainable plant breeding program. By utilizing existing genetic diversity, it is hoped that superior varieties can be obtained that can meet the needs of consumers and increase agricultural production.

The study's findings can be used as a basis for further research in plant breeding, particularly in the development of new varieties of black and purple corn. Additionally, the study's results can be used to inform breeding programs and selection strategies for corn breeders.

Conclusion

In conclusion, this study has identified significant variations in vegetative and generative characters among black and purple corn genotypes. The study's findings highlight the importance of genetic diversity and heritability in plant breeding and provide valuable insights for corn breeders. By understanding the genetic diversity and heritability of black and purple corn, breeders can develop superior varieties that meet the needs of consumers and increase agricultural production.

Recommendations

Based on the study's findings, the following recommendations are made:

Further research is needed to explore the genetic diversity and heritability of other characters in black and purple corn.

The study was conducted in a single location, which may limit the generalizability of the findings.
The study only examined four corn genotypes, which may not be representative of the broader population of black and purple corn.
The study did not examine the effects of environmental factors on the genetic diversity and heritability of black and purple corn.

Future Directions

Future research should aim to address the limitations of this study and explore the genetic diversity and heritability of other characters in black and purple corn. Additionally, further research is needed to explore the effects of environmental factors on the genetic diversity and heritability of black and purple corn.

Conclusion

In conclusion, this study has provided valuable insights into the characteristics of black and purple corn genotypes and their relevance in the sustainable plant breeding program. By understanding the genetic diversity and heritability of black and purple corn, breeders can develop superior varieties that meet the needs of consumers and increase agricultural production.
