Analisis Hubungan Kekerabatan 10 Genotipe Tanaman Jagung (Zea Mays L.)

ABSTRACT
Maize (Zea mays L.) is a strategic food crop second only to rice, holding a vital role in national and global food security. Genetic diversity assessment is a crucial initial step in maize breeding to select optimal parental lines and maximize heterosis. This study aimed to analyze the genetic relationships among 10 maize genotypes based on their qualitative traits. The experiment was conducted at the Faculty of Agriculture, Universitas Riau, from June to September 2024, using a Randomized Block Design with 10 genotypes and 3 replications. Data analysis involved Principal Component Analysis (PCA) and Cluster Analysis. The PCA results showed that two principal components (PC1 and PC2) were sufficient to explain the major variation, accounting for 72.30% of the total variation. Cluster analysis, performed at a similarity level of 89.94% successfully grouped the ten genotypes into three distinct clusters. Cluster I consisted of NK212, Bisi 18, Betras 1, and Jantan F1; Cluster II included Anoman and Pulut Uri 1; and Cluster III was formed by Rasanya F1, Paramita F1, Jutawan F1, and Arumba. The smallest Euclidean genetic distance (0.00) was observed between the NK212 and Bisi 18 genotypes, indicating the highest degree of genetic similarity. The consistency between the PCA and cluster analysis confirms their complementary value in identifying genetic relationships and structuring the germplasm. These findings are valuable for selecting genetically distant parental lines for future maize breeding programs.
