Genetic Parameters Estimation of Unipa Red Waxy Corn Intercropped with Peanuts in Susweni Land, East Manokwari District

Corn is the second staple food after rice in Indonesia. The productivity of dry corn kernels with a water content of 14 percent in West Papua was 6,481 tons in 2022 and decreased to 4,623 tons in 2023. Estimating genetic parameters is essential before improving any trait. Genetic parameters in plants typically include the genetic diversity coefficient, heritability, and correlation between plant traits. Observation data were statistically analyzed using analysis of variance (ANOVA). The ANOVA results were used to obtain values for the Variance Partition, Genetic Coefficient of Variation (GCV), Phenotype Coefficient of Variation (PCV), and Heritability. The correlation between traits was analyzed using the Costat program version 6.311. The observations revealed that the PCV was higher than the GCV in corn plants, indicating that environmental factors more dominantly influence visual character diversity (phenotype). Some narrow sense heritability values were negative for several traits of the Unipa glutinous red corn plants. The weight of corn cob showed a very high correlation without the husk and with the husk (r=0.93), while a very low correlation was observed between the width of the leaves at 7 WAP and the diameter of the stem at 1 WAP (r=-0.38)
