Korelasi Genetik Berbagai Karakter Kacang Tanah (Arachis Hypogaea L.) Pada Berbagai Kondisi Pupuk Fosfor
ABSTRACT
Peanuts are an important food crop rich in fats and proteins. However, the low productivity of peanuts in Indonesia has led to a reliance on imports. One solution to increase productivity is the development of superior varieties through plant breeding approaches. This study aims to determine the genetic correlation of various peanut traits under different doses of phosphorus fertilizer. The research was conducted using a randomized block design (RBD) with two factors: six peanut varieties (Kancil, Katana 2, Garuda, Gajah, Tala 1, and Zebra) and three levels of phosphorus fertilizer doses (0, 45, and 63 kg P₂O₅ per hectare), resulting in 18 treatment combinations replicated three times. Observed parameters included flowering time, harvesting time, plant height, number of branches, number of seeds, and pod weight. The results revealed that flowering time, harvesting time, and number of seeds had a positive correlation with seed yield per unit area. Traits with high heritability, such as flowering time and number of seeds, are more effective for selection purposes. This study contributes to peanut breeding by focusing on genetic traits that directly influence yield, thereby enabling more efficient productivity improvements.
