Korelasi Genetik Antar Peubah Komponen Hasil Dan Respons Seleksi Tidak Langsung Pada Populasi Tanaman Kacang Hijau
ABSTRACT
Mung bean (Vigna radiata L.) is one of Indonesia’s important food legumes with great potential for genetic improvement through plant breeding. This study aimed to determine the genetic correlation among yield components and the indirect selection response in mung bean populations to identify key traits for yield improvement. The research was conducted at the Experimental Farm of the Faculty of Agriculture, University of Riau, using a randomized block design (RBD) with one factor, consisting of 15 mung bean varieties and three replications. Data were analyzed for genetic variability, heritability, genetic correlation, and indirect selection response. The results showed significant differences among varieties for most observed traits. Broad genetic variability and high heritability were found in plant height, seed weight per plant, and seed yield per m2. Strong positive genetic correlations were observed between number of seeds per plant, seed weight per plant, and number of filled pods with yield. The highest indirect selection response for seed yield per square meter was obtained through seed weight per plant, followed by number of seeds per plant and number of filled pods. Therefore, seed weight per plant can serve as a key selection criterion for improving mung bean productivity.
