      Abstract
      Pengembangan ideotipe kacang hijau dengan periode panen pendek dan produksi tinggi diharapkan berimplikasi pada peningkatan produktivitas. Penelitian ini bertujuan mengevaluasi karakter agronomi dan produksi galur-galur kacang hijau IPB hasil seleksi panen pendek. Penelitian dilaksanakan pada November 2023 hingga Februari 2024 di Kebun Percobaan Leuwikopo IPB. Penelitian ini menguji 17 galur kacang hijau IPB dan tiga varietas nasional (Vima 1, Vima 2, Vima 5) dalam rancangan kelompok lengkap teracak dengan tiga ulangan. Karakter yang diamati meliputi karakter kuantitatif dan kualitatif. Hasil penelitian menunjukkan pengaruh nyata genotipe terhadap karakter jumlah tanaman per plot, umur berbunga dan bobot polong per tanaman. Heritabilitas arti luas (h2 bs) karakter kuantitatif dalam populasi yang diuji berada pada kriteria rendah hingga tinggi. Prediksi produktivitas sangat dipengaruhi oleh faktor lingkungan dan berkorelasi positif nyata dengan bobot polong per plot, positif sangat nyata dengan bobot biji per plot serta berkorelasi negatif nyata dengan bobot biji per tanaman. Galur – galur kacang hijau yang diuji mengelompok menjadi enam klaster berdasarkan tingkat kemiripan 33,33% karakter kuantitatif dan kualitatif yang diukur dengan jarak euclidean. Genotipe F7-VR480B-109 memiliki potensi produktivitas yang lebih tinggi dari genotipe uji lainnya, serta genotipe F7-Lom2/V2-24 dan F7-Lom2/V2-6 memiliki produktivitas cenderung sama baik dengan varietas pembanding.
       
      The development of mung bean ideotypes with a short harvest period and high yield is expected to enhance productivity. This study aimed to evaluate the agronomic traits and yield potential of IPB mung bean lines selected for early maturity. The experiment was conducted from November 2023 to February 2024 at the IPB Leuwikopo Experimental Field, using 17 IPB mung bean lines and three national varieties (Vima 1, Vima 2, and Vima 5) arranged in a randomized complete block design with three replications. Observations included both quantitative and qualitative traits. The results revealed significant genotypic effects on the number of plants per plot, days to flowering, and pod weight per plant. Broad-sense heritability (h²bs) for quantitative traits ranged from low to high. Yield prediction was significantly influenced by environmental factors and showed a positive correlation with pod weight per plot, a highly significant positive correlation with seed weight per plot, and a significant negative correlation with seed weight per plant. Cluster analysis grouped the genotypes into six clusters based on 33,33% similarity in measured traits using Euclidean distance. The genotype F7-VR480B- 109 demonstrated higher yield potential than the other tested lines, while genotypes F7-Lom2/V2-24 and F7-Lom2/V2-6 showed productivity comparable to the check varieties.
