Eksplorasi dan Identifikasi Karakter Agronomi Bawang Merah Lokal Samosir (Allium ascalonicum L.) di Kabupaten Humbang Hasundutan dan Samosir

Abstract

In order to meet the need for shallots in North Sumatra, the Government imported shallots which resulted in the transition of local onions to introduced onions and resulted in local Samosir shallots becoming scarce. Therefore, efforts are being made to prevent the extinction of local Samosir shallots such as inventory, collection, characterization and evaluation. This research aims to identify the agronomic characteristics of local Samosir shallots in Humbang Hasundutan and Samosir Regencies. This research was conducted in Humbang Hasundutan and Samosir Regencies in August-January 2024, using a survey method with stages, namely, exploration, characterization, identification and data analysis. The results of the research show that in Humbang Hasundutan Regency there are 10 accessions of local Samosir shallots and in Samosir Regency there are 5 accessions of local Samosir shallots. Results of morphological characteristics for leaf color (dark green, green, gray green), leaf shape (hollow cylindrical), leaf texture (medium, strong), leaf density (low, medium), leaf position (medium), flower color ( white), tuber shape (globe, broad oval and broad elliptic) and tuber color (purple/white). Based on dendogram analysis, it was found that the closest kinship relationships were the Tipang 1 and Tipang 2 accessions with a dissimilarity value of 0.00% and the furthest kinship relationships were the Tanjung Bunga accession and the Turpuk Sihotang accession with a dissimilarity value of 7.45%.
