      Abstract
      Pemuliaan jagung pulut memerlukan informasi keragaan karakter galur yang digunakan untuk dijadikan sebagai tetua dalam perakitan varietas hibrida. Penelitian bertujuan mengevaluasi keragaaan galur-galur jagung pulut koleksi IPB dan mengidentifikasi galur yang potensial untuk dijadikan sebagai tetua dalam perakitan varietas hibrida. Penelitian dilaksanakan pada bulan November 2022- Februari 2023 di Kebun Percobaan PKHT Pasir Kuda dan Laboratorium Pendidikan Pemuliaan AGH. Penelitian terdiri atas 1 faktor, yaitu 15 genotipe galur jagung pulut koleksi IPB. Percobaan menggunakan rancangan kelompok lengkap teracak (RKLT) dengan tiga ulangan. Terdapat perbedaan karakter kuantitatif dan kualitatif dari galur-galur yang diamati. Hasil penelitian menunjukkan bahwa genotipe berpengaruh nyata terhadap semua karakter kuantitatif kecuali panjang daun. Terdapat keragaman karakter kualitatif pada galur-galur yang diamati kecuali karakter bentuk ujung daun. Produktivitas galur-galur jagung pulut pada penelitian berkisar 2,06-4,44 ton.ha-1 . Genotipe JPM1.5.19 memiliki produktivitas tertinggi dari semua galur jagung pulut yang diuji. Genotipe JPM1.5.19, JPS13.6.1P.10, dan JPS13.16.12.7 merupakan galur yang potensial untuk dijadikan sebagai tetua dalam perakitan jagung pulut hibrida.
       
      Waxy corn plant breeding requires information about the line characteristics used as parents in hybrid crosses. This study aimed to assess the performance of various lines of waxy corn from the IPB collection and identify which potential lines to serve as parents in hybrid crosses. The research was conducted from November 2022-February 2023 at the PKHT experimental field Pasir Kuda and the AGH Breeding Education Laboratory. The study consisted of single factor, i.e. 15 genotypes of waxy corn breeding lines of IPB collection. The experiment used a completely randomized block design (RCBD) with three replications. The results showed that there are differences in the quantitative and qualitative characteristics of the lines observed. Genotype significantly affected all quantitative characters except leaf length. There was a variety of qualitative characters in the observed lines except for the shape of the leaf tips. The productivity of various lines in this study ranged from 2.06-4.44 ton.ha-1 . Genotype JPM1.5.19 had the highest productivity of all evaluated waxy corn lines. Genotypes JPM1.5.19, JPS13.6.1P.10, and JPS13.16.12.7 are potential lines to be used as parents in hybrid waxy corn crossing.
