Abstract

Perakitan varietas melon hibrida dengan karakter-karaker unggul merupakan suatu upaya untuk memenuhi kebutuhan benih melon dalam negeri dan mengurangi ketergantungan impor benih melon dari luar negeri. Tujuan penelitian ini adalah untuk mengevaluasi penampilan fenotipik 24 genotip tanaman melon hibrida (F1).  Penelitian ini dilakukan di Kebun Percobaan Agroteknologi Fakultas Pertanian Universitas Trunojoyo Madura pada bulan Februari sampai Mei 2019. Bahan yang digunakan adalah 24 genotip melon hibrida (F1) hasil persilangan di antara galur-galur melon. Penelitian ini menggunakan Rancangan Acak Kelompok dengan satu perlakuan yaitu genotip dan diulang sebanyak 3 kali. Analisis data menggunakan analisis varians (Anova) yang dilanjutkan dengan uji Duncan pada taraf 5%. Nilai heritabilitas dalam arti luas dihitung menggunakan taksiran nilai kuadrat tengah pada analisis varians. Seleksi indeks digunakan untuk mendapatkan kandidat varietas tanaman melon hibrida. Hasil penelitian menunjukkan bahwa 24 tanaman melon hibrida (F1) yang diuji memiliki perbedaan penampilan pada karakter umur berbunga, panjang buah, diameter buah, tebal daging buah, kadar gula, jumlah biji per buah, bobot buah per tanaman dan produksi per hektar. Nilai heritabilitas dalam arti luas tanaman melon hibrida (F1) pada karakter yang dievaluasi berkisar antara 0,15 – 0,71. Hasil  nilai seleksi indeks terboboti menunjukkan bahwa terdapat dua calon varietas tanaman melon hibrida yang memiliki seleksi indeks tertinggi yaitu G4 dan G5. 

 

ABSTRACT

Assembling hybrid melon varieties with superior characters is an effort to meet the needs of domestic melon seeds and reduce dependence on imported melon seeds. The purpose of this study was to evaluate the phenotypic appearance of 24 genotypes of hybrid melon plants (F1).  This research was conducted at the Agrotechnology Experimental Field at Faculty of Agriculture, Universitas Trunojoyo Madura from February to May 2019.
