Abstract

Identifikasi tanaman melon yang tahan terhadap cekaman kekeringan merupakan solusi untuk meningkatkan produktivitas tanaman melon pada lahan kering. Tujuan penelitian adalah identifikasi karakter-karakter melon dan menyeleksi toleransi melon terhadap cekaman kekeringan. Penelitian menggunakan Rancangan Acak Kelompok faktorial yang terdiri dari 2 faktor. Faktor pertama terdiri dari 10 taraf genotip tanaman melon dan faktor kedua terdiri dari 2 taraf, yaitu Irigasi 100% (100% kapasitas lapang) dan irigasi 50% (50% kapasitas lapang). Penelitian terdiri dari 20 kombinasi perlakuan dan diulang sebanyak 3 ulangan sehingga dihasilkan 60 unit percobaan. Tiap unit percobaan terdiri dari 5 tanaman dan pengamatan dilakukan pada 3 tanaman sampel pada setiap unit percobaan. Karakter tanaman yang diamati adalah umur berbunga jantan, umur berbunga betina, umur panen, kadar gula (^oBrix), bentuk buah, warna kulit buah, warna buah, net pada kulit buah, panjang buah, diameter buah, tebal daging buah, berat buah, dan produksi per hektar. Hasil penelitian menunjukkan bahwa cekaman kekeringan menurunkan produksi per hektar sebesar 26.36%. Nilai ISK rata-rata menunjukkan bahwa terdapat 3 genotip yang toleran terhadap cekaman kekeringan dan 7 genotip yang tidak tahan terhadap cekaman kekeringan. Tanaman melon yang direkomendasikan untuk dikembangkan pada lahan kering adalah G2, G3, G5, dan G6.
