Abstract
Pertumbuhan tomat pada lingkungan berbeda memberikan perbedaan hasil karena adanya interaksi genetik x lingkungan yang mempengaruhi ekspresi suatu gen pada kondisi lingkungan tertentu. Penelitian ini bertujuan untuk menduga nilai ragam genetik serta nilai heritabilitas arti luas pada genotip tomat tipe determinate di dua lingkungan tanam. Penelitian dilakukan dari Maret hingga Juli 2021 dengan menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) di dua lingkungan tanam (Depok dan Jakarta). Perlakuan terdiri dari 3 genotip tomat generasi F6 dan 2 varietas komersil diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa lingkungan tanam memberikan pengaruh terhadap pertumbuhan dan perkembangan genotip tomat yang digunakan. Nilai ragam genetik pada setiap karakter tergolong dalam kriteria sempit, kecuali pada karakter tebal daging buah dan luas daun. Nilai heritabilitas arti luas terhadap karakter yang diamati menunjukkan kriteria tinggi, kecuali pada karakter diameter buah (kriteria sedang) dan karakter tinggi tanaman (kriteria rendah). Genotip RwTa-4-10U-6U-4U-2U memberikan penampilan terbaik pada kedua lokasi tanam, dengan tinggi tanaman lebih rendah (91,09 cm), diameter batang lebih kekar (9,69 mm), buah lebih panjang (5,64 cm), diameter buah lebih besar (4,25 cm), total padatan terlarut lebih tinggi (5,22ºBrix), bobot per buah lebih besar (48,43 g), serta umur berbunga lebih genjah (25 HST) dibandingkan varietas Tantyna dan varietas Tora.ABSTRACTTomatoes growth in different environments give different results due to genetic x environment interaction that affect the expression of genes in a certain environmental condition.
