      Abstract
      Tomat (Lycopersicum esculentum L.) merupakan komoditas sayuran buah penting di Indonesia digunakan sebagai bahan sayur atau konsumsi langsung, karena manfaatnya sebagai sumber vitamin, mineral dan serat bagi masyarakat Indonesia. Peningkatan jumlah penduduk dan kesadaran terhadap nilai gizi menuntut peningkatan ketersediaan, tomat. Untuk memenuhi kebutuhan tersebut dibutuhkan varietas unggul secara berkelanjutan yang harus diuji daya hasilnya. Penelitian ini bertujuan untuk mengatahui potensi daya hasil 11 (sebelas) genotipe koleksi PKHT dibandingkan dengan tiga varietas komersial. Sebanyak 14 genotipe ditanam menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan tiga ulangan di kebun percobaan PKHT Tajur. Hasil analisis ragam menujukan bahwa untuk semua 12 karakter vegetatif, reproduktif dan produksi hanya karakter diameter batang yang tidak berbeda diantara genotipe yang diuji. Analisis selanjutnya menunjukan bahwa genotipe IPBT34, IPBT43, IPBT57, IPBT60 dan IPBT64 menunjukan potensi hasil yang tidak berbeda dengan varietas pembanding. Genotipe IPBT8, IPBT43, IPBT64 dan IPBT 78 menunjukan bobot per buah yang tidak berbeda dengan varietas pembanding. Analisis Mix Variable Selection Index (MVSI) dengan mempertimbangkan umur panen, ukuran buah, dan produktifitas menunjukan bahwa genotipe IPBT43, IPBT64 berpotensi untuk dijadikan varietas unggul komersial.
       
      Tomato (Lycopersicum esculentum L.) is an important fruit vegetable commodity in Indonesia that’s use as fresh consumption or condiment, due to its role as a source of vitamins, minerals, and dietary fiber for the population. The increasing population and growing awareness of nutritional value demand a higher availability of tomatoes. To meet this demand, the development of superior varieties on a sustainable basis is essential, which requires yield performance testing. This study aimed to evaluate the yield potential of 11 (eleven) genotypes from the PKHT collection compared to three commercial varieties. A total of 14 genotypes were cultivated using a Randomized Complete Block Design (RCBD) with three replications at the PKHT Tajur experimental field. Analysis of variance revealed that among the 12 vegetative, reproductive, and yield traits observed, only stem diameter showed no significant difference among the tested genotypes. Further analysis indicated that genotypes IPBT34, IPBT43, IPBT57, IPBT60, and IPBT64 exhibited yield potential comparable to the commercial varieties. Meanwhile, genotypes IPBT8, IPBT43, IPBT64, and IPBT78 demonstrated average fruit weight similar to the control varieties. The Mix Variable Selection Index (MVSI) analysis, which considered harvest age, fruit size, and productivity, identified genotypes IPBT43 and IPBT64 as promising candidates for future commercial superior varieties.
