Uji Daya Hasil Genotipe Mutan Harapan untuk Perakitan Tomat Toleran Pecah Buah di Dataran Rendah

Abstract

Pecah buah merupakan salah satu gangguan fisiologis yang terjadi pada tanaman tomat. Pecah buah dapat mengurangi hasil produksi dan berdampak nyata pada kerugian buah yang dapat dipasarkan. Penelitian ini bertujuan untuk menguji genotipe-genotipe mutan yang toleran pecah buah dan berproduksi tinggi. Penelitian ini dilaksanakan pada bulan Juli-November 2019 di Kebun Percobaan Leuwikopo IPB, Dramaga, Bogor, Jawa Barat. Percobaan dilakukan menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan satu faktor yaitu perlakuan genotipe tomat mutan dengan 13 taraf. Penelitian dilakukan dengan tiga ulangan sehingga diperoleh 39 satuan percobaan. Hasil penelitian menunjukan bahwa perlakuan genotipe memberikan pengaruh nyata pada beberapa karakter seperti tinggi tanaman, diameter buah, panjang buah, bobot per buah, bobot buah per tanaman, dan produktivitas. Genotipe M5/990 Kudamati 1/9-4 memiliki nilai bobot per buah dan produktivitas per hektar tertinggi sebesar 934,7 g dan 29,91 ton ha-1 dan toleran terhadap pecah buah dengan kriteria tahan

Cracking fruit is one of the physiological disorders that occur in tomato plants. Cracking fruit can reduce production yields and have a significant impact on marketable fruit losses. This study aims to examine mutant genotypes that are tolerant of fruit breaking and high yielding. This research was conducted in July- November 2019 at the Leuwikopo Experimental Garden, IPB, Dramaga, Bogor, West Java. The experiment was conducted using a Completely Randomized Block Design (RAKL) with one factor, namely the treatment of mutant tomato genotypes with 13 levels. The study was conducted with three replications so that 39 experimental units were obtained. The results showed that the genotype treatment had a significant effect on several characters such as plant height, fruit diameter, fruit length, weight per fruit, fruit weight per plant, and productivity. Genotype M5/990 Kudamati 1/9-4 had the highest weight value per fruit and productivity per hectare of 934.7 g and 29.91 tons ha-1 and was tolerant of fruit breaking with the criteria of resistance.
