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.
