Tomat cherry merupakan salah satu komoditas hortikultura multiguna dengan nilai komersial dan bernilai ekonomi tinggi yang berasal dari negara peru dan chilli bagian utara. tomat cherry memiliki ukuran buah lebih kecil dibandingkan tomat umumnya dengan rasa yang lebih manis dan kandungan air yang tinggi. tanaman ini dikenal mudah dibudidayakan karena perawatannya tidak sulit dan pertumbuhannya relatif cepat. genotipe tersebut diantaranya yaitu pc gl, abdya, black cherry, camp joy, pear yellow, white, dan chung, yang berfungsi sebagai sumber informasi dan pengetahuan ilmiah mengenai perbedaan karakter morfofisiologi beberapa genotipe tomat cherry. penelitian ini bertujuan untuk mengetahui karakter morfofisiologi beberapa genotipe tomat cherry pada fase generatif. penelitian dilaksanakan di kebun percobaan fakultas pertanian universitas syiah kuala menggunakan rancangan acak kelompok (rak) nonfaktorial dengan tiga ulangan. parameter yang diamati meliputi karakter morfologi kuantitatif dan kualitatif serta karakter fisiologi tanaman. hasil analisis ragam menunjukkan bahwa genotipe berpengaruh sangat nyata terhadap waktu berbunga, bobot per buah, panjang buah, diameter buah, ketebalan daging buah dan kekerasan buah, berpengaruh nyata terhadap jumlah buah per tanaman dan total padatan terlarut, namun tidak berpengaruh nyata terhadap kandungan vitamin c. secara umum, setiap genotipe menunjukkan karakter morfofisiologi yang berbeda. genotipe abdya memiliki waktu berbunga paling cepat, chung menghasilkan jumlah buah per tanaman terbanyak, camp joy memiliki bobot, diameter buah, dan total padatan terlarut tertinggi, pear yellow memiliki ukuran buah paling panjang, white memiliki ketebalan daging buah tertinggi, sedangkan black cherry menunjukkan tingkat kekerasan buah tertinggi. pengamatan karakter kualitatif juga menunjukkan adanya variasi pada warna buah muda, buah intermediet, buah matang, bentuk buah, bentuk pangkal buah, bentuk ujung buah, dan jumlah rongga buah. hasil penelitian ini menunjukkan adanya keragaman karakter morfofisiologi antar genotipe tomat cherry yang berpotensi dimanfaatkan sebagai sumber plasma nutfah dalam program pemuliaan tanaman untuk menghasilkan varietas tomat cherry unggul sesuai karakter yang diinginkan.

Cherry tomatoes are a multipurpose horticultural commodity with high commercial and economic value originating from Peru and Northern Chile. Cherry tomatoes have smaller fruit sizes compared to regular tomatoes with a sweeter taste and high water content. This plant is known to be easy to cultivate because it is not difficult to care for and grows relatively quickly. The genotypes include PC GL, Abdya, Black Cherry, Camp Joy, Pear Yellow, White, and Chung, which serve as sources of information and scientific knowledge regarding the differences in morphological characteristics of several cherry tomato genotypes. This study aims to determine the morphological characteristics of several cherry tomato genotypes in the generative phase. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Syiah Kuala University using a non-factorial Randomized Block Design (RBD) with three replications. The parameters observed included quantitative and qualitative morphological characters as well as plant physiological characters. The results of the analysis of variance showed that the genotype had a very significant effect on flowering time, weight per fruit, fruit length, fruit diameter, fruit flesh thickness and fruit hardness, had a significant effect on the number of fruits per plant and total soluble solids, but had no significant effect on vitamin C content. In general, each genotype showed different morphophysiological characters. The Abdya genotype had the fastest flowering time, Chung produced the highest number of fruits per plant, Camp Joy had the highest weight, fruit diameter, and total soluble solids, Pear Yellow had the longest fruit size, White had the highest fruit flesh thickness, while Black Cherry showed the highest fruit hardness level. Qualitative character observations also showed variations in the color of young fruit, intermediate fruit, ripe fruit, fruit shape, fruit base shape, fruit tip shape, and number of fruit cavities. The results of this study indicate the diversity of morphophysiological characters among cherry tomato genotypes that have the potential to be used as a source of germplasm in plant breeding programs to produce superior cherry tomato varieties with desired characteristics.
