Daya Hasil Tomat Hibrida (F1) di Dataran Medium

Ety Purwti

Abstract


ABSTRAK. Penelitian dilaksanakan pada bulan Juli sampai November 2006, di dataran medium Banyuresmi,
Kabupaten Garut pada jenis tanah Latosol dengan ketinggian 550 m dpl. Tujuan penelitian ialah mengevaluasi 16
genotip tomat hibrida (F1). Materi terdiri atas 16 genotip hibrida, 11 genotip di antaranya berasal dari Balai Penelitian
Tanaman Sayuran. Rancangan penelitian menggunakan acak kelompok dengan 2 ulangan dan 20 tanaman/plot. Hasil
penelitian menunjukkan bahwa genotip IVEGRI 06-05 mencapai hasil tertinggi (56,6 t/ha) tetapi tidak berbeda nyata
jika dibandingkan dengan varietas Marta (49,25 t/ha) sebagai kontrol, yang merupakan varietas tomat terbanyak
ditanam oleh petani di daerah Garut. Produksi terendah dicapai oleh genotip IVEGRI 06-01 (40,10 t/ha) dan Blts
05-08 (40,0 t/ha) berbeda nyata jika dibandingkan dengan genotip IVEGRI 06-02, 06-03, 06-05, varietas Idola, dan
Spirit. Kekerasan buah berkisar dari sangat keras (nilai 3,3) sampai agak lunak (nilai 4,5), meskipun demikian buah
yang paling keras (nilai 3,3) ialah genotip IVEGRI 06-01 dan varietas Marta. Demikian juga daya tahan simpan
buah kedua genotip ini adalah yang paling lama (24 hari).

ABSTRACT. Purwati, E. 2009. Yield Potential of Tomato F1 Hybrid in Medium Land. Sixteen hybrids of tomato
genotypes (F1) were tested, and 11 out of them were hybrid genotypes from Indonesian Vegetable Research Institute
(IVEGRI). The research was conducted in Banyuresmi, Garut District, West Java, at Latosol soil type with an altitude
of 550 m asl., from July to November 2006. Randomized complete block design with 2 replications and 20 plants per
plot were used for field evaluation. The results indicated that IVEGRI 06-05 genotype gave the highest yield (56.60
t/ha) but it was not significantly different to Marta variety (49.25 t/ha) as control. The lowest yields were shown by
both IVEGRI 06-01 (40.10 t/ha) and Blts 05-08 (40.0 t/ha), which were significantly different with IVEGRI 06-02,
06-03, 06-05, Idola, and Spirit. In general fruit firmness ranges from hard to soft (value 3.3 – 4.5). However IVEGRI
06-01 genotype and Marta’s variety indicated the highest hardness (value 3.3) and the longest selflife (24 days).
