Daya Hasil Galur Harapan Tomat (Solanum lycopersicon L.) di Dataran Rendah

Abstract

The objective of this experiment was to evaluate yield for tomato’s lines (Solanum lycopersicon L.) at lowland. The experiment was conducted at PKHT Experimental Field, Tajur, Bogor in January-April 2013. Experiments used randomized completely block design, single factor and three replications. The factor was genotype that consisted of IPB T3-8-3, IPB T8-5, IPB T30-4-3, IPB T33-1-3, IPB T34-7-10, IPB T43-6-8, IPB T53-3-1, IPB T57-3, IPB T60-2-2, IPB T64-2-3, IPB T65-6, IPB T78-10 genotypes, and three comercial varieties (Intan, Ratna dan Karina) as controls. The results showed that the genotypes significantly affect the overall character. IPB T65-6 and IPB T64-2-3 were genotypes that showed no different performance for fruit width, fruit length, fruit weight, fruit flesh density, total dissolved solid, and vitamin C content compared with comercial varieties as controls. Days of harvesting of IPB T65-6 was earlier than comercial varieties. Agronomically, IPB T65-6 genotype which planted in lowland at Bogor had same yield compared with Ratna and Karina as control. Heritability (high) observed among all characters indicated that genetic factors give more contribute in determining the phenotypic variability of plant. All genotypes had close relationship, shown by the form of seven clusters with 89 % similarity. Factor of yield component was positively correlated with productivity. All genotypes were well adapted in lowland at Bogor.
