Pendugaan Daya Gabung dan Heritabilitas Komponen Hasil Tomat pada Persilangan Dialel Penuh
ABSTRACT Hybridization is one of plant breeding techniques to obtain high yielding varieties. Combining ability and heritability information are needed for evaluating hybrids’ performance.

The experiment used a randomized complete block design (RCBD) with three replications. IPBT1, IPBT13 and IPBT84 had a good general combining ability (GCA) for weight per fruit, fruit size and weight of fruit per plant.

IPBT13 × IPBT1 hybrid showed a high and positive specific combining ability (SCA) values for all characters, therefore it can be used for hybrid variety. The highest broad and narrow sense heritability was obtained for fruit size, meanwhile the lowest was obtained for weight of fruit per plant. Weight per fruit, fruit size and weight of fruit per plant characters were influenced by additive and dominant gene effects, whereas number of fruit per plant was influenced by additive gene effects.
