Abstract

The purpose of this study was to estimate the inheritance pattern of qualitative character traits from the F2 population of the Bara x Ungara and Dewata cross. The study was conducted in the experimental garden of Unhas, Tamalanrea sub-district, Makassar, South Sulawesi. The quantitative character traits observed consisted of four characters, namely, the color of the flower corolla, the coloring of the immature fruit, the branching habit, and the nodal color. The results showed that the population of F2 crosses showed a purplish-green color (34) as the dominant color in immature fruits. Crosses with the Ungara variety exhibited a significant contribution to the color in the immature fruit. The nodal color characters is closely related to the duplication interaction pattern between alleles at different loci

Abstract

The shifting of tomatoes cultivation from upland to lowland led to a significant decrease of tomatoes production, particularly on tomatoes varieties which are not able to adapt to lowland. Genotypes selection based on appropriate selection criteria is the most effective method to obtain tomatoes genotypes with high production in the lowland. The aim of this study was to determine appropriate selection criteria in the lowland based on high heritability value, high phenotype and genotype  correlation to production component, and character relationship closeness with production component through path analysis. This study used a randomized block design with three replications. Selection criteria was chosen based on high heritability value, significant correlations in phenotype and genotype and its high direct impact on fruit weight per plant which were the number of fruits per plant and weight per fruit characters

Abstract

Plant regeneration through invitro culture is strongly influenced by the use of growth regulators. BAP is a class of cytokinins that affect cell division which is very well used to stimulate plant growth. The aim of the study was to determine the effect of BAP concentration on the regeneration of various in vitro mutant taro. The study was carried out at the Plant Tissue Culture Laboratory,  Faculty of Agriculture, Hasanuddin University, Makassar. The method used was factorial completely randomized design with 2 factors as the environmental design. The first factor was the BAP concentrations of 0.0 mg/L, 1.0 mg/L, 1.5 mg/L, 2.0 mg/L and 2.5 mg/L. The second factor was mutant plants consisting of control plants (diploid), mutant 1 (Putative-Tetraploid), mutant 2 (Mixoploid), mutant 3 (Mixoploid), and mutant 4 (Putative-Tetraploid). The results showed that the best regeneration was obtained by BAP concentration of 0 mg/L with control plants on the parameters of root length (2.41 cm), number of roots (11.66 pieces) and plantlet formation rate (13 days). The BAP concentration of 1 mg/L was shown by mutant plant 1 on the parameters of the number of shoots (26 pieces) and number of leaves (16 pieces). BAP concentration of 0 mg/L in mutant 4 had a shoot height of 1.83 cm. The results of ploidy flow cytometry analysis of mutant plants with Putative-Tetraploid parental traits after regeneration resulted in detectable diploid chromosomes that were different from the parent types in all BAP concentration treatments
