Abstract

In breeding activities, the testing of new varieties for a particular environmentneeds germplasm with high variability and genetic information, including thevalue of heritability estimates. The research was aimed to know the variability and estimate heritability value on 9 genotypes of tomato on organic farming. The research was conducted at Torongrejo village, Junrejo subdistrict, Batu, East Java at the altitude of ± 700 m above sea level. The research used the Randomized Completely Block Design with three replications and 9 genotypes of F5 generation as treatment. Selection was done in organic breeding that specified in applying organic pesticide and fertilizer without any synthetic chemicals. Data of the observation was analyzed to find out the analysis of variance (anova), coefficient of genotypic and phenotypic variances and heritability. The results showed that the number of pieces of good character, the number of total fruit, fruit weight was good, ugly fruit weight, fruit weight and the total weight per piece had high values for the coefficient of genotypic and phenotypic variability. Result of the heritability calculation on characters number of good fruit, good fruit weight and weight per fruit had low values.Keywords: Tomatoes, Genotypic and phenotypic variability, Heritability,Organic farming

Abstract

Red durian plants have the potential to be developed because they have high economic value. Red durian plants are propagated conventionally in two ways, namely through seeds and shoot grafts. Propagation using shoot graft creates a new problem for red durian farmers, namely a decrease in fruit production on the parent plant due to large amounts of scion. One alternative to the propagation of red durian seeds without damaging the parent plant can be done by using tissue culture techniques. The explants used in this study was durian callus. The callus was grown on B5 media treated with a plant growth regulator combination in the form of TDZ consisting of six treatments, namely 0, 0.4, 0.8, 1.2, 1.6 ppm and BA consisting of five treatment, namely 0, 0.3, 0.6, 0.9, 1.2 ppm. This research was conducted to determine the best dose of combination treatment of tidiazuron (TDZ) with BA in the formation of shoots from red durian callus through tissue culture. The results showed that at the age of 6 months after culture, red durian callus had a color change from yellow to green in the TDZ treatment 1.6 ppm + BA 1.2 ppm.
