Abstract

Chili (Capsicum annuum L.) is one of the horticultural commodities that have high economic value which is used as vegetables or cooking spices, industrial raw materials, and has export opportunities. The development of superior chili varieties requires a large variety of germplasm that can be used as parents to be crossed with each other to obtain new superior traits. One of the efforts to determine the diversity of plants is to characterize the morphology and production. The purpose of this study was to obtain distinguishing characters among ten genotypes of large chilies, to determine the value of genetic parameter estimators for several genotypes of large chilies and to identify important characters that influence the yield of large chili genotypes. The study was a single factor field experiment in the form of 10 large chili genotypes arranged in a Randomized Completely Block Design (RCBD) with 3 blocks as replication. Genotypes of large chili are: Pilar, Arimbi, Baja, Panex, Forever, Columbus, Gada, Dewa, Rengku, Beautiful. Observation variables are plant height, stem diameter, number of leaves, width of leaves,  leng of leaves, flowering age, harvest age,  fruit length,   fruit weight per plant, fruit diameter, and weight of fruit.. Chili characters that show high genetic diversity are leaf width, while high phenotypic diversity is in fruit weight parameters. High heritability values were found in the characters of flowering age, harvest age, and fruit diameter.

Abstract

This study aimed to determine the resistance and yield of accessionized determinate hybrid tomatoes (F1) against Tomato Yellow Leaf Curl Virus (TYLCV), and to obtain accessions of determinate tomatoes that are resistant to TYLCV and have high yields.This research method used Completely Randomized Design (CRD) to test the resistance of tomato accessions from TYLCV attack. The second stage of the experiment used a Completely Randomized Block Design (CRBD) to test the yield of  tomato accession at the tolerance level forTYLCV resistance. The treatments consisted of 7 F1 tomato hybrids, namely T-26, T-41, T-121, T-122, T-165, T-175, T-187, and 3 control hybrid namely T-90, Liontin and Betavila. The data obtained were analyzed using analysis of variance (ANOVA) then followed by DMRT (Duncan's Multiple Range Test) at a significance level of 5%. The results showed that the control hybrid T-90 was resistant and the T-122 hybrid was moderately resistant to TYLCV (Experiments stages I and II). The seven hybrids tested (T-26, T-41, T-121, T-122, T-165, T-175, and T-187) had the same weight of fruits as the TYLCV resistant control hybrid (T-90). The superior hybrids on the parameters of weight of fruits, weight per fruits, number of fruit, and fruit diameter were T-122 and T-175. Hybrid (F1) which has resistance to TYLCV and high yield is T-122.
