Abstract

One method to obtain genetic information is the diallel cross analysis. The objective of this study was to eavluate the genetic parameters of six inbred pepper (Capsicum annuum L.) using full diallel crosses. The experiment was conducted at IPB Experiment Field, Cikabayan, Darmaga. The design was randomized complete block design (RCBD) using three replications as blocks. Data from generation F1 and parents were analyzed using the Hayman Method. Results indicated that no epistatic effects were significant for all the traits assessed. Additive genetic effects were larger than the dominant effects for yield per plant, fruit length, and  diameter fruit traits. Dominant genetic effects were larger than the additive effects for fruit weight traits. Narrow-sense and broad-sense heritability were high for all the traits assessed. The character of the yield per plant, fruit weight and fruit diameter shows that there were more dominant genes in the parents. There were more recessive genes in parents for the fruit length character. IPB C7 parent was the most recessive genes containing control characters in the yield per plant. In the new improved varieties of high yielding, IPB C7 could be crossed with IPB C9. Employing individual or mass selection breeding should be successful in developing high-productivity lines in this population.

Abstract

Induction of genetic variant of Artemisia annua L. was conducted through the application of gamma ray irradiation in 2007-2008. The aim was to obtain a plant with high artemisine content > 0.5% and late flowering period of about > 7 month after planting. Tweleve selected genotypes were subsequently examined to gain genetic stability on altitude of 1500, 950, and 540 m asl. The results showed that the plants had shorter flowering age in Cicurug (540 m asl) than that of  in Pacet (950 m asl) and Gunung Putri (1540 m asl). Genotype 8 had the latest age of flowering in the three locations than the other genotypes, however, the growth and biomass were the lowest. Vegetative growth of Artemisia in Pacet and Gunung Putri was better than those in Cicurug. Genotype of 15 in Cicurug and 5A genotype in Gunung Putri and Pacet had higher wet and dry weight than that of two other associates. Based on plant biomass, 5 genotypes from Gunung Putri and Pacet i.e. 1D, 3, 5A, 14, and 15 genotypes were selected, as well as 5 genotypes i.e. 1D, 3, 4, 5A, and 15 genotypes from Cicurug. Analisys on artemisin content successfully obtained 5 selected somaclone lines i.e. 1B, 2, 4, 14, and 3 somaclones.

Abstract

The ability of seed to maintain seed quality during storage is called seed vigor. Accurate method for seed vigor testing of pepper seeds is necessary to accurately determine seed storability during seed distribution. The aim of this research was to determine the best accelerated aging method (AAM) of pepper seed. Freshly harvested seeds of Capsicum annuumL., IPB C9 genotype were used in this study. The experiment used randomized complete block design (RCBD) with three replications. The experimental treatments were seed vigor testing methods i.e. natural deterioration test at room temperature in controlled humidity (RH 90-95%), and four AAM (hot water 60 ºC, methanol 20%, ethanol 20%, and high temperature at 40 ºC). The best method was selected using analysis of variance, coeficient of variance, regresion dan t student analysis. AAM using 20% methanol at periods of 0, 2, 4, 6 and 8 hours was the best method of seed vigor testing for pepper seed. Keywords: accelerated aging, deterioration, ethanol, methanol, high temperature

Abstract

Selection method is one of the most important factors in determining the success of pepper breeding programs. Selection method will be effective if it is supported by a complete knowledge of genetic character inheritance. The aim of this research was to investigate the inheritance patterns to quantitative characters using large pepper (P1 (IPB C5)), curly pepper (P2 (IPB C105)), F1, F1R, BCP, BCP2 and F2. The result showed that dichotomous height, days to harvest and weight per fruit characters were not maternally inherited. The additive-dominant genetic model was the most suitable for dichotomous height character. The additive-dominant with influence of interaction additive-dominant and interaction dominant-dominant genetic model was suitable for days to harvest character. The additive-dominant with influence of interaction additive-additive and interaction dominant-dominant genetic model was suitable for the weight of fruit character. Broad-sense and narrow-sense heritabilities range medium for dichotomous height and weight per fruit characters. Heritability of the days to harvest character was high in a broad-sense but was low in the narrow-sense. Keywords: genetic model, heritability, inheritance

Abstract

Anthracnose is one of the most destructive pepper diseases in Indonesia. Colletotrichum acutatum has been identified as a predominant species in pepper fields of Asian countries including Indonesia. The experiment used completely randomized block design with 2 factors and 4 replications. The first factor was 14 genotypes (c-1,2,3,4,5,7,8,9,15,18,19,28,47, and 49, and the second factor was 4 isolates of C. acutatum (PYK 04, BGR 027, MJK 01, and PSG 01). Each experimental unit used 10 green pepper fruits.  Inoculation methods followed the AVRDC procedure and resistance score followed the modified procedure of Yoon method. Symptoms were evaluated five days after inoculation. Disease incidence was evaluated using Yoon method with slight modifications. The experiments showed that C-15 genotype was more resistant to anthracnose than others; C-8 and C-49 genotypes were recorded as susceptible to anthracnose. Except the three genotypes, all other genotypes were recorded as highly susceptible to anthracnose. Capsaicin content and peroxsidase activities were not correlated with resistance to anthracnose.   Key words:  pepper, resistance, anthracnose, Colletotrichum acutatum

Abstract

The selection of Jatropha curcasfor drought tolerance is one of the key points prior to growing the species extensively on marginal lands. The objective of this study was to determine drought tolerant genotypes based on morphological and physiological characters. The research consisted of two experiments. The first experiment was aimed at determining the moisture content of the media to generate drought stress. The experiment was arranged in a split-plot design with moisture content as the main plot and genotypes as sub-plot. Four level of moisture contents were tested, i.e. 22-23%, 27-28%, 32-33%, and 37-38%. The genotypes tested (9) were Dompu-1, Gunung Tambora, Bima (representing genotypes from dry areas); Aceh Besar, IP-2P, Komering (representing genotypes from wet areas); and IP-1M, Papua, Yogyakarta (representing genotypes from moderately dry areas). The result showed that 22-23% moisture content of the media was suitable for drought tolerance test in Jatropha curcas. The second experiment was screening of genotypes using the suitable media moisture content from first experiment. Twenty three genotypes were screened for drought tolerance under 22-23% media moisture content. The result show that Dompu-2, Indralaya and China were tolerant to drought; Sukabumi-1, Sukabumi-2, Pidi, Lahat, Kupang, Lampung-2, Lampung-3, Sumba, IP-2M, and IP-2A genotypes were moderately tolerant; Curup, Bogor-1, Bogor-2, Bogor-3, Pontianak, Pagar Alam, Palembang, Saweli, Jeneponto, and Medan genotypes were sensitive to drought. Plant height, leaf water content, leaf area and percentage of plant survival can be used as indicators of drought tolerance for seedling selection using a non-destructive method.Keywords: drought tolerance, genotypes, Jatropha curcas, screening
