Abstrak:Â Â Â Â Â Â Percobaan ini bertujuan mengevaluasi metode pengusangan cepat methanol 20% selama 0, 2, 4, 6 dan 8 jam pada benih cabai hibrida, non hibrida, lokal, introduksi, rawit dan besar yang diproduksi pada tahun 2009 dan 2010. Jumlah genotipe benih non hibrida 4 (2009) dan 4 (2010). Jumlah genotipe benih hibrida 10 (2009) dan 8 (2010). Analisis data dilakukan dengan analisis sudut kemiringan garis regressi yang merupakan sudutÂ perbandingan ordinat dan axis. Rekapitulasi hasil evaluasi vigor daya simpan benih cabai menunjukkan bahwa tidak ada perbedaan antara benih produksi tahun 2009 dan 2010, dan benih cabai hibrida danÂ non hibrida, serta benih cabai lokal dan introduksi. Perbedaan terdapat pada benih cabai rawit dan besar dan laju penurunannya cabai besar lebih cepat dibandingkan benih cabai rawit.Â Hal ini terjadi juga pada tolok ukur daya hantar listrik yang merupakan tolok ukur terbaik untuk vigor daya simpan benih. Hal ini menunjukkan besarnya pengaruh lingkungan terhadap vigor daya simpan benih cabai.Â Kata kunci: deteriorasi alami, laju kemiringan vigor daya simpan benih cabai.Â AbstractÂ Â Â The experiment was designed to evaluate the accelerated aging method with 20% methanol for 0, 2, 4, 6 and 8 hours which is the first stage of the experimental results at several pepper seed genotypes including hybrid seeds, non hybrid, local, introduction, pepper and great pepper produced in 2009 and 2010. The seeds used are non-hybrid seed as much as 4 genotype seed production in 2009 and 4 genotype seed production in 2010. Hybrid seeds used were 10 genotypes of production in 2009 and 8 genotypes of production in 2010. Data analysis done is the analysis of the slope angle of regression line slope which is resulting from the comparison of the ordinate and the axis. Recapitulation of the pepper seeds vigor storage evaluation results showed that the seed production in 2009 and 2010 there was no difference between the hybrid and non-hybrid pepper seeds and the local and introduction pepper seeds, but there are consistent differences between great chili and chili pepper seeds, the rate of decline of the great chili is greater than the chili pepper. This shows the magnitude of environmental influences on seed pepper seeds vigor storage. Exclusively in electrical conductivity benchmark, which is one of the pepper seeds vigor storage best benchmark shows that the rate of decline in seed vigor between the hybrid and non hybrid seeds and the local and introduction pepper seeds..Â Key words: natural deterioration, the rate of decline seed pepper vigor test in relation Â to storability

The objectives of this study were to compare nonparametric stability measures, and to identify promising high yield and stability of chili pepper (Capsicum annuum L.) genotypes in eight environments. In every environment, a Randomized Complete Block Design was used with three replications. The method of Nassar and Huehn, Kang, Fox, and Thennarasu was used to analyze the stability and high yield. Spearman’s correlation and Principal Component analysis distinguishes the methods based on two different concepts of stability: the static (biological) and dynamic (agronomic) concepts. The top method was found to be the dynamic stability. Meanwhile, the methods of Si1, Si2, Si3, Si6, Npi1, NPi2, NPi3 and NPi4 were found to be the static stability. Based on the ranking frequency stability of the nonparametric method, the genotypes with the highest frequency of static stability ranking were genotypes IPB002003, IPB002046, IPB009019 and Tit Super, whereas IPB009002 and Tombak were categorized as those of dynamic stability. Genotype IPB120005 and IPB019015 were less adaptable in the multiple environments tested. It shows that the genotypes were specific in certain environments. IPB120005 had high yield and specific location in Boyolali in dry season and IPB019015 genotype was specific in Bogor in wet season. Keywords: chili pepper, nonparametric stability, high yield, dynamic stablility

One of the problems of horticultural seeds is the lack of quality of seeds. This experiment aims to evaluate the methods of rapidly pouring hybrid, non-hybrid, local, introduced cayenne pepper seeds and large quantities produced in 2014 and 2016. Non-hybrid seeds were 4 production genotypes in 2014 and 4 in 2016. The hybrid seeds used were 10 production genotypes in 2014 and 8 in 2016. The data analysis used is an analysis of the regression line's angle of inclination, which is the angle resulting from the comparison of the ordinate and abscissa. Based on the results of rapid pouring tests using 20% methanol for 0, 2-, 4-, 6- and 8-hour information, the storability of seeds produced in 2014 was better and higher than in 2016 Therefore, hybrid chili seeds and non-hybrid chili seeds have the same seed storability vigor, as well as between local vs introduced chili seed also large chili seed vs cayenne pepper.

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 Arif, Abdullah Bin; Sujiprihati, Sriani; Syukur, Muhamad

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

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

ABSTRACTThe objectives of this study were to evaluate several chili pepper hybrids whith high yielding character and stable at six environments based on some non-parametric stability analyses, and to study the correlation among the stability of non-parametric methods. The hybrid of chili pepper (7 candidates varieties and 5 commercial hybrid cultivars) were grown in a randomized complete block design with 3 replications in 6 different environments. Ten nonparametric stability methods were used to identify the stable genotypes. According to the SI(3), RS, NPi(1), NPi(2), NPi(3) and NPi(4) stability parameters, Imperial was the most stable hybrid. According to the SI(1), SI(2) and TOP stability parameters and yield, IPB CH3 was the most stable hybrid. In this study, the high TOP values were associated with the yield. Nonetheless, the results of the other non parametric (SI(6), NPi(3) and NPi(4)) were negatively correlated to the yield. The results also revealed that based on the non parametric stability test, the results could be classified into 2 groups, according to the agronomic and biological stabilities. Keywords: chili pepper, environment, non-parametric stability, yield
