“…Menurut Agastya et al (2017) penurunan produksi sebagian besar dipengaruhi oleh hama, penyakit tanaman, dan gulma. Selain itu, Dalimunthe et al (2015) dan Dewi et al (2016) menyatakan bahwa kendala yang menyebabkan menurunnya produksi cabai rawit yaitu hama dan penyakit.…”

Improvement of chilli’s quantitative traits requires several stages of breeding program, one of these is selection stage. The objective of this study was to obtain the information concerning the means and ranges of some quantitative characters, inbreeding depression, heritability estimates, and response to selection from six generations derived from crossing two parents of chili peppers. Materials used were IPB C160 (female), IPB C291 (male) as parents, F2, F3, F4, F5, and F6 derived from crossing of these parents with a total number of 630 plants. Results from this study showed that the mean valuesbetween the generations F2 to F6 showed an increase in the observed character except of harvesting time. The highest value of inbreeding depression for harvest time, weight per fruit, and fruit length was found in F5 generation. The highest value of inbreeding depression for fruit weight per plant, number of fruit per plant, and fruit weight was found in F6 generation, and for fruit diameter was found in F4 generation. The narrow-sense heritability estimates were classified into low to moderate criteria. In general, declined responses to selection for quantitative characters in the six generations of chili were observed.Keywords: advance selection, heritability, inbreeding depression, means value

“…Heterosis hibrida ideal yang dapat dieksplorasi adalah yang memiliki nilai DGK tinggi dengan pengaruh DGU tinggi pada kedua atau salah satu tetuanya. Hal ini setara dengan penelitian pada pada jagung hibrida (Azrai et al 2014), cabai (Dalimunthe et al 2015), dan timun (Wiguna et al 2013).…”

The combining ability value provides information on the yield potential of parental lines on their F 1 hybrids. The objectives of the research were to study the combining ability of line (CMS/A) and tester (Restorer/R) on the form of hybrid, and to evaluate the performances of the hybrids. The research was conducted from November 2014 to February 2015 at Indonesian Center for Rice Research research station, in Sukamandi. Mating design and analysis were applied by using lines x tester design. Thirty hybrids and their parental lines were planted in the field using randomized complete block design with three replications. Male sterile line IR58025A shared the highest value of general combining ability (GMJ) for the characters of grain yield and for number of filled grain per panicle, while GMJ 14A was the best combiner for maturity, and seed set. Among the testers, PK 12 line was the best general combiner for maturity and seed set, while BP 11 was the best general combiner for number of filled grain per panicle. The experimental hybrids rice with high specific combining ability for grain yield were GMJ 14A/R 32 (Kalinga), GMJ 15A/R 32 (Gambiaca), and GMJ 13A/R3 (WA). The experimental hybrids showed 10% standard heterosis when compared to Maro (hybrid) and Ciherang (inbred) varieties, with the grain yielded of 12.4; 10.7 and 10.2 t/ha, respectively.

This study aims to determine the diversity of qualitative and quantitative characters of hybridized chili plants The research was carried out at the Screen House of the Faculty of Agriculture, Syiah Kuala University, Banda Aceh from April to December 2019. The genotypes used in this research were hybridized chili (IPB C2, IPB C10, F1 C10×C2, BCP1 (C10×C2)×C10, BCP2 (C10×C2)×C2, F2(C10×C2). The Completely Randomized Non Factorial Design was used only for the placement of plant in the field. Data analysis was performed by calculating the average value, variance, and standard deviation. The results showed that the quantitative characters that could be made as selection characters were plant height, and number of fruit per plant. There is diversity in the qualitative character, the shape of lancet leaves are dominant to the shape of oval leaves. This can be seen in IPB C2, F1 (C10 × C2), BCP1 (C10 × C2) × C10 has the shape of a lancet leaf. On IPB C10 has an oval leaf shape then for BCP2 (C10 × C2) × C2 dan F2 (C10 × C2) have the same shape as oval and lancet leaves. Diversity is also seen in the position of flowers there are three types, namely upright, semi-erect and dangling, but all genotypes have the shape of elongate fruit. The result of this research showed the quantitative characters that can be used as selection characters were plant height and fruit number per plant.
