Morphological Characterization of 10 Hot Pepper Genotipes in Low Altitude Location

Abstract

Development of high yielding and superior cultivars requires information on characteristic of germplasm will be used. Ten curly-type hot pepper genotypes was grown in a completely randomized design with three replication in a low altitude land to determine their morphological characters and to evaluate genetic relationship among them based on their morphological similarities. The study was conducted in September 2015 until January 2016 in Medan Baru experimental station of Faculty of Agriculture, 15 m above sea level. Observation was conducted on both quantitative and qualitative characters. The results showed that there were not significantly diferent (?=5%) for plant habitus, leaf shape, leaf tip, leaf edge, leaf shape and seed shape. Whereas for quantitative variables of stem diameter, number of fruits per plants and fruit length were significantly different, while for the other variables were not. Cluster analysis with phylogenetic trees in 58% similarity coefficient resulted that the genotypes grouped in to six groups. Group I consisted of genotype LPK and Ferosa, group II Mario, group III was genotype Laris, group IV consisted of genotype Kopay and Romario, group V KH and L Curup, and group VI included genotype Bogota and Sempurna. The Kopay and Romario genotypes have the closest relationship level of 73%, while Local Payakumbuh and Lokal Curup have the farrest relationship with the coefficient of 35%. From the results of the study it can be concluded that Local Payakumbuh and Local genotypes Curup can be used as parents with the highest probability to have high transgresive segregation or highest hybrid vigor.

Inheritance Pattern of Qualitative Character Traits in F2 Population of the Bara x Ungara and Dewata x Unggara Crosses

“…Based on the results above, the inheritance pattern of immature fruit color shows a high complexity. It is also in line with the report of Herison C., E. Surmaini, Rustikawati, & Yulian, (2018). As a qualitative character, this character has quite a lot of groups.…”

“…It is characterized by purple leaves, stems, and fruit. According to Herison, C., E. Surmaini, Rustikawati, & Yulian (2018), Tang, B., L. Li, Z. Hu, Y. Chen, T. Tan, Y. Jia, Q. Xie, & G. Chen (2020), and Huang Y., X. Wang, W. Miao, H. Suo, C. Fu, M. Chen, X. Zhaoand, & L. Ou (2021), the purple color on the fruit indicates a high anthocyanin level, so the Ungara variety is good to be used as a biofortification plant. This can be corrected by crossing commercial varieties such as Bara and Dewata.…”

Uji Ketahanan Anggrek Hibrida Phalaenopsis terhadap Penyakit Busuk Lunak yang Disebabkan oleh Dickeya dadantii

“…gangguan metabolisme akibat aktivitas patogen secara fisiologis lebih rendah yang berpengaruh pada penurunan aktivitas peroksidasenya (Herison et al, 2007). Ketebalan dan kadar air daun diduga berpengaruh juga terhadap luas gejala serangan patogen pada tanaman anggrek hibrida Phalaenopsis.…”

Effect of various LED light on the growth and reproductive of in vitro-derived Indonesian chili pepper (Capsicum annum) Kopay and Laris varieties

“…Chili (Capsicum annuum L.) is one of horticultural crops that is in high demand in Indonesia. Chili has a favorable economic outlook, because of increasing demand of household needs, food industry and pharmaceuticals in harmony with the increase of population (1). Chili can be consumed in the form of fresh fruit, or dry as a cooking spice and also as an industrial raw material for the food, poultry feed and pharmaceutical industries.…”
