“…These results are superior to those reported by López Arcos et al [36], but lower than those reported by López-Gómez et al [37]. The differences observed in some of the evaluated characteristics are attributed to the origin and genetics of the materials, characteristics that could be improved through selection and inbreeding [31], although the tested environment also influences in the phenotypic characteristics observed [30]. The variability in agronomic behavior between genotypes could guide the selection of materials with the best phenotypic characteristics and include them in genetic improvement programs, creating varieties adapted to new agroclimatic conditions or specific environments [3,38], since the previously described C. chinenese characters are generally highly heritable [39,40].…”

“…It should be noted that the mean yields of the evaluated genotypes coincide with those reported by Loatournerie et al [30] in genotypes evaluated in Conkal, Yucatán in 2009. The number of fruits per plant (Figure 1B) in the HNC-5 and HNC-6 genotypes also stood out, as well as the HNC-3 and HNC-2 genotypes, which are selections of the Jaguar variety, a character that could be improved through selection and hybridization [31].…”

The genetic improvement program of the Seed Technology Training and Development Center works on the agronomic characterization and the content of bioactive compounds in eight genotypes of habanero pepper. The objective is to select genotypes with good agronomic performance that allow the generation of inbred lines to obtain hybrids. In this study, the agronomic performance and the content of bioactive compounds (capsaicinoids, polyphenols, and antioxidant capacity) were evaluated in eight genotypes of habanero pepper grown in the southeast of Coahuila, Mexico, identified as HNC-1, HNC-2, HNC-3, HNC-4, HNC-5, HNC-6, HNC-7, and HCC-8. The plants were grown in a greenhouse for 127 days, under a completely randomized design with four replications each. The results revealed that the yield (g∙plant−1) and number of fruits per plant did not show significant differences between genotypes. However, for the fruit length, the genotypes HCC-8, HNC-7, HNC-6, and HNC-5 stood out with over 40 mm, while in equatorial diameter of the fruit, HCC-8, HNC-4, and HNC-2 stood out with 26.45, 26.46, and 25.12 mm, respectively. The results of the chemical analyses allowed us to identify that HNC-5 and HNC-6 had the highest capsaicin concentration (931.38 and 959.77 mg∙kg−1), dihydrocapsaicin (434.95 and 445.89 mg∙kg−1), Scoville Heat Units greater than 210,000, total phenols (67.54 and 71.15 mg/100 g) and total flavonoids (34.21 and 38.29 mg/100 g), respectively. The HNC-1 and HNC-6 genotypes had the highest carotenoids concentration with 103.96 and 105.07 mg/100 g, and HCC-8 registered the highest anthocyanin content with 22.08 mg C3GE/100 g. The antioxidant capacities showed significant differences (p ≤ 0.05) between genotypes, with a range of 43.22 to 110.39 µmol TE/100 g, 72.37 to 186.56 µmol TE/100 g, and 191.41 to 244.98 µmol TE/100 g for the tests of DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2′azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)), and FRAP (ferric reducing antioxidant power). The results of this research will be used to select habanero pepper genotypes that can be used in genetic improvement programs to increase the productive potential and the content of bioactive compounds in the fruits to expand their applications in the food industry.

“…The significant differences ( p ≤ 0.05) found for each agronomic variable demonstrate the wide variability of the investigated habanero pepper material. Some authors (Martínez‐Martínez et al, 2014; Nandadevi & Hosamani, 2003; Pech‐May et al, 2010) reported all similar values for C. annuum .…”

“…Almost all genetic studies on this genus have been conducted on C. annuum , with a few exceptions on C. chinense . In these species, high levels of heterosis were found in yield, fruits' qualitative and quantitative traits, vitamin C and capsaicinoids contents, and pathogens' resistance (Pech‐May et al, 2010; Sousa & Maluf, 2003; Wani et al, 2003; Zewdie et al, 2000).…”

The objective of this work was to obtain high‐yielding F1 hybrids of the habanero pepper, using 10 outstanding parents in a line‐tester genetic design. General combinatorial ability and specific combinatorial ability were evaluated in the parents' and the hybrids F1 obtained, respectively. Heterosis was determined in the 18 hybrids obtained. The technique of HPLC was used to evaluate the capsaicin content in the fruit of 10 parents and 18 hybrids of habanero pepper. The DNA profiles were analysed as part of the characterization of the germplasm of the species conserved at the CICY. Furthermore, the molecular variation of the genotypes under investigation was assessed using eight SSR and nine ISSR markers. The results showed the presence of substantial morphoagronomic and molecular variability among the habanero pepper genotypes evaluated. Genetic similarities of 83%–93% between parents and 76%–94% between hybrids were found. The most productive hybrids were H8, H10 and H19 with 3.13 to 4.29 kg/plant, respectively, these came from crosses where RNJ‐04 (P26) as the male parent and the hybrid H60 (4.92 kg/plant) that comes from the male parent RES‐08 (P30). Likewise, the H7 hybrid had the highest capsaicin content (128.41 mg/g dry weight, 960,687.00 SHU). Hybrids H43 with 114.39 mg/g DW and 90,444.30 SHU, and H51 with 11.61 mg/g DW and 934,745.07 SHU respectively, also stood out.

Solanum phureja is one of the most important crops for farmer economy in Colombia, and Phytophthora infestans is considered its main limiting disease. This pathogen is managed using chemical products, generating high production costs as well as environmental pollution. The use of resistant varieties is a strategy that is currently well positioned for the control of this disease, leaving the task of identifying superior parentals to plant breeders. Moreover, the analysis of general and specific combinatorial aptitudes of potential parental genotypes gains importance. The aim of this study was to establish the general and specific combinatorial aptitudes of five elite parental cultivars. For this, 979 clones were assessed. General combinatorial aptitude results show statistically significant differences for the Paola, Primavera and Ocarina parentals. On the other hand, the specific combinatorial analysis allowed concluding that the combinations Ocarina×Violeta and Primavera×Galeras contain non-additive effects involved in inheritance. Resumen Solanum phureja es uno de los cultivos más importantes en la economía campesina colombiana. Phytophthora infestans es considerada la principal enfermedad del cultivo. Se controla usando productos químicos, generando altos costos de producción y contaminación ambiental. El uso de variedades resistentes es una estrategia bien posicionada para el control de la enfermedad, dejando la tarea de identificar progenitores superiores a los fitomejoradores, recobrando importancia el análisis de la aptitud combinatoria general y específica de los genotipos potencialmente parentales. El objetivo de este estudio fue determinar la aptitud combinatoria general y específica de cinco parentales élite de S. phureja. Para esto, se evaluaron 979 clones. Los resultados de la aptitud combinatoria general muestran diferencias estadísticamente significativas para los progenitores Paola, Primavera y Ocarina. Por otro lado, el análisis de la aptitud combinatoria específica permitió concluir que las combinaciones Ocarina×Violeta y Primavera×Galeras contienen efectos no aditivos involucrados en la herencia.
