<p>Chili (Capsicum annuum L.) is an important horticultural crop which possesses high genetic diversity. Their genetic diversity needs to be assessed through molecular marker-based analysis to facilitate chili breeding scheme. The objective of the study was to analyze the genetic diversity of 41 chili genotypes using Simple Sequence Repeat (SSR) markers. Eleven SSR markers were used to amplify all genotypes through PCR technique, visualized on Polyacrylamide Gel Electrophoresis (PAGE). The data were analyzed using NTSYSpc version 2.1 and PowerMarker version 3.25 softwares. Results showed that the average of<br />SSR alleles was 7.9 with a range of 4-11 alleles per marker. All SSR markers showed PIC value >0.5, indicating their suitable use for chili genetic studies. Cluster analysis of 41 genotypes generated three main groups according to coefficient similarity of 77.4%. The genetic clusters appeared as reflection of the genetic background of each genotype. In addition, the SSR markers used can identify potential parent as indicated by the genetic distance between genotypes. The highest genetic diversity (0.698) was demonstrated by combinations of Yuni × Ayesha, Yuni × Ayesha 2, and Yuni × Namira. The estimated genetic diversity produced by SSR markers in this study should be useful as guidance for chili breeders to select suitable parents for new cultivar development for high productivity and resistance to diseases.</p>

“…Chilli pepper is widely grown as a spice crop in the tropical and temperate region, whereas sweet pepper is cultivated as high-value greenhouse crop [4]. Chilli is native to Central and South America, and India is considered as the secondary centre of diversity for C. annuum [5]. The outcrossing in chilli ranges from 7-65% under field conditions, therefore considered as facultative cross-pollinating species [6,7].…”

Chilli leaf curl virus (ChiLCV) is a severe threat to the successful cultivation of the chilli peppers. Besides, the genetics and heterosis for important traits under the influence of ChiLCV infestation is not well studied. Therefore here, were crossed seven genotypes (lines) with high yield and quality attributes with four highly resistant genotypes (testers) in a line (L) × tester (T) mating design to produce 28 F1 hybrids. Parents and their hybrids were evaluated for yield attributes and ChiLCV resistance. All the four testers were symptomless and among seven lines, two were moderately resistant and five were moderately susceptible to the ChiLCV. Among 28 F1 hybrids, 12 showed a moderate resistant reaction, 11 were moderately susceptible and five susceptible to the ChiLCV disease. Based on per se performance, most promising hybrid combinations were L3 × T2, L6 × T1, and L3 × T1 for yield attributes. Whereas the superior crosses for ChiLCV resistance based on heterobeltosis, standard heterosis and specific combining ability test (SCA) effects were L6 × T1 and L7 × T3. Lines and testers showed significant differences for all the characters except for the plant height. The general combining ability (GCA) effects for testers were significant for all the traits except for days to first harvest. The ratio of σ2GCA/σ2SCA indicated the predominance of non-additive gene effects in the inheritance of traits studied in this experiment. The contribution of lines was more compared to testers for all the characters except for primary branches plant-1. Overall, this study provides valuable information regarding the genetics and heterosis in chilli with respect to ChiLCV infestation

“…is an economically important vegetable crop belonging to Solanaceae family. It was introduced from the West Indies into Europe in 1493 following the first voyage of Christopher Columbus, after which they were rapidly distributed to Africa and Asia (Zhang et al, 2016). Species belonging to the genus Capsicum are diploid and have 2n = 2x = 24 chromosomes, meanwhile some others have 2n = 2x = 26 chromosomes (Pozzobon et al, 2005).…”

Sweet pepper (Capsicum annuum L.) is considered as the most important vegetable crop worldwide. Association mapping based on linkage disequilibrium is a capable tool to identify genes controlling plant agrobiological characteristics. In this study, an association panel consisting of 29 indigenous sweet pepper accessions were collected from several geographical regions of Iran. The panel was evaluated phenotypically for sixteen fruit as well as plant architecture traits across two locations under field conditions. In molecular experiment, 10 inter simple sequence repeat (ISSR) markers were used for genomic fingerprinting of accessions. Results revealed abundant phenotypic variations within this germplasm and a total of 65 markers ranging from 3 to 10 per primer were identified in all accessions. Model-based structure analysis revealed two subpopulations. Out of 29 native sweet pepper accessions studied, 93.1% belonged to one of the two identified subpopulations and 6.9% showed mixed structure. A total of 17 marker-trait associations were detected based on a mixed linear model, of which one (UBC825-1) was found as a common marker for some agrobiological characters. The favourable 17 marker loci can be utilized in plant architecture breeding programmes according to specific breeding objectives.
