“…Correlation study for fruit yield per plant showed positive and highly significant correlation with nine traits, which is consistent with the reports of Mena et al (2018) , Devi et al (2018) and Ozukum et al (2019) in ghost pepper. The correlation study for capsaicin content was also consistent with the reports of Datta & Jana (2010) and Vaishnavi, Khanm & Bhoomika (2017) in different Capsicum species. Genotypic path study for fruit yield per plant has been studied because the results at phenotypic level may not provide appropriate results of direct and indirect relation of the component traits ( Negi & Sharma, 2019 ).…”

“…This formation of many individual clusters based on morphological characterization indicates the presence of sufficient genetic variability among them. In C. annum , Ajjappalavara (2009) , Kumari et al (2010) and Datta & Jana (2011) also observed formation of large number of clusters, indicating the presence of wide variability in the studied material. According to Patel et al (2017) genotypes from highly divergent clusters should be used for the development of high-yielding varieties.…”

Capsicum chinense Jacq. (ghost pepper), a naturally occurring chili species of Northeast India is known throughout the world for its high pungency and a pleasant aroma. The economic importance is due to the high capsaicinoid levels, the main source for pharmaceutical industries. The present study focused on identifying important traits necessary for increasing the yield and pungency of ghost pepper and to determine the parameters for the selection of superior genotypes. A total of 120 genotypes with more than 1.2% capsaicin content (>1,92,000 Scoville Heat Unit, w/w on dry weight basis) collected from different northeast Indian regions were subjected to variability, divergence and correlation studies. Levene’s homogeneity test of variance studied for three environments did not show significant deviation and so homogeneity of variance was reasonably met for analysis of variance study. Genotypic and phenotypic coefficient of variation was highest for fruit yield per plant (33.702, 36.200, respectively), followed by number of fruits per plant (29.583, 33.014, respectively) and capsaicin content (25.283, 26.362, respectively). The trait number of fruits per plant had maximum direct contribution to fruit yield per plant and the trait fruit yield per plant towards capsaicin content in the correlation study. High heritability with high genetic advance, which is the most favored selection criteria was observed for fruit yield per plant, number of fruits per plant, capsaicin content, fruit length and fruit girth. The genetic divergence study partitioned the genotypes into 20 clusters, where fruit yield per plant contributed maximum towards total divergence. Principal components analysis (PCA) studied to determine the largest contributor of variation showed 73.48% of the total variability, of which the PC1 and PC2 contributed 34.59% and 16.81% respectively.

“…These compounds vary in quantity among the genotypes, thus prior knowledge on phenotypic and genotypic variance is crucial for the selection of best parents for the chilli breeding programmes that aim to improve the fruit quality. Nonetheless, another major focus of the chilli breeders is to achieve the high fruit yield which is a complex hereditary character being influenced by various other traits [4]. The genetically different genotypes have a great significance to be utilized for the breeding programmes [5].…”

Capsicum annuum L. is an indispensable spice cum vegetable crop cultivated worldwide for its edible fruit. The current research is majorly focused on the development of improved chilli varieties to achieve high fruit yield and quality to meet the rapidly growing market demands. Therefore, the screening of the chilli landraces and local cultivars for the genetic variation would provide best parents for the chilli crop improvement. Most of the recent chilli breeding programmes involve the assessment of genetic variation among the genotypes by the estimation of important genetic variation parameters such as phenotypic and genotypic coefficients of variation, heritability and genetic advance, gene flow, and cluster analysis. Correlation and path coefficient analysis was also applied to evaluate the progeny to understand the association between desired traits. The popular DNA-based molecular marker system, simple sequence repeat, is predominantly applied to understand the genetic variation as well as to select the desired progeny. In this current review, we discussed such recent research reports on chilli crop improvement for high fruit yield and quality, highlighted the recent major achievements and provided the important information for the chilli breeders. We hope this current review would shed light on recent developments in chilli crop improvement and help chilli breeders for their future breeding programmes.
