Genetic relationships between thirteen genotypes of chilli and paprika collected from different places of India were analyzed using twelve RAPD and nine SSR primers. Clustering based on the generated markers was conducted using NTSYS software's. The RAPD primers produced a total of 78 bands of which 65 were polymorphic with a mean of 5.41 polymorphic bands per primer while the SSR primers produced 28 SSR loci with a mean of 3.22 alleles per SSR locus. The similarity index matrix ranged from 0.36 to 0.91 (RAPD) and 0.117 to 0.9 (SSR) with mean of 0.62 and 0.39 respectively. Polymorphic Information Content (PIC) values of the SSR primers ranged from 0.00 to 0.75 with an average value of 0.546. The resulting RAPD and SSR dendrograms separated the cultivars with small and erect fruit position from the large and medium fruited cultivars with declining fruit position. Both RAPD and SSR markers showed genetic variability in the studied pepper genotypes and they are powerful tools for estimating genetic similarities and diversity.
The present investigation was conducted to find the correlation and path-coefficient analysis for yield and yield contributing characters in Ramnad Mundu chilli (Capsicum annuum L.) during Kharif 2018-19. The experiment was conducted on Forty-seven Mundu chilli genotypes for 15 characters, which was laid out in Randomized Complete Block Design with two replications. From correlation study dry fruit yield per plant showed highly positive correlation with number of fruits per plant (0.971 G, 0.894 P), ripened fruit yield per plant (0.991 G, 0.949 P), number of seeds per fruits (0.383 G, 0.32 P), 1000 seed weight (0.369 G, 0.332 P), capsaicin % (0.302 G, 0.256 P) and number of primary branches per plant (0.267 G, 0.251 P) at both genotypic and phenotypic level. Path-coefficient analysis of different characters contributing towards the highest positive direct effect via number of fruits per plant (0.973), ripened fruit yield per plant (0.991), no. of seeds per fruit (0.383), 1000 seed weight (0.364), capsaicin % (0.302) and number of primary branches per plant (0.267). Hence, direct selection based on these characters would be effective in crop improvement through plant breeding in Mundu chilli.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
