摘要
The bulk of senna plant components are used to make herbal medications to treat infections and other ailments. Except for grading, more than 80% of dried leaves are exported from India. The current study examined the genetic variability, correlations, and character contributions of 25 senna accessions. The amplitude of the GCV was larger than that of the PCV, showing that the selected factors interact genetically. X1 had substantial and positive connections with X4, X5, X6, X8, X11, and X13, while X2 had significant and positive links with X7, X10, X11, X12, X13, and X14. The characteristic X11 made the largest direct contribution to the X14 attribute. In X1 and X13, the indirect effect was greater. Fresh and dry leaf weight had high heritability and medium GA over the mean, respectively, whereas pod weight had high heritability and GA over the mean, at 93.62 and 94.93%. The mean, heritability, and GA over the mean of genotypes Gen 1, 2, 3, 4, and 25 were selected for high yield in the most economically significant traits. As a result, the senna genotypes mentioned above may be effectively exploited.
