Abstract:
In the Indian economy the marigold flower has a key role because it is an essential landscaping crop and economically important loose flower. The wide uses of marigold depend on the variable performance of different genotypes. The evaluation of the performance of the different marigold genotypes was carried out on a set thirteen traits. The highest plant height at 30, 60 and 90 DAT was reported by marigold genotype Pusa Arpita. The lowest plant height observed in CGFM-2 at 30 DAT while the genotype CGFM-1 reported lowest plant height at 60 and 90 DAT. At 60 and 90 DAT, the highest plant spread of east-west and north-south was recorded by CGFM-3 whereas, the lowest reported by Chaindani Gainda and CGWM-1 at 60 and 90 DAT respectively. The highest primary branches per plant at 30 and 60 DAT reported by genotype CGFM-3 while at 90 DAT, Pusa Arpita showed maximum primary branches per plant. The highest number of secondary branches per plant was observed in genotype CGFM-1 and CGFM-3 at 60 and 90 DAT respectively. At 30 and 60 DAT number of leaves per plant was highest in genotype CGWM-1 but at 90 DAT it was present in Pusa Arpita. The lowest days required for first bud appearance and days for 50% reported by genotype CGWM-1 and Chaindani Gainda respectively. The significantly highest number of flowers per plant and flower diameter was observed in the genotype CGFM-1 and CGWM-1 respectively. The highest yield of flower per plant and per hectare was witnessed in the genotype CGFM-1. It has been observed that the value of high GCV, PCV and heritability along with high genetic advance as percentage of mean were recorded for the traits such as plant height (cm), number of secondary branches per plant, number of leaves per plant, days to first bud appearance, days to 50% flowering, number of flowers per plant, flower diameter (cm), flower yield/ plant (g) and flower yield (q/ha). It has been observed that the greater value of GCV and PCV was present for a trait that much affected by environmental factors. It has been observed that the higher genetic advance along with higher heritability can be most applicable for effective improvement of any kind of traits through selection in simple manner.
