Abstract:

The association and path analysis between nine different growth and flowering characters towards yield per plant were studied in ten bachelor’s button (Gomphrena globosa L.) genotypes viz., AGS-1, AGS-5, AGS-6, AGS-7, AGS-8, AGS-9, AGS-10, AGS-13, AGS-14 and AGS-15. The results indicated that that flower yield per plant had the positive and highly significant association with number of flowers per plant (0.772), test weight of 50 flowers (0.701), duration of flowering (0.626), number of primary branches per plant (0.583), number of secondary branches per plant (0.555), flower diameter (0.525) and length of stalk (0.483). The path coefficient analysis revealed that number of secondary branches had highest positive direct effect (0.6602) on flower yield per plant followed by, number of flowers per plant (0.5872), duration of flowering (0.5332), test weight of 50 flowers (0.4722), flower diameter (0.1200) and days to first flower bud initiation (0.0773), whereas, negative direct effect was executed by length of stalk (-0.9452) followed by number of primary branches (-0.3612) and days to 50 per cent flowering (-0.0151). Number of primary branches had positive indirect effect on flower yield per plant through number of secondary branches (0.6535), Number of secondary branches via number of flowers per plant (0.4701), Length of stalk via number of secondary branches (0.6515). Number of primary branches had negative indirect effect on flower yield per plant through length of stalk (-0.9251), Number of secondary branches via length of stalk (-0.9015), Length of stalk via number of primary branches (-0.3535). Hence direct selection for number of secondary branches per plant, number of flowers per plant and duration of flowering is suggested for getting yield improvement.
