Correlation and path analysis were carried out in 24 genotypes of chrysanthemum for different yield attributing traits. The results indicated that the primary branches per plant, plant spread and flowering duration showed positive significant correlation with number of flowers per plant at both genotypic and phenotypic level. The path coefficient analysis at genotypic level revealed that day to flowering, number of primary branches per plant and plant spread had highest direct positive effect on number of flowers per plant. At phenotypic level flowering duration, number of primary branches per plant and plant spread showed highest direct positive effect on number of flowers per plant. Highest direct negative effect was observed via plant height after full bloom on number of flowers per plant at phenotypic level whereas at genotypic level it was observed via days to flower bud initiation followed by plant height at flower bud initiation stage. Hence direct selection for number of primary branches per plant, plant spread and flowering duration is suggested for getting yield improvement.
