Correlation and path analysis studies in chrysanthemum (Dendranthema grandiflora TZVELEV)

Abstract

Correlation and path analysis were carried out in 20 genotypes of chrysanthemum for different yield attributing traits. The results indicated that the primary branches per plant, plant height after full bloom and days to flower bud initiation 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 primary branches per plant, plant height after full bloom and days to flower bud initiation had highest direct positive effect on number of flowers per plant. At phenotypic level primary branches per plant, plant height after full bloom and days to flower bud initiation showed highest direct positive effect on number of flowers per plant. Highest direct negative effect was observed via days to flowering and flowering duration at phenotypic level whereas at genotypic level it was observed via days to flowering followed by plant height at flower bud initiation stage. Hence direct selection for number of primary branches per plant, plant height after full bloom and days to flower bud initiation is suggested for getting yield improvement.
