Correlation and Path Coefficient Analysis in Gladiolus

Studies were carried out to find out the association between different characters and the direction and magnitude of different characters towards total number of florets per spike in 25 genotypes of gladiolus grown over four planting seasons in Delhi. The pooled data were subjected to correlation and path coefficient analysis. Characters like durability of whole spike, number of florets remaining open at a time, rachis length, plant height and number of cormels per plant showed a significant positive correlation with number of florets per spike. Among the characters studied days to 50 per cent heading recorded maximum positive direct effect towards number of florets per spike while days to first floret showing colour showed maximum indirect positive effect.
