Correlation coefficient analysis in twenty genotypes of gladiolus (Gladiolus grandiflorus L.) were studied at Department of Horticulture, Naini Agriculture Institute, Shuats, Allahabad during the year 2013-2014 for eighteen quantitative characters. It was observed that there were significant correlations spike yield and its contributing characters at both genotypic and phenotypic levels. Shoots/ plant exhibited a high significant correlation with corms/plant. Among spike parameters days to 50% heading, days to first floret colour showing, days to first floret opening and rachis length were found to be associated at high significance with spike yield. The results of investigation revealed that days to first floret colour showing, days to first floret opening, days to last floret opening, florets/spike, rachis length, plant height, shoot/plant and corms/plant are important spike quality characters. Hence, these characters may be considered as selection indices in gladiolus breeding programme.
