ABSTRACT
An field experiment was conducted to evaluate correlation coefficients among the quantitative characters with growth and yield characters in turmeric cultivars results reveled that, fresh rhizome yield per hectare had significant and positively correlated with plant height (+0.731**0), number of tillers (+0.726**), number of leaves (+0.325*), petiole length (+0.658**), leaf area index (+0.648**), number of mother rhizome(+0.394**), number of primary fingers(+0.600**), number of secondary fingers(+0.613**), weight of mother rhizome(+0.543**), weight of primary fingers (+0.614**), weight of secondary fingers(+0.684**), length of primary fingers(+0.771**), yield per plant(+0.773**) most susceptible to leaf blotch Cuddapah (25.23%) and higher incidence was recorded in Cuddapah (24.01%) followed by Belgaum Local (23.90%) and Bidar-4 (23.53%) and also lowest incidence of leaf blotch, shoot borer was observed in Salem, Rajapuri, Prathibha and CLT-325 were found to be superior in terms of growth, yield and quality parameters.
Key words: Correlation, Yield, Growth, Cultivars.
