Comparision of path coefficient analysis and principal component analysis and principal component analysis in turmeric

Abstract

The discriminant function technique was adopted for the construction of suitable selection indices for rhizome yield in turmeric, utilising the characters selected through principal component analysis and path coefficient analysis and relative discriminating powers of these two multivariate techniques in identifying the pertinent characters aws also evaluated. Data on 18 biometric characters of 19 varieties of turmeric gathered from a field trial conducted by the Department of Plantation Crops, College of Horticulture, Vellanikkara, Trichur during the year 1977- 1978 were utilised for the study
