    Comparision of path coefficient analysis and principal component analysis and principal component analysis in turmeric
    (Department of Statistics, College of Veterinary and Animal Sciences, Mannuthy, 1985) Geetha, U; Prabhakaran, P V
    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

    Genotypic variability correlation and path-coefficient analysis in turmeric
    (Kerala Agricultural University, 1987) Geetha, U; Prabhakaran, P V
    Data on 18 biometric characters of 19 varieties of turmeric gathered from a field trial were analysed and the various genetic parameters estimated. High heritability estimates were manifested by girth of mother rhizome at centre and height of the plant. The expected genetic gain from plant height was also high. The correlation studies revealed that all characters were positively related to yield. Path-coefficient analysis showed height of the plant and length of secondary finger were the major contributors towards the rhizome yield.
