Genetic variability and heritability studies for cured leaf yield and physiological characters in flue cured Virginia tobacco


Author(s): Netravati and Mohan Kumar HD

Abstract: The present study was undertaken to study the genetic variability and heritability for physiological traits and cured leaf yield, Two F2 populations of FCV tobacco were evaluated for physiological traits and cured leaf yield during Kharif 2016 in RCBD design with three replications. The obtained results indicated that the phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the characters in both the crosses. However, the differences between them were also narrow indicating the lesser role of environment. high heritability coupled with high genetic advance as per cent mean was observed for the characters cured leaf yield, chlorophyll content, stem girth in F2 population TB-70 x TB-102 and cured leaf yield, chlorophyll content, specific leaf area, internodal length in F2 population of cross TB-100 x TB-102. High heritability combined with high genetic adavance indicates that additive gene action play a major role in governing these traits and these traits can be improved by simple selction.
