Studies on Correlation and Path Analysis in Mutants of Coleus (Coleus forskohlii Briq.) for Yield and forskolin Content in V2M1 Generation

The present investigation was carried out during 2003-2007 involving terminal cuttings of coleus ecotype 'Garmai'. Genotypic correlation coefficient between yield and its components in mutants of coleus was studied, viz., plant height, number of branches plant-1, number of leaves plant-1,...
