Character association of different turmeric genotypes in Terai region of West Bengal
S Man, S Chakraborty, A Sarkar, A Kundu and MK Debnath
An investigation was carried out in the university farm land of 22 genotypes for two years 2018-19 and 2019-20 and character association was done of 10 DUS characters where genetic parameters like co-efficient of variation, genotypic variance, phenotypic variance, GCV, PCV, heritability and genetic advance the results were evaluated for finding out the influence of additive genes or non additive genes of all characters in the next generation. Path analysis of the characters was also done for 2018-19 and 2019-20 to find out the direct and indirect effects of all the characters among themselves on dependant character yield. Plant height was found as a heritable genetic character (which has moderate heritability) and moderately high GA indicates as it is strongly influenced by additive genes for expression for crop improvement programme in the next generation. Single Rhizome wt although does not have high heritability, but the influence of additive genes is found in the two generations. From the results of path analysis plant height character was found to have strong direct significant positive effect on dependant character yield and number of primary rhizome had direct significant negative effect on projected yield. Selection of character (Plant Height, Plot yield) is found on the basis of genotypic coefficient of variation, phenotypic coefficient of variation, genetic advance by which crop improvement programme can be set up for future generations where action of additive genes will determine the expression of genetic characters in each genotype.
