Genetic Variability, Heritability And Genetic Advance In Sugarcane

Twenty genotypes were evaluated in a replicated trial to estimate phenotypic and genotypic coefficients of variation, heritability and genetic advance for ten traits in sugarcane (Saccharum officinarum L.). Analysis of variance revealed highly significant differences between genotypes for all the traits studied. High GCV and PCV were recorded for all the traits however the sugar yield recorded highest GCV and PCV followed by cane weight. High heritability estimates and maximum genetic gain as per cent of mean was observed for all traits. This indicates that a scope to improve cane yield by adopting suitable breeding procedures.
