Study of Genetic Variability, Heritability and Genetic Advance for Various Yield and Quality Traits in Sugarcane Genotypes (Saccharum officinarum)

Abstract

Study of mean performance, genotypic coefficient of variation, phenotypic coefficient of variation, heritability in broad sense and genetic advance was done using fourteen sugarcane genotypes. These genotypes were tested in randomised block design with four replications. Genotypes significantly differed for all the 13 traits studied indicating sufficient variability was present in the experimental material and the present variability was found heritable for commercial cane sugar Percent, followed by germination Percent, brix percent, polarity value, sucrose content, number of millable canes and number of tillers. Both GCV and PCV estimates were found to be moderate for Germination Percent and Moderate values of genetic advance as percent mean were observed for germination Percent, commercial cane sugar Percent, commercial cane sugar yield, brix percent, polarity value and sucrose content.
