Abstract

Genotypic and phenotypic variances, along with their coefficients of variance, heritability and genetic advance were analyzed for nine quantitative traits in 14 sugarcane cultivars (Saccharum officinarum L.). The highest genotypic coefficient of variance and phenotypic coefficient of variance were noted in cane yield (t/ha), commercial cane sugar (CCS) (t/ha), single cane weight (kg), tillering at 120 days and the number of millable canes at harvest. Most of the traits exhibited significant genetic advance except for cane diameter (cm), single cane weight (kg), sucrose and CCS percentage. This indicates potential for improvement in sugar yield through selection, particularly for traits with high variance and genetic advance.
