Genetic variability, correlation studies and path analysis in sugarcane early clones

Abstract

An experiment was conducted at CCS Haryana Agricultural University, Regional Research Station, Kaul, Kaithal during February 2022- March 2023 using a set of twelve early sugarcane clones along with three checks to explore variation and the association among them. The analysis of variance revealed significant differences among the genotypes for all the characters under study indicating the existence of genetic variability. Phenotypic coefficient of variation (PCV) was found higher than genotypic coefficient of variation (GCV) for all the traits. Results showed that cane yield exhibited highly significant positive correlation with CCS yield, number of millable canes, stalk length, stalk diameter, single cane weight and germination% at both genotypic and phenotypic levels. Path analysis revealed that single cane weight exerted maximum positive direct effect on cane yield. Overall the data generated from this particular trial gives an estimation and prediction of cane yield and provides reliable guidance for selecting the best clones for planting in future years.
