Why is it important?
Genotypes significantly differed for all the 6 traits indicating sufficient variability in the experimental material. The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all traits studied, indicating that the apparent variation was not only genetic but also was influenced by the growing environment in the expression of the traits. In general, the quantitative trait was highly influenced by the environment. The GCV values were a bit lower ranging from 2.03% to 26.40% while the PCV values ranged from 3.21% to 53.70%. The traits TSH and Fiber showed high GCV and PCV. In the current study, the heritability ranged from 8.65% to 83.86%, while genetic advance as a percentage of the mean showed a wider gain ranging from 6.50% to 33.85%.
Perspectives
It can be concluded from the results of this study that high heritability coupled with high genetic was observed for the characters TSH (ton sucrose ha-1 or sugarcane yield), followed by Fiber percent, Pol percent (%polarization of sugar solution). This indicated that these characters are governed by additive gene action and selection for these characters will be useful in choice of best genotype.
