Abstract:

Eight new sugarcane genotypes with two standard check varieties were tested in randomized complete block design (RCBD) with three replications for three cropping season at Finchaa and Metehara Sugar Estate of Ethiopia. The combined analysis of variance revealed that, variance due to location was higher than the other effects based on the relative contribution of sum of squares which is suggesting the existence of differences among the two locations and selection practices without considering location discourages breeding options. Although the difference is very small, the estimates of phenotypic coefficient of variation were higher than the genotypic coefficient of variation for all traits indicating variation is not only due to genotypic but also due to environmental influences. The number of millable cane, number of tillers, cane yield, weight of single stalk and estimated sugar yield were revealed the highest genotypic and phenotypic coefficient of variation.
