Abstract

Correlation and path coefficient analysis was undertaken among agronomic and economic characters of importance in sugarcane (Saccharum spp.). Fourteen promising sugarcane genotypes (G99-103, G2003-44, G2003-47, G2003-49, G2004-27, G2010-8, G2007-61, G2010-7 G2010-26, G201182, G2011-84, G2014-233 and G84-47) in addition to the commercial cultivar GT 54-9 were evaluated in a replicated field experiment at Giza Research Station (Giza Governorate) in 2017/2018 and 2018/2019 seasons for six morphological characters. Analysis of variance revealed significant differences among genotypes for all the characters studied. Cane yield showed positive and highly significant correlation with single cane weight, stalk length and millable cane number. There was an also positive and significant correlation of cane diameter and number of internodes with cane yield. Length of internode had positive but insignificant correlation with cane yield. Single cane weight had the highest positive direct effect on cane yield followed by millable cane number. Stalk diameter and stalk length were positively and significantly correlated with cane yield, which was due to the indirect effect of single cane weight. Results indicate that the genotypes should be selected on the basis of single cane weight and millable cane number for getting higher sugarcane yield.
