| Seven sugarcane promising genotypes, viz. G.84-47, G.95-19, G.98-28, G.99-103, G.2003-47, G.2003-49, G.2004-27 from program of Egyptian sugarcane breeding and the commercial cultivar (GT.54-9) were evaluated, clustered and measured for the association among their important traits. The experiments were carried out at El-Mataana location Agricultural Research Center Station, Luxor Governorate (Latitude 25°41′N, Longitude 32°39′E). Sugarcane seed sets were planted in the spring of two seasons (2018-2019 and 2019-2020) as plant cane crop. The experiments were led out in a randomized complete blocks design with three replications. The results of the statistical analysis of the collected data recorded that, G.99-103 genotype surpassed all studied sugarcane genotypes in millable cane yield, tallest stalks and the largest stalk circumference as well as heaviest stalk weight. Meanwhile, G.2003-47 genotype also surpassed in the total solids%, brix and sucrose%. While, both genotypes had highest insignificant values in juice yield, sugar yield, their bagasse, purity%, sugar recovery% and total phenolic content in juice. With respect to association among traits, positive correlation was found between stalk weight with brix, sucrose, cane yield and juice yield, as well as, cane yield with stalk number per m2 and between sugar yield/fed with stalk weight, brix and sucrose. The eight studied genotypes clustered to three clusters for yield (millable cane, Juice and sugar yield/fed). Cluster I of low yield mean, that included the two genotypes G.95-19 and G.98-28. Cluster II of moderate yield mean, included the five genotypes G.84-47, G.2003-47, G.2003-49, G.2004-27 and cultivated variety GT.54-9. The last cluster III of high yield contained only one genotype (G.99-103). | ||||
