| Abstract | ||
| 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 out yield from program of Egyptian breeding sugarcane and the commercial cultivar (GT.54-9) were evaluated, clustered and determined the association among their important traits in this study. The experiments were carried out at El-Mataana locations Agriculture Research Center Station, Luxor Governorate (Latitude 25°41′N, Longitude 32°39′E), sugarcane seed sets was planted as spring in two seasons from 2018 to 2020 as plant cane crop. The experiments were led out in a CRD. It could be concluded from the collected results that, G.99-103 genotype was surpassed all sugarcane genotypes in millable cane yield and also obtained tallest stalks and largest stalk circumference as well as heaviest weight stalk. Meanwhile, G.2003-47 genotype was surpassed in total solids %, brix and sucrose%. While, both genotypes had highest values with insignificant difference between them in juice, sugar and their bagasse yield and also purity%, sugar recovery% and total phenolic content in juice. Positive correlation was found between stalk weight with brix, sucrose, cane yield and juice yield, as same 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 low yield mean, was had two genotypes G.95-19 and G.98-28. Cluster II moderate yield mean, enclosed of five genotypes G.84-47, G.2003-47, G.2003-49, G.2004-27 and cultivated variety GT.54-9. The last cluster III high yield, only one genotype was G.99-103. | ||
