| Abstract | ||||
| Six new Egyptian sugar cane varieties and the main commercial one GT 54/9 were planted at El-Mattana Research Station Quena gov-ernorate during 1993, 94 and 95 as plant cane, first and second ratoon crops, respectively, to evaluate technological characters and susceptibility to borer infestation. Analysis of variance for each year and combine analysis over years revealed: 1-Wide variation in brix, sucrose % juice (Pol%), sugar% cane (Richese), sugar extraction% (Rendment), glucose ratio and purity were obsreved among varieties within and over seasons. 2-For most traits the promising varieties were better or at feast equal to the commercial variety. 3-The new varieties were significantly higher in Kg sugar per ton cane (S/TC). Varieties could be arranged in descending order as follows: G 84/47, 84/68, 85/285, 85/166, 85/37 and GT 54/9. 4-Susceptibility to borer infestation (Chile:, agamemnon) was fess in plant cane than the 1st ratoon crop (mean bored joints 5.80% and 10.76% for plant cane and 1st ratoon, respectively). 5-All varieties including the commercial one suffered less than 10% bored joints in•the plant cane and 1st ratoon except G 84/68, 85/ 231 and 85/258 in the 1st ratoon which recorded 10.68%, 15.38% and 17.22% bored joints, respectively. | ||||
