Abstract
This study was carried out at El-Mattana Agricultural Research Station, Luxor Governorate, Egypt(lat 25° 17' N, long 32° 33' and alt 76 m ASL)during 2015/16, 2016/17 and 2017/18 harvesting seasons to study the productivity, quality, growth characters and natural infection with several diseases. Ten promising sugarcane genotypes (Saccharum spp.) constituted the studied material and check genotype (commercial genotype), namely GT 54-9 were used as control. Sugarcane genotypes were planted in a randomized complete block design with three replicates. The results of this investigation could be summarized as follow: GT 54-9 had the highest stalk length, stalk weight, sucrose%, purity% and all tested productivity characters. The highest infection with pokkah boeng, smut and mosaic diseases were observed to such genotype while, this genotype uninfected by streak disease. G 84-47 owned the highest brix%, sucrose% and cane yield and had lowest DS% for pokkah boeng disease and didn’t infect by smut and two tested virus diseases. However, the highest brix% were recorded to G 2006-6, which gained the lowest infection by pokkah boeng and smut, the highest infected by streak disease and uninfected by mosaic disease. The lowest mean values of stalk length, sugar yield and stalk weight were scrutinized to G 2010-26, G2011-74 and G 2011-79, respectively. These genotypes didn’t infect by smut and mosaic diseases. In regard to streak disease, the highest and least infections were recorded to G 2010-26 and G 2011-79, respectively. In addition, the lowest stalk diameter and the highest number of tillers/stool were observed in case of G 2011-13 which had the highest infection by smut and uninfected by the two tested virus diseases. Also, the lowest tested qualitative traits, sugar recovery % and yield were recorded to G2012-50. Also, G 2011-13 and G 2012-50 were the highest infected by smut and uninfected by the two tested virus diseases. G 2010-7 and G 2011-82 showed no distinct behavior for all traits. Both genotypes uninfected by smut and the two tested virus diseases. It could be concluded that, GT 54-9 genotype is suitable for regions which were contaminated only by streak disease for highest stalk weight, cane and sugar yields and G 84-47 for regions which, was contaminated by smut and the two tested virus for its highest cane yield. The traits of other genotypes were differed from season to other and had different responses to tested diseases.
