| Abstract | ||||
| A field experiment was conducted during 2008-2012 in Shandweel Research Station, Sohag Governorate (latitude of 26°.55 N & longitude of 31°.7 E) to study the ratooning ability of five promising sugarcane varieties, viz. G.84-47, G.2003-47, G.2003-49, G.98-28, G.99-160 compared to the commercial G.T.54-9 variety. The tested varieties were arranged in a randomized complete block design in three replications. The evaluated genotypes were assessed for their regeneration capacity based on number of stalks/m2, stalk diameter, sucrose, cane and sugar yields up to 2nd ratoon. The tested genotypes significantly differed in sucrose content, cane and sugar yields. Among the studied genotypes, G.2003-47, consistently maintained the highest cane yield/fed, while the commercial variety produced the highest sugar yield as compared to the other genotypes up to the 2nd ratoon crop. It was found that G.2003-47 genotypes possesses better multiratooning ability with high cane and sugar yields and could be exploited successfully beside the commercial variety G.T.54-9. | ||||
