Results of the Fifth Round National Regional Trial for Sugarcane New Varieties in Zhanjiang Region

Results from the trials on two crops of plant cane and one crop of ratoon cane during 2005 and 2006 showed that both cane and sugar yields of YT94-128 was significantly higher than those of ROC10(CK1) and ROC16(CK2), ranking first among the fourteen varieties tested. It performed strong ratooning ability with good agronomic characteristics. Mex105, FN98-1103, CP8 and MT96-1409 were obviously higher in sugar yield than the two checks, but not in cane yield; the ratooning ability of Mex105, CP8 and MT96-1409 was good, but FN98- 1103 poor, all of them presented good agronomic characteristics. GT94-116 and Q170 produced higher cane yield than the two checks, but only given even sugar yield when compared with the checks. YZ99-596 was between the 2 check varieties in both cane and sugar yields. The other tested varieties were poorer than the two checks in yield, sucrose content, ratooning ability, etc.
